4. Repeat these steps until all of your disk drives are installed.  
Caution  
If you plan to operate your VTrak with fewer than a full load of disk  
drives, install all of the drive carriers into the enclosure, to ensure  
proper airflow for cooling.  
Important  
Be sure each drive is securely fastened to its carrier. Proper  
installation ensures adequate grounding and minimizes vibration.  
Do not install drives with fewer than four screws.  
Note  
Unlike other VTrak models, the M310p and M210p do not support  
Parallel ATA disk drives. There is no PATA-to-SATA adapter  
available for these models.  
Drive Numbering  
Each disk drive in VTrak is identified by a number used for creating and  
managing logical drives. VTrak numbers disk drives from left to right. Numbers  
are stamped above each drive bay for easy indentification.

VTrak Setup with CLI or CLU  
After installation, the next step is to configure VTrak.  
To set date, time and IP addresses, you must use the Command Line Interface  
(CLI) or the Command Line Utility (CLU).  
For disk array creation, you can use the CLI, CLU or WebPAM PROe.  
This Chapter only deals with basic functions needed to setup a new VTrak. For a  
full discussion of VTrak functions, refer to WebPAM PROe on page 37 and the  
CLU on page 119.  
VTrak has a Command Line Interface (CLI) to manage all of its functions,  
including customization. A subset of the CLI is the Command Line Utility (CLU), a  
user-level interface that manages your VTrak via your PC’s terminal emulation  
program, such as Microsoft HyperTerminal.  
1. Change your terminal emulation program to match the following settings:  
•
•
•
•
•
Bits per second: 115200

VTrak M310p, M210p Product Manual  
Create a Disk Array  
Click on the Disk Arrays  
icon. The Array Configuration menu appears. Since  
this VTrak is newly activated, there are no disk arrays or logical drives yet.  
There are three options: Automatic, Express and Advanced. Select one and click  
the Next button. Or select one from the dropdown menu on the Create tab.  
Automatic  
The Disk Array Automatic Creation option enables you to create a new disk array  
following a default set of parameters. One logical drive will be made automatically  
when you create the disk array.  
The number of unconfigured physical drives available will determine the RAID  
level of the disk array and whether a spare drive is created.  
When you choose the Automatic option, the following parameters display:  
26  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Chapter 3: Setup  
•
Disk Arrays – The number of physical drives in the disk array, their ID  
numbers, configurable capacity and the number of logical drives to be  
created  
•
•
Logical Drives – The ID number of the logical drive(s), their RAID level,  
capacity and stripe size  
Spare Drives – The physical drive ID number of the dedicated hot spare  
assigned to this disk array  
If you accept these parameters, click the Submit button. The new disk array  
appears in the Disk Array List on the Information tab.  
If you do NOT accept these parameters, use the Express (below) or Advanced  
(page 29) option to create your disk array.  
Express  
The Disk Array Express Creation option enables you to choose the parameters  
for a new disk array by specifying the characteristics you want. With this method,  
you can create multiple logical drives at the same time you create your disk array.  
However, all of the logical drives will be the same size and RAID level.  
If you prefer to specify the parameters directly, use the Advanced option to create  
your disk array.  
If you are uncertain about choosing parameters for your disk array, use the  
Automatic option.

When you first power-up the VTrak, it beeps twice to show normal operation.  
The audible alarm sounds at other times to inform you that the VTrak needs  
attention. But the alarm does not specify the condition. When the alarm sounds:  
•
Check the front and back of VTrak for red or amber LEDs, as described  
above.  
•
•
•
If email notification is enabled, check for new messages.  
Check the different functions in the CLU for component problems.  
Check the event log (see page 154).  
When a continuous tone sounds, there are multiple alarm patterns sounding at  
the same time.

Introduction to RAID  
RAID (Redundant Array of Independent Disks) allows multiple hard drives to be  
combined together in a disk array. Then all or a portion of the disk array is formed  
into a logical drive. The operating system sees the logical drive as a single  
storage device, and treats it as such. The RAID software and/or controller handle  
all of the individual drives on its own. The benefits of a RAID can include:  
•
•
Higher data transfer rates for increased server performance  
Increased overall storage capacity for a single drive designation (such as, C,  
D, E, etc.)  
•
Data redundancy/fault tolerance for ensuring continuous system operation in  
the event of a hard drive failure  
Different types of disk arrays use different organizational models and have  
varying benefits. Also see Choosing RAID Level on page 188. The following  
outline breaks down the properties for each type of RAID disk array:

VTrak M310p, M210p Product Manual  
RAID 0 – Stripe  
When a disk array is striped, the read and write blocks of data are interleaved  
between the sectors of multiple drives. Performance is increased, since the  
workload is balanced between drives or “members” that form the disk array.  
Identical disk drives are recommended for performance as well as data storage  
efficiency. The disk array’s data capacity is equal to the number of disk drive  
members multiplied by the smallest drive's capacity.  
Data  
Stripe  
Disk Drives  
Figure 1. RAID 0 Striping interleaves data across multiple drives  
For example, one 100GB and three 120GB drives will form a 400GB (4 x 100GB)  
disk array instead of 460 GB.  
RAID 0 arrays require one or more physical drives.  
Recommended applications: Image Editing, Pre-Press Applications, other  
applications requiring high bandwidth.

