•
•
Install only the screws supplied with the VTrak.
Install four screws per drive.
Snug each screw. Be careful not to over tighten.
3. Reinstall the drive carrier into the VTrak chassis.
4. Repeat these steps until all of your disk drives are installed.
Cautions
•
•
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.
A VTrak M500f/i/p carrier is shown above. The VTrak
M300f/i/p and M200f/i/p carrier is similar in appearance but
the two carrier designs are NOT interchangeable.
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.

VTrak Setup with CLI or CLU (below)
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
CLU on page 157.
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 settings to match the following:
•
•
•
•
•
Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: none
2. Start your PC’s terminal VT100 or ANSI emulation program.
3. Press Enter once to launch the CLI.
4. At the Login prompt, type administrator, and press Enter.
5. At the Password prompt, type password, and press Enter.
At this point, you are in the CLI. You can continue using the CLI to make
network settings or you can switch to the CLU.

value. Both the sender and peer share a predefined secret. The peer
concatenates the random value, the ID, and the secret and calculates a one-way
hash value. The hash value is sent to the authenticator, which in turn builds that
same string on its side, calculates the sum, and compares the result with the
value received from the peer. If the values match, the peer is authenticated.

Introduction to RAID (below)
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
outline breaks down the properties for each type of RAID disk array:

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.

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.

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

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.

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.

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

VTrak M-Class Product Manual
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 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.
250

Chapter 7: Technology Background
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 135
On an existing logical drive. See “Logical Drive Settings” on page 144
Read Cache Policy
•
Read Cache – The read cache is enabled.
251
Download from Www.Somanuals.com. All Manuals Search And Download.
VTrak M-Class Product Manual
•
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.
252

Chapter 7: Technology Background
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
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
page 202 (CLU) for information on how to make this setting.
253

VTrak M-Class Product Manual
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 258.
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 of the following:
•
•
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.

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 iSCSI, SCSI, and Fibre Channel 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.
Maximum LD

0 to 2 TB
16 TB
8 TB
4 TB
2 TB
4096 bytes
2048 bytes
1024 bytes

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.
256

Chapter 7: Technology Background
2. Delete the current logical drive.
3. Create a new logical drive with the desired capacity.
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.
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
cases, however, you will remove the disk drive for repair or replacement.
PDM Triggers

VTrak M-Class Product Manual
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.
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.
•
•
•
•
•
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.

Chapter 7: Technology Background
Example
Following is an example to explain the Transition function.
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.

VTrak M-Class Product Manual
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.
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 140
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,
do the following:
•
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 269).
When a continuous tone sounds, there are multiple alarm patterns sounding at
the same time.

VTrak M-Class Product Manual
Critical & Offline Disk Arrays
A fault-tolerant disk array—RAID 1, 1E, 5, 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, 10, and 50— goes offline, contact
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 262.
The Disk Carrier Status LED changes from green to red. See page 264.
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
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.
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.

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.
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, do the following:
•
•
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.
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.

VTrak M-Class 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

Chapter 8: Troubleshooting
SCSI “Out”
connectors
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.
iSCSI Connections
A recent variation of the SCSI interface is Internet SCSI (iSCSI), which converts
SCSI commands to TCP/IP commands for communication over a network. VTrak
uses two Gigabit Ethernet network connections to move data under the iSCSI
protocol. The iSCSI ports will accept IP address assignments from a DHCP
server. Also, you can use WebPAM PRO for the initial setup.
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 29. This issue is discussed further under Network Connections
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.
VTrak ships from the factory an IP address of 10.0.0.1. You must change this
address to one that will work with your network. You make the initial IP address
setting using the CLI or CLU. See “VTrak Setup with CLI or CLU” on page 29.