Chapter 7: Technology Background  
RAID 1 – Mirror  
When a disk array is mirrored, identical data is written to a pair of drives, while  
reads are performed in parallel. The reads are performed using elevator seek  
and load balancing techniques where the workload is distributed in the most  
efficient manner. Whichever drive is not busy and is positioned closer to the data  
will be accessed first. With RAID 1, if one drive fails or has errors, the other  
mirrored drive continues to function. This is called Fault Tolerance. Moreover, if a  
spare drive is present, the spare drive will be used as the replacement drive and  
data will begin to be mirrored to it from the remaining good drive.  
Data Mirror  
Disk Drives  
Figure 2. RAID 1 Mirrors identical data to two drives  
Due to the data redundancy of mirroring, the drive capacity of the disk array is  
only the size of the smallest drive. For example, two 100GB drives which have a  
combined capacity of 200GB instead would have 100GB of usable storage when  
set up in a mirrored disk array. Similar to RAID 0 striping, if drives of different  
capacities are used, there will also be unused capacity on the larger drive.  
RAID 1 arrays use two physical drives. You can create multiple RAID 1 disk  
arrays on the same Promise product.  
Recommended applications: Accounting, Payroll, Financial, other applications  
requiring very high availability.

VTrak M310p, M210p Product Manual  
RAID 1E – Enhanced Mirror  
RAID 1E offers the security of mirrored data provided by RAID 1 plus the added  
capacity of more than two disk drives. It also offers overall increased read/write  
performance plus the flexibility of using an odd number of disk drives. With RAID  
1E, each data stripe is mirrored onto two disk drives. If one drive fails or has  
errors, the other drives continue to function, providing fault tolerance.  
Enhanced Data Mirrors  
Disk Drives  
The advantage of RAID 1E is the ability to use an odd number of disk drives,  
unlike RAID 1 and RAID 10. You can also create a RAID 1E Logical Drive with an  
even number of disk drives. However, if you have an even number of disks, you  
will obtain greater security with comparable performance using RAID 10.  
RAID 1E arrays consist of three or more physical drives. You can create an array  
with just two physical drives and specify RAID 1E. But the resulting array will  
actually be a RAID 1.  
Recommended applications: Imaging Applications, Database Servers, General  
Fileservers.

RAID 5 – Block and Parity Stripe  
RAID 5 organizes block data and parity data across the physical drives.  
Generally, RAID Level 5 tends to exhibit lower random write performance due to  
the heavy workload of parity recalculation for each I/O. RAID 5 is generally  
considered to be the most versatile RAID level  
Distributed Parity  
Data  
Blocks  
Disk Drives  
Figure 3. RAID 5 Stripes all drives with data and parity information  
The capacity of a RAID 5 disk array is the smallest drive size multiplied by the  
number of drives less one. Hence, a RAID 5 disk array with (4) 100 GB hard  
drives will have a capacity of 300GB. A disk array with (8) 120GB hard drives and  
(1) 100GB hard drive will have a capacity of 800GB.  
RAID 5 arrays consist of three or more physical drives.  
Recommended applications: File and Application Servers; WWW, E-mail, News  
servers, Intranet Servers

RAID 6 – Block and Double Parity Stripe  
RAID level 6 stores dual parity data is rotated across the physical drives along  
with the block data. A RAID 6 disk logical drive can continue to accept I/O  
requests when any two physical drives fail.  
Double Distributed (P and Q) Parity  
Data  
Blocks  
physical drives  
The total capacity of a RAID 6 disk logical drive is the smallest physical drive  
times the number of physical drives, minus two.  
Hence, a RAID 6 disk logical drive with (7) 100 GB hard drives will have a  
capacity of 500 GB. A disk logical drive with (4) 100 GB hard drives will have a  
capacity of 200GB.  
RAID 6 becomes more capacity efficient in terms of physical drives as the  
number of physical drives increases.  
RAID 6 offers double fault tolerance. Your logical drive remains available when  
up to two physical drives fail.  
RAID 6 is generally considered to be the safest RAID level.  
RAID 6 requires a minimum of four physical drives.

RAID 10 – Mirror + Stripe  
Mirroring/striping combines both of the previous RAID 1 and RAID 0 disk array  
types. RAID 10 is similar though not identical to RAID 0+1. RAID 10 can increase  
performance by reading and writing data in parallel while protecting data with  
duplication. At least four drives are needed for RAID 10 to be installed. With four  
disk drives, the drive pairs are striped together with one pair mirroring the first  
pair. The data capacity is similar to a RAID 1 disk array, with half of the total  
storage capacity used for redundancy. An added plus for using RAID 10 is that, in  
many situations, such a disk array offers double fault tolerance. Double fault  
tolerance may allow your logical drive to continue to operate depending on which  
two disk drives fail.

Disk Drives  
Figure 4. RAID 10 takes a data mirror on one drive pair and stripes it over

RAID 10 arrays require an even number of physical drives and a minimum of

RAID 50 – Striping of Distributed Parity  
RAID 50 combines both RAID 5 and RAID 0 features. Data is striped across  
disks as in RAID 0, and it uses distributed parity as in RAID 5. RAID 50 provides  
data reliability, good overall performance and supports larger volume sizes.

Stripes  
Axle 2  
Disk Drives  
Figure 5. RAID 50 Striping of Distributed Parity disk arrays  
RAID 50 also provides high reliability because data is still available even if  
multiple disk drives fail (one in each axle). The greater the number of axles, the  
greater the number of disk drives that can fail without the RAID 50 array going  
offline.  
RAID 50 arrays consist of six or more physical drives.  
Recommended applications: File and Application Servers, Transaction  
Processing, Office applications with many users accessing small files.  
RAID 50 Axles  
When you create a RAID 50, you must specify the number of axles. An axle  
refers to a single RAID 5 array that is striped with other RAID 5 arrays to make  
RAID 50. An axle can have from three to eight physical drives, depending on the  
number of physical drives in the array.  
The chart below shows RAID 50 arrays with 6 to 15 disk drives, the available  
number of axles, and the resulting distribution of disk drives on each axle. VTrak

Choosing a RAID Level  
There are several issues to consider when choosing the RAID Level for your  
VTrak disk array. The following discussion summarizes some advantages,  
disadvantages, and applications for each choice.  
RAID 0  
Advantages  
Disadvantages  
Implements a striped disk array, the  
data is broken down into blocks and  
each block is written to a separate disk  
drive  
Not a true RAID because it is not fault-  
tolerant  
The failure of just one drive will result in  
all data in an disk array being lost  
I/O performance is greatly improved by  
spreading the I/O load across many  
channels and drives  
Should not be used in mission critical  
environments  
No parity calculation overhead is  
involved  
Recommended Applications for RAID 0:  
•
•
•
Image Editing  
Pre-Press Applications  
Any application requiring high bandwidth  
RAID 1  
Advantages  
Disadvantages  
Simplest RAID storage subsystem  
design  
Very high disk overhead - uses only  
50% of total capacity  
Can increase read performance by  
processing data requests in parallel  
since the same data resides on two  
different drives  
Recommended Applications for RAID 1:

Chapter 7: Technology Background  
Stripe Size  
Stripe Size, also called “Stripe Block Size”, refers to the size of the data blocks  
written to, and read from, the physical drives. Stripe Size is specified when you  
create a disk array. In order to change the Stripe Size of an existing disk array,  
you must delete the disk array and create a new one. You can select Stripe Size  
directly when you use the Advanced function to create a disk array. If you use the  
Express function to create a disk array, WebPAM PRO selects the Stripe Size  
when you choose an Application Type.  
The available Stripe Sizes are 8, 16, 32, 64, 128, 256, 512 KB, and 1 MB. 64 KB  
is the default. There are two issues to consider when selecting the Stripe Size.  
First, you should choose a Stripe Size equal to, or smaller than, the smallest  
cache buffer found on any physical drive in the disk array. Selecting a larger  
value slows read/write performance because physical drives with smaller cache  
buffers need more time for multiple accesses to fill their buffers.  
Second, if your data retrieval consists of fixed data blocks, such as with some  
database or video applications, then you should choose that size as your Stripe  
Size.  
If you do not know the cache buffer or fixed data block sizes, Promise suggests  
you select 64 KB as your Stripe Size. Generally speaking, email, POS, and  
webservers prefer smaller stripe sizes. Video and database applications prefer  
larger stripe sizes.  
Sector Size  
A sector is the smallest addressable area on a physical disk drive. Sector Size  
refers to the size of sector measured by the number of bytes of data it can hold.  
The most common sector size is 512 bytes (512 B). Depending on its capacity,  
there can be up to 4,000,000,000 sectors on a single disk drive. The number of  
sectors is limited by the addressing method of the computer's operating system.  
Sector size is important for two reasons. First, data is written to a disk drive in  
units called blocks. If a data block is smaller than the disk drive's sector size, part  
of the storage space in the sector goes unused. This is why a smaller sector size  
results in a more efficient use of a disk drive’s capacity.  
Second, while a logical drive can be expanded by adding more physical disk  
drives, the number of addresses cannot be increased above 4,000,000,000, as  
noted above. For example, your logical drive has 512 byte sectors, multiplied by  
4 billion addresses. The result is 2,048,000,000,000 bytes or 2 terabytes (TB) of  
data storage capacity. If you simply add more disk drives, your operating system  
will not recognize the additional capacity and you will not be able to use it.  
191

VTrak M310p, M210p Product Manual  
To make use of logical drives greater than 2TB in size, a larger sector size is  
required. The table below correlates sector size with logical drive capacity.  
Logical Drive Size  
8 to 16 TB  
4 to 8 TB  
Sector Size  
4096 bytes (4 KB)  
2048 bytes (2 KB)  
1024 bytes (1 KB)  
512 bytes (512 B)  
2 to 4 TB  
0 to 2 TB  
When you create a Disk Array using the Express or Advanced methods, and  
when you create a Logical Drive, you can specify sector size of 512 B; 1, 2, or  
4 KB. 512 B is the default.  
In most cases, you should select the smallest sector size that will allow full use of  
the physical disk drives in your disk array.  
Because logical drives can be expanded, you may encounter a situation where  
the usable capacity of your expanded logical drive is reduced by the addressing  
issue described above. There are two alternatives:  
•
•
Limit your logical drive expansion to within the limits described in the chart.  
Back up your data, then delete your existing logical drive and create a new  
one with a larger sector size.  
Cache Policy  
As it is used with VTrak, the term cache refers to any of several kinds of high-  
speed, volatile memory that hold data moving from your computer to the physical  
drives or vice-versa. Cache is important because it can read and write data much  
faster than a physical drive. There are read caches, which hold data as it is read  
from a physical drive; and write caches, which hold data as it is written to a  
physical drive.  
In order to tune the cache for best performance in different applications, user-  
adjustable settings are provided. Cache settings are made in conjunction with  
logical drives:  
•
•
When you create a logical drive. See “Create a Logical Drive” on page 98  
On an existing logical drive. See “Logical Drive Settings” on page 107  
Read Cache Policy  
•
Read Cache – The read cache is enabled.  
192  
Download from Www.Somanuals.com. All Manuals Search And Download.  
         