Note that VTrak Management Port can accept IP address assignments from a

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
The VTrak M-Class controller has a 256 MB data memory cache protected by a
battery backup. If there is a power failure while unsaved data is in the cache, the
battery will power the cache and hold the data up to 72 hours.
Dirty Cache LED (Fibre Channel)
Dirty Cache LED (iSCSI)
Dirty Cache LED (SCSI)
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.
If a power failure has occurred and there is unsaved data in the controller’s
cache, the Dirty Cache LED shines amber. During this time, do NOT remove the
cooling unit (M300f/i/p or M200f/i/p) or the cooling unit with the battery
(M500f/i/p). Wait until power service is restored. After the VTrak reboots
completely, the data will be saved automatically and the LED will go dark.
If you have turned off the power manually, turn the power on again and allow the
VTrak to boot itself completely. Then the data will be saved automatically and the
LED will stop flashing.

Frequently Asked Questions (below)
Limited Warranty (page 302)
Returning product for repair (page 303)
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 M-
Class uses the industry-standard DDF and has a metadata-to-DDF
conversion feature. To use the conversion feature, you must restart the
VTrak M-Class after installing disk drives from an older system.
If you plan to move Parallel ATA (PATA) disk drives to VTrak M-Class,
contact your Promise distributor to obtain PATA-to-SATA adapters. You must
install an adapter onto the VTrak’s drive carrier for each PATA disk drive you
want to connect to VTrak’s SATA disk drive interface.
Note that if you move the disk drives from the VTrak M-Class to the older
subsystems, they will not recognize your disk array or logical drive.
Can I use my existing SCSI card with VTrak M-Class?
Yes, if your VTrak is a M500p, M300p or M200p model. However, for best
performance results, use an Ultra320 SCSI card.
How can I tell when the VTrak has fully booted?
When the VTrak is fully booted up, the Power and FRU LEDs will light up
green. If a disk array is present, the Logical Drive LED will light up green
also. The Controller LED blinks five times, once per second; goes dark for
ten seconds; then blinks five times again.
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 M-Class 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 M-Class different?
VTrak M-Class has the server software embedded. With the M-Class, you
point your browser directly to the VTrak rather than a server. Also, with M-
Class 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 seven RAID 1 logical drives. Or you can create a single
RAID 10 logical drive with data mirroring and up to 14 physical drives. If you
have an odd number of drives but still want data mirroring, use RAID 1E.
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
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 M-Class.

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
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.

Disclaimer of other warranties
This warranty covers only parts and labor, and excludes coverage on software
items as expressly set above.
Except as expressly set forth above, Promise DISCLAIMS any warranties,
expressed or implied, by statute or otherwise, regarding the product, including,
without limitation, any warranties for fitness for any purpose, quality,
merchantability, non-infringement, or otherwise. Promise makes no warranty or
representation concerning the suitability of any product for use with any other
item. You assume full responsibility for selecting products and for ensuring that
the products selected are compatible and appropriate for use with other goods
with which they will be used.
Promise DOES NOT WARRANT that any product is free from errors or that it will
interface without problems with your computer system. It is your responsibility to
back up or otherwise save important data before installing any product and
continue to back up your important data regularly.

Chapter 9: Support
No other document, statement or representation may be relied on to vary the
terms of this limited warranty.
Promise’s sole responsibility with respect to any product is to do one of the
following:
a) replace the product with a conforming unit of the same or superior
product;
b) repair the product.
Promise shall not be liable for the cost of procuring substitute goods, services,
lost profits, unrealized savings, equipment damage, costs of recovering,
reprogramming, or reproducing of programs or data stored in or used with the
products, or for any other general, special, consequential, indirect, incidental, or
punitive damages, whether in contract, tort, or otherwise, notwithstanding the
failure of the essential purpose of the foregoing remedy and regardless of
whether Promise has been advised of the possibility of such damages. Promise
is not an insurer. If you desire insurance against such damage, you must obtain
insurance from another party.
Some states do not allow the exclusion or limitation of incidental or consequential
damages for consumer products, so the above limitation may not apply to you.
This warranty gives specific legal rights, and you may also have other rights that
vary from state to state. This limited warranty is governed by the State of
California.
Your Responsibilities
You are responsible for determining whether the product is appropriate for your
use and will interface with your equipment without malfunction or damage. You
are also responsible for backing up your data before installing any product and
for regularly backing up your data after installing the product. Promise is not liable
for any damage to equipment or data loss resulting from the use of any product.