Chapter 7: Technology Background  
•
•
Read Ahead – The read cache and the read-ahead feature are enabled.  
Read-ahead anticipates the next read and performs it before the request is  
made. Can increase read performance.  
No Cache – The read cache is disabled.  
Write Cache Policy  
•
Write Back – Data is written first to the cache, then to the physical drive.  
Better performance. VTrak has a cache backup battery to protect data in the  
cache from a sudden power failure.  
•
Write Thru – Also “Write Through”. Data is written to the cache and the  
physical drive at the same time. Safer.  
Cache Line Size  
The cache line size refers to the size of data the controller handles internally  
during a data input/output (I/O) operation.  
•
8KB – Increases the number of I/O operations. Use this setting if your I/O  
operations are low-bandwidth (512B to 8KB).  
•
64KB – Decreases the number of I/O operations. Use this setting if your I/O  
operations are high-bandwidth (64KB to 1MB).  
If your I/O operations vary or they fall into the mid-bandwidth range (8KB to  
64KB), use either setting.  
Capacity Coercion  
This feature is designed for fault-tolerant logical drives (RAID 1, 1E, 5, 10, and  
50). It is generally recommended to use physical drives of the same size in your  
disk arrays. When this is not possible, physical drives of different sizes will work  
but the system must adjust for the size differences by reducing or coercing the  
capacity of the larger drives to match the smaller ones. With VTrak, you can  
choose to enable Capacity Coercion and any one of four methods.  
Enable Capacity Coercion and select the Method in the Controller Settings menu.  
The choices are:  
•
•
•
•
GB Truncate – (Default) Reduces the useful capacity to the nearest  
1,000,000,000 byte boundary.  
10GB Truncate – Reduces the useful capacity to the nearest  
10,000,000,000 byte boundary.  
Group Rounding – Uses an algorithm to determine how much to truncate.  
Results in the maximum amount of usable drive capacity.  
Table Rounding – Applies a predefined table to determine how much to  
truncate.

VTrak M310p, M210p Product Manual  
Capacity Coercion also affects a replacement drive used in a disk array.  
Normally, when an physical drive fails, the replacement drive must be the same  
capacity or larger. However, the Capacity Coercion feature permits the  
installation of a replacement drive that is slightly smaller (within 1 gigabyte) than  
the remaining working drive. For example, the remaining working drives can be  
80.5GB and the replacement drive can be 80.3, since all are rounded down to  
80GB. This permits the smaller drive to be used.  
Without Capacity Coercion, the controller will not permit the use of a replacement  
physical drive that is slightly smaller than the remaining working drive(s).  
Initialization  
Initialization is done to logical drives after they are created from a disk array.  
Initialization sets all data bits in the logical drive to zero. The action is useful  
because there may be residual data on the logical drives left behind from earlier  
configurations. For this reason, Initialization is recommended for all new logical  
drives. See “Logical Drive Initialization” on page 108.  
Caution  
When you initialize a logical drive, all the data on the logical drive  
will be lost. Backup any important data before you initialize a  
logical drive.  
Hot Spare Drive(s)  
A hot spare is a disk drive that is connected to the disk array system but is not  
assigned as a member of the disk array. In the event of the failure of a drive  
within a functioning fault tolerant disk array, the hot spare is activated as a  
member of the disk array to replace a drive that has failed.  
VTrak will replace a failing disk drive in a disk array with an unassigned drive, if  
one is available. The unassigned drive is not part of any disk array. Such a drive  
is called a hot spare drive. There are two types:  
•
•
Global – An unassigned disk drive available to any disk array on the VTrak.  
Dedicated – An unassigned disk drive that can only be used by a specified  
disk array.  
The hot spare policy function lets you select whether a disk array will access any  
unassigned disk drive or a designated drive in the event of disk drive failure. See  
“Spare Drive” on page 114 (WebPAM PROe) or “Spare Drive Management” on  
page 155 (CLU) for information on how to make this setting.  
194

Chapter 7: Technology Background  
The spare drive effectively takes the place of the failed drive and the RAID  
system immediately begins to rebuild data onto the drive. When the rebuild is  
complete, the disk array is returned to fault tolerant status.  
VTrak includes a function that enables you to return a hot spare drive from a disk  
array back to spare status. When you create the hot spare drive, check the  
Revertible box to enable this feature. See “Transition” on page 200.  
See also “Critical & Offline Disk Arrays” on page 228.  
Partition and Format the Logical Drive  
Like any other type of fixed disk media in your system, a RAID logical drive must  
also be partitioned and formatted before use. Use the same method of  
partitioning and formatting on an logical drive as you would any other fixed disk.  
Depending on the operating system you use, there may or may not be various  
capacity limitations applicable for the different types of partitions.  
RAID Level Migration  
To migrate a disk array is to do one or both:  
•
•
Change its RAID level  
Increase the number of disk drives (sometimes called Expansion)  
Migration takes place on an existing Functional disk array without disturbing the  
existing data. While the disk array is migrating, you can access the data as  
before. When migration is complete, your disk array will have a different RAID  
level and/or a larger capacity.  
Different types of disk arrays use different organizational models and have  
varying benefits. The following outline breaks down the properties for each type  
of RAID supported by Promise products.

Important  
•
•
The Target disk array may require more disk drives than the  
Source disk array  
If the Target disk array requires an EVEN number of disk  
drives but the Source disk array has an ODD number, ADD a  
disk drive as part of the migration process  
•
•
•
You cannot reduce the number of disk drives in your disk  
array, even if the Target disk array requires fewer disk drives  
than the Source disk array  
RAID 1 (mirroring) works with two drives only. Only a single-  
drive RAID 0 disk array or a single-drive JBOD can migrate to  
RAID 1. Other RAID Levels use too many drives to migrate  
You cannot migrate a disk array when it is Critical or  
performing activities such as Synchronizing, Rebuilding, and  
PDM  
Ranges of Disk Array Expansion  
There are limitations to how large you can expand a disk array, depending on the  
size of your current disk array.  
The current SCSI HBA cards and PC Operating Systems support a 10-byte LBA  
format. This means that a disk array can have up to 4 billion address blocks or  
sectors.  
Multiply the number of blocks by the sector size to find the capacity of a disk  
array:  
4,000,000,000 blocks x 512 bytes per sector = 2,048,000,000,000 bytes  
of data for a 2TB drive.  
Note that you cannot change the size of the sectors nor can you increase the  
number of address blocks above 4 billion.  
As a result, there are range limits imposed upon disk array expansion as shown  
in the table above. For example:  
•
•
You can expand a 2.5 TB disk array up to 4 TB  
You can only expand a 1.9 TB disk array up to 2 TB  
See the chart below.

You can direct WebPAM to expand a logical drive beyond the maximum  
expansion size. When the expansion is finished, WebPAM will show the logical  
drive in the desired size. However, your operating system might show the logical  
drive at the maximum expansion size (listed in the table above) and the rest of  
the capacity as unformatted disk space.  
At this point, you can:  
•
•
Format the disk space, which results in a second logical drive  
Create a new logical drive. See below  
Create a New Logical Drive  
To create a new logical drive:  
1. Backup the data from the current logical drive.  
2. Delete the current logical drive.  
See page 100 (WebPAM PROe) or page 147 (CLU).  
3. Create a new logical drive with the desired capacity.  
See page 98 (WebPAM PROe) or page 146 (CLU).  
4. Restore the data to the new logical drive.  
Media Patrol  
Media Patrol is a routine maintenance procedure that checks the magnetic media  
on each disk drive. Media Patrol checks all physical drives assigned to disk  
arrays. Media Patrol does not check unconfigured drives.  
Media Patrol will also check spare drives, if those drives have Media Patrol  
enabled. Media Patrol for spare drives is enabled by default. You can disable it in  
VTrak’s Command Line Interface (CLI).  
Unlike Synchronization and Redundancy Check, Media Patrol is concerned with  
the condition of the media itself, not the data recorded on the media. If Media  
Patrol encounters a critical error, it triggers PDM if PDM is enabled.  
See “Physical Drive Media Patrol” on page 91.

Chapter 7: Technology Background  
Predictive Data Migration (PDM)  
Predictive Data Migration (PDM) is the migration of data from the suspect disk  
drive to a spare disk drive, similar to Rebuilding a Logical Drive. But unlike  
Rebuilding, PDM constantly monitors your disk drives and automatically copies  
your data to a spare disk drive before the disk drive fails and your Logical Drive  
goes Critical.  
After the data is copied from the suspect disk drive, the controller marks it with a  
Stale configuration and a PFA error.  
You can clear the Stale configuration and PFA error and put the disk drive back  
into service. See “Clear Physical Drive Conditions” on page 89 for WebPAM  
PROe or see “Clear Stale and PFA Conditions” on page 139 for the CLU. In most  
cases, however, you will remove the disk drive for repair or replacement.  
PDM Triggers  
The following actions trigger PDM:  
•
•
•
A disk drive with unhealthy status (see below)  
Media Patrol finds a disk critical error*  
You initiate PDM manually  
*PDM also counts the number of media errors reported by Media Patrol.  
A disk drive becomes unhealthy when:  
•
•
A SMART error is reported  
The bad sector remapping table fills to the specified level  
Because data would be lost if written to a bad sector, when a bad sector is  
detected, the disk drive creates a map around it. These maps are saved in the  
bad sector remapping table, which has a capacity of 512 reassigned blocks and  
1024 error blocks.  
When the table fills to a specified percentage of its capacity, PDM triggers a  
migration of data from the suspect drive (the disk drive with the bad sectors) to a  
spare disk drive.  
During data migration, you will have access to the Logical Drive but it will respond  
more slowly to read/write tasks because of the additional operation. The time  
required for data migration depends on the size of the disk drive.

VTrak M310p, M210p Product Manual  
Transition  
The Transition feature enables you to specify “permanent” spare drives for your  
VTrak subsystem. Transition is the process of replacing a revertible spare drive  
that is currently part of a disk array with an unconfigured physical drive or a non-  
revertible spare. The revertible spare drive returns to its original status.  
Transition happens automatically when the following sequence of events takes  
place:  
•
You create a revertible spare drive.  
See page 113 (WebPAM PROe) or page 155 (CLU).  
•
•
•
•
•
A physical drive assigned to your disk array fails and the array goes critical  
or degraded.  
VTrak automatically rebuilds your array to the revertible spare drive and the  
array becomes functional again.  
You replace the failed physical drive with a new physical drive of equal or  
greater capacity.  
VTrak automatically transitions (moves) the data from the revertible spare to  
the new physical drive.  
The new physical drive becomes part of the array and the revertible spare  
drive returns to its original spare status.  
Transition happens manually when you specify a different unconfigured physical  
drive to transition (move) the data from the revertible spare drive.  
See the example below.  
Example  
Following is an example to explain the Transition function.

Chapter 7: Technology Background  
In the example above, there is a four-drive RAID 5 disk array and a global spare  
drive. Physical drives 1, 2, 3, and 4 belong to the disk array. Physical drive 5  
remains unconfigured. Physical drive 6 is a revertible spare drive.  
If a physical drive fails in a disk array and there is a spare drive of adequate  
capacity available, the controller automatically rebuilds the array using the spare  
drive. In this example, physical drive 3 failed and the array is rebuilt using  
physical drive 6, the revertible spare drive.  
When the rebuild is complete, the spare drive has replaced the failed drive. In this  
example, failed drive 3 was replaced by spare drive 6. The disk array now  
consists of physical drives 1, 2, 4, and 6.  
There is no spare drive at this moment. Even if physical drive 5 is of adequate  
capacity, it has not been designated as a spare, therefore the controller cannot  
use it as a spare.

VTrak M310p, M210p Product Manual  
Automatic Transition  
At this juncture, you would replace the failed drive in slot 3 with a new one of the  
same or greater capacity.  
When the VTrak controller detects the new drive in slot 3, it will:  
•
•
Automatically transition the data on drive 6 to drive 3  
Return drive 6 to spare status  
When the Automatic Transition is finished, physical drives 1, 2, 3, and 4 belong to  
the disk array and physical drive 6 is a revertible spare drive. The original  
configuration is restored.  
Manual Transition  
If you wanted to use the drive in slot 5 as a member of the disk array, rather than  
the drive in slot 3, you would run the Transition function manually. See page 103  
(WebPAM PROe) or page 146 (CLU).  
When the Manual Transition is finished, physical drives 1, 2, 4, and 5 belong to  
the disk array and physical drive 6 is a revertible spare drive.  
At this point, you would replace the drive in slot 3. The new drive in slot 3 will be  
unconfigured until you assign it to a disk array or as a spare.

When you first power-up the VTrak, it beeps twice to show normal operation.  
The audible alarm sounds at other times to inform you that the VTrak needs  
attention. But the alarm does not specify the condition. When the alarm sounds:  
•
Check the front and back of VTrak for red or amber LEDs, as described  
above.  
•
If email notification is enabled, check for new messages.  
•
•
Check for yellow !s red Xs  
in Tree View (see page 210).  
Check the event log. See page 49 (WebPAM PROe) or page 154 (CLU).  
When a continuous tone sounds, there are multiple alarm patterns sounding at  
the same time.

To check a component’s installation, follow the same procedure as replacing the  
component, except that you reinstall the original component rather than a new  
one. In most cases, this action fixes a bad connection and allows VTrak to detect  
the component. If this action does not correct the problem, replace the unit. See  
page 167 for instructions.

If the Controller Status LED is amber, restart the VTrak. See “Restart the

If the Controller Status LED continues to display amber after startup, contact  
Promise Technical Support. See “Contact Technical Support” on page 239.  
The Dirty Cache LED flashes during input/output operation. If the LED shines  
amber and the power is off, there is unsaved data in the cache. Do NOT power  
down the VTrak while this LED is on. See “Unsaved Data in the Controller Cache”  
on page 236 for more information.  
CLU Reports a Problem  
The CLU reports information passively—you must determine which functions to  
check based on the sound of the VTrak’s audible alarm (see page 203) and any  
amber or red LEDs (see page 204).  
In this example, let us check disk array status.  
1. Open the CLU.  
2. Highlight Disk Array Management and press Enter.  
3. Observe the status of your disk arrays.

VTrak M310, M210p Product Manual  
Critical & Offline Disk Arrays  
A fault-tolerant disk array—RAID 1, 1E, 5, 6, 10, and 50—goes critical when a  
disk drive is removed or fails. Due to the fault tolerance of the disk array, the data  
is still available and online. However, once the disk array goes critical, the disk  
array has lost its fault tolerance, and performance may be adversely affected.  
If the fault was caused by a failed drive that was removed, the drive must be  
replaced by another drive, either identical or larger, in order for the RAID system  
to rebuild and restore optimal configuration.  
If your fault-tolerant disk array—RAID 1, 1E, 5, 6, 10, and 50— goes offline,  
contact Promise Technical Support. See “Contact Technical Support” on  
page 239.  
Warning  
Take no further corrective action until you have consulted with  
Promise Technical Support.  
A non-fault tolerant disk array—RAID 0—goes offline when a disk drive is  
removed or fails. Since the disk array is not fault tolerant, the data stored in the  
disk array is no longer accessible.  
If one disk drive fails, all of the data on the disk array is lost. You must replace the  
failed drive. Then, if the disk array had more than one disk drive, delete the disk  
array and re-create it. Restore the data from a backup source.  
When a Disk Drive Fails  
VTrak provides both audible and visual indicators to alert you of a disk drive  
failure. The following will occur when a disk drive fails or goes offline:  
•
•
•
•
The Disk Array LED changes from green to amber. See page 204.  
The Disk Carrier Status LED changes from green to red. See page 205.  
The audible alarm repeatedly sounds two short beeps. See page 203.  
WebPAM PROe reports the condition. See page 210.  
With a Hot Spare Drive  
When a physical drive in a disk array fails and a spare drive of adequate capacity  
is available, the disk array will begin to rebuild automatically using the spare  
drive.  
After the disk array rebuilds itself using the spare drive, you must replace the  
failed drive.

Chapter 8: Troubleshooting  
To set up a spare drive, see “Create Spare Drive” on page 113 (WebPAM PROe)  
or “Create New Spare Drive” on page 155 (CLU).  
Without a Hot Spare Drive  
If there is no hot spare drive of adequate capacity, you must remove the failed  
drive and install an unconfigured replacement drive of the same or greater  
capacity in the same slot as the failed drive. Until you install the replacement  
drive, the logical drive will remain Degraded.  
•
If the Auto Rebuild function is ENABLED, the disk array will begin to rebuild  
automatically as soon as you replace the failed drive.  
•
If the Auto Rebuild function is DISABLED, you must manually rebuild the  
disk array after you replace the failed drive.  
To enable Automatic Rebuild, see page 50 (WebPAM PROe) or page 153 (CLU).  
To set Hot Spare Policy, see page 112 (WebPAM PROe) or page 155 (CLU).  
Important  
If your replacement disk drive was formerly part of a different disk  
array or logical drive, you must clear the configuration data on the  
replacement drive before you use it.  
See “Clear Physical Drive Conditions” on page 89 (WebPAM  
PROe) or “Clear Stale and PFA Conditions” on page 139 (CLU).

VTrak M310, M210p Product Manual  
Overheating  
Overheating is a potentially serious condition because the  
excessively high temperatures can lead to disk drive failure and  
controller malfunction.  
Overheating usually results from:  
•
•
Fan failure  
Poor air circulation around the enclosure  
WebPAM PROe reports failed fans along with elevated  
temperature. On VTrak, there are two kinds of fans:  
•
•
Power supply, 1 fan each, 2 fans total  
Cooling units, 2 fans each  
If a power supply fan fails, you must replace the power supply. If  
a cooling unit fan fails, you can remove the cooling unit and  
replace only the fan itself.  
No tools are required for either procedure. See page 172 for  
instructions on replacing the fans.  
Air circulation around the VTrak enclosure may be a more  
complex problem. Use the thermometer icons to help you locate  
the specific hot spot. Check for these conditions:  
•
•
Accumulated dust or objects blocking the fans  
Less than a minimum of 5 inches (13 cm) space between the  
back of the VTrak and the wall or other object  
•
Ambient temperature above 95°F (35°C) where the VTrak is  
operating  
To cool down a VTrak:  
•
•
Correct any problems identified above  
Power it down and let it sit for an hour or longer

Chapter 8: Troubleshooting  
Power Supplies  
VTraks are equipped with redundant power supplies. The  
advantage of dual power supplies is that, should one fail, the  
other will continue powering the subsystem until the faulty one  
can be replaced. VTrak is capable of operating on a single power  
supply. As a result, if one power supply fails you must watch the  
front panel LEDs or WebPAM PROe in order to become aware of  
the condition.  
The power supplies are hot-swappable, meaning you can leave  
the VTrak running when you replace the bad one. Be careful,  
however, to remove the faulty power supply and not the good  
one, or VTrak will come to an immediate stop and your data will  
be unavailable until the system is powered and booted again.  
As noted above, if a power supply fan fails, you must replace the  
power supply. Without the fan to cool it, the power supply will  
overheat and eventually fail anyway.  
No tools are required for the procedure. See your page 171 for  
instructions on replacing a power supply.  
Battery  
VTrak uses a battery as backup power for the cache. Should a  
power failure occur, the battery enables the cache to hold data up  
to 72 hours. The battery recharges during normal VTrak  
operation.  
In most cases, installing a replacement battery will correct a  
marginal or failed condition. The battery is located on the left  
cooling unit. Remove the cooling unit for access. The battery is  
hot-swappable.  
No tools are required for the procedure. See See page 175 for  
instructions on replacing the battery.

VTrak M310, M210p Product Manual  
Connection Problems  
When you install your Promise product following the instructions in the Quick  
Start Guide and this Product Manual, you should have little trouble getting your  
equipment to work the first time. But connection problems can arise that are not  
the User's or Installer's fault. Every conceivable problem cannot be covered in  
the documentation but some guidelines could be helpful.  
Connection problems cause a majority of failures in almost any electrical system.  
While the installation of the cables and components was correct, they don't  
function properly, or at all, because:  
•
•
•
•
A connector is dirty or corroded  
A connector is loose or damaged  
A cable looks OK outside but has an open circuit inside  
The wrong cable was used  
VTraks ship with a full set of new cables, as required for each specific model. Be  
sure to use these components because: 1.) They are the proper ones for your  
RAID subsystem, 2.) They are in brand-new condition, and 3.) You paid for them  
with the purchase of your VTrak.  
SCSI Connections  
VTrak uses a network connection to pass command and management  
information. Data is transmitted via the SCSI bus. Proper termination and SCSI-3  
compliant cables are required for the system to operate correctly.  
SCSI connections are both physical (outside) and electrical (inside). You can see  
a physical connection, you can clean it or try a different cable on it. Electrical  
connections are made by firmware and software.  
VTrak makes use of SCSI Target IDs (TIDs) and Logical Unit Numbers (LUNs) to  
enable multiple VTrak arrays managed by a single Host PC  
SCSI channels are completely intolerant of TID conflicts. If you have a conflict,  
the devices on your SCSI chain will not work correctly until it is resolved.  
The VTrak RAID subsystem is sensitive to the presence of other devices on the  
SCSI chain. Do not connect other devices to the SCSI chain with a VTrak, except  
for an other VTrak.  
Termination  
VTrak has an internal termination feature but it works only on the “Out” connector.  
Internal termination is set to “Automatic” by default. For termination settings, see  
“SCSI Channel Settings” on page 62 or “Channel Settings” on page 151.

CONSOLE  
Mgmt  
SCSI “Out”  
connector  
SCSI “Out”  
connector  
This means you can, for example, connect your Host PC to one of the VTrak’s  
SCSI “In” ports without the need of an external SCSI terminator. You can also  
connect both SCSI connectors in a “daisy-chain” with other VTraks.  
Be sure to enable termination on the last VTrak in the chain. Promise  
recommends that you attach the SCSI cable to the “In” connector and set the  
internal termination to “On” or “Automatic”.  
Or you can attach the SCSI cable to the “Out” connector and install a physical  
terminator (not supplied) onto the “In” connector.  
Serial Connections  
VTrak uses a serial connection for the command line interface (CLI) and the  
command line utility (CLU). After you set the IP address, you can access the CLI  
and CLU through a network connection, also. Normally, users prefer WebPAM  
PROe because of its graphic user interface. But the CLI and CLU can do the  
same jobs. And they will work when your network connection is down.  
For VTrak, you must use the CLI or CLU to set the Management Port IP address  
in order for WebPAM PROe to connect with it. See “VTrak Setup with CLI or CLU”  
on page 17. This issue is discussed further under Network Connections (below).  
See the “Set Up Serial Cable Connections” on page 14 for more information on  
making the connection.  
The CLI and CLU control and manage but they do not move data. They  
communicates through a null-modem cable, supplied with the VTrak. A straight-  
through serial cable will not work for this purpose. You may choose not use the  
CLI or CLU often and want to disconnect and store the cable. Consider leaving it  
connected, to be sure it will be there when you need it.  
Network Connections  
VTrak has an RJ-45 Management Port connector on the back of its cabinet. This  
is a Gigabit Ethernet connector designed to connect to your network. The VTrak  
becomes a node on your network like any other PC, server or other component  
with an IP address.

address to one that will work with your network. You make the initial IP address

Note that VTrak Management Port can accept IP address assignments from a  
DHCP server. Use VTrak's Command Line Utility (CLU) to enable this feature. If  
you have not activated DHCP support but there is a DHCP server on your  
network, there is a chance that it will inadvertently assign the VTrak’s  
Management Port IP address to another node. You might see a warning to this  
effect on your PC's monitor. If this happens, WebPAM PROe may not be able to  
connect. See your network administrator to work out a suitable arrangement.  
Unsaved Data in the Controller Cache  
An LED (marked with the  
icon) is provided to inform you that there is data in  
the cache that has not been saved to non-volatile memory. Such data is  
sometimes called “dirty,” not to suggest it is corrupted in some way but because it  
has not been saved to a disk drive.

Frequently Asked Questions  
What kind of disk drives can I use with VTrak?  
VTrak supports 1.5 and 3.0 GB/s Serial ATA disk drives.  
Can I take the disk drives from my UltraTrak, put them into the VTrak and  
keep my disk array or logical drive intact?  
Yes. UltraTrak and early VTrak subsystems used a proprietary method of  
disk metadata, stored in the reserve sector of each physical drive. VTrak  
M310p/M210p uses the industry-standard DDF and has a metadata-to-DDF  
conversion feature. To use the conversion feature, you must restart the  
VTrak M310p/M210p after installing disk drives from an older system.  
M310p and M210p do not support Parallel ATA (PATA) disk drives.  
Note that if you move the disk drives from the VTrak M310p/M210p to the  
older subsystems, they will not recognize your disk array or logical drive.  
Can I use my existing SCSI card with VTrak M310p/M210p?  
Yes. However, for best performance results, use an Ultra320 SCSI card.  
How can I tell when the VTrak has fully booted?  
During the VTrak power-up process, the Power, FRU Status, and Logical  
Drive Status LEDs will light up. When the Logical Drive Status LEDs light up,  
the VTrak is fully booted. See pages 37 and 39, or pages 119 and 121.  
Why does VTrak come with a Command Line Utility?  
First, to assign your VTrak an IP address in order for the WebPAM  
management software to connect to it. Second, in the event of a network  
failure, you can still access the VTrak. Third, some users prefer the  
Command Line Utility.

VTrak M310, M210p Product Manual  
My WebPAM connection was working OK. But later on, it timed out. What  
do I do now?  
The network condition can time-out for several reasons. When an open  
connection has no action for a specific amount of time (the Administrator can  
change it), the connection times-out automatically for security reasons.  
When you attempt to use WebPAM, it returns to the login screen. Enter your  
user name and password and click Login, and WebPAM will establish a new  
connection.  
I can access the VTrak over my company’s intranet. But I can’t access it  
from an outside Internet connection. How do I make the Internet connection  
work?  
This condition is not related to VTrak, but is due to your firewall and network  
connection protocol. Contact your MIS Administrator.  
With other Promise VTraks, I used the Server’s IP address in WebPAM to  
connect with the RAID subsystem. Why is this VTrak M310p/M210p  
different?  
VTrak M310p/M210p has the server software embedded. With the M310p/  
M210p, you point your browser directly to the VTrak rather than a server.  
Also, with M310p/M210p you do not have to create a subsystem because  
the subsystem already exists.  
Why can a RAID 1 logical drive on VTrak consist of only two disk drives?  
On VTrak, RAID 1 logical drives work in mirrored physical drive pairs. You  
could create up to six RAID 1 logical drives. Or you can create a single RAID  
10 logical drive with data mirroring and up to 12 physical drives. If you have  
an odd number of drives but still want data mirroring, use RAID 1E.  
See “Install Disk Drives” on page 10 and “Introduction to RAID” on page 179  
for more information on the number of physical drives you can use for each  
RAID level.  
Are logical drives on VTrak limited to 2.199 terabytes?  
No. But verify that your operating system supports logical drives over 2.199  
TB. Also, for the operating system to recognize the full capacity of logical  
drives over 2.199 TB, you must specify a sector size of 1 KB or larger when  
you create the logical drive. See “Sector Size” on page 191 or more  
information.  
I have two UltraTraks and use WebPAM to monitor them. Can I use my  
existing WebPAM setup to monitor the VTraks also?  
No. Use the WebPAM embedded with the VTrak M310p/M210p.

Chapter 9: Support  
How can I be sure everything is working OK on the VTrak?  
Locally: The VTrak enclosure has LEDs on the front to monitor the status of  
power, field replaceable units (FRUs) and logical drives. When these are  
green, VTrak is functioning normally.  
Remotely: Check the Tree Icons in WebPAM. If there are no yellow or red  
warning icons displayed, VTrak is functioning normally.  
What happens if a logical drive goes critical?  
On the front of VTrak, the logical drive LED turns amber and an audible  
alarm sounds. See “Critical & Offline Disk Arrays” on page 228.  
Can VTrak run using just one power supply?  
Yes, it is possible to run VTrak on a single power supply. There are two  
power supplies so that VTrak will continue running if one of the power supply  
fails. But deliberately leaving one power supply off negates this advantage.  
In addition, leaving one power supply off reduces air flow through the VTrak  
enclosure and can contribute to overheating. Always switch on both power  
supplies.
