Fails to power on.
Power cord not connected properly. Verify that the power cord is properly
connected to the power module.
Power not available at the outlet.
If the DEU is plugged into a three-hole
grounded outlet, verify if power to the
outlet has been interrupted. This can be
accomplished by testing the outlet with a
known working appliance, like a lamp.
Power switch not in the proper
position.
Be sure that the power switch is in the
“ON” position, labeled “I”.
Faulty fuse.
Replace fuse, see Replacing a Fuse

B Glossary
Th e followin g t er m s a r e u sed t h r ou gh ou t t h is m a n u a l
a n d m a y be h elpfu l ba ck gr ou n d in for m a t ion on t h e
t ech n ology.
Asynchronous Operations
Cache Flush
Operations that bear no relationship to each other in time and can
overlap. The concept of asynchronous I/O operations is central to
independent access arrays in throughput-intensive applications.
Refers to an operation where all un-written blocks in a Write-Back
Cache are written to the target disk. This operation is necessary
before powering down the system.
Channel
Refers to one of the SCSI bus connectors on the controllers or
termination interface cards.
Consistency Check
Refers to a process where the integrity of redundant data is verified.
For example, a consistency check of a mirrored drive will make sure
that the data on both drives of the mirrored pair are exactly the same.
For RAID level 3 and 5 redundancy, a consistency check will involve
reading all associated data blocks, computing parity, reading parity,
and verifying that the computed parity matches the read parity.
Disconnect/Reconnect
Disconnect is a function that allows a target SCSI device (typically a
disk drive that received a request to perform a relatively long I/O
operation) to release the SCSI bus so that the controller can send
commands to other devices. When the operation is complete and the
SCSI bus is needed by the disconnected target again, it is
reconnected.
Disk Mirroring
Disk Spanning
Data written to one disk drive is simultaneously written to another disk
drive. If one disk fails, the other disk can be used to run the system
and reconstruct the failed disk.
Several disks appear as one large disk using this technology. This
virtual disk can then store data across disks with ease without the
user being concerned about which disk contains what data. The
subsystem handles this for the user.
Disk Striping
Duplexing
Data is written across disks rather than on the same drive. Segment 1
is written to drive 0, segment 2 is written to drive 1, and so forth until a
segment has been written to the last drive in the chain. The next
logical segment is then written to drive 0, then to drive 1, and so forth
until the write operation is complete.
This refers to the use of two controllers to drive a disk subsystem.
Should one of the controllers fail, the other is still available to provide
disk I/O. In addition, depending how the controller software is written,
both controllers may work together to read and write data
simultaneously to different drives.
Fault-Tolerant
Hot Spare
When something is fault-tolerant it is resistant to failure. A RAID 1
mirrored subsystem, for example, is fault-tolerant because it can still
provide disk I/O if one of the disk drives in a mirrored system fails.
The “Hot Spare” is one of the most important features the controller
provides to achieve automatic, non-stop service with a high degree of

fault tolerance. This rebuild operation will be carried out by the
controller automatically when a SCSI disk drive fails.
Logical Drive
Mapping
A set of contiguous chunks of a physical disk. Logical disks are used
in array implementations as constituents of logical volumes or
partitions. Logical disks are normally transparent to the host
environment, except when the array containing them is being
configured.
The conversion between multiple data addressing schemes,
especially conversions between member disk block addresses of the
virtual disks presented to the operating environment by the array
management software.
Mirroring
Refers to the 100% duplication of data on one disk drive to another
disk drive. Each disk will be the mirror image of the other.
Partition
An array virtual disk made up of logical disks rather than physical
ones. Also called logical volume.
Physical Drive
A physical array (or drive) is a collection of physical disks governed by
the RAID management software. A physical drive appears to the host
computer as one or more logical drives.
RAID
(Redundant Array of Independent Disks) An approach to using
multiple low cost drives as a group to improve performance, yet also
provide a degree of redundancy that makes data loss remote.
RAID 0
Block “striping” is provided, yielding higher performance than is
possible with individual drives. This level does not provide any
redundancy.
RAID 1
RAID 10
RAID 3
RAID 30
RAID 5
Drives are paired and mirrored. All data is 100% duplicated on an
equivalent drive.
RAID 10 is a combination of RAID levels 0 and 1. The data is striped
across disks as in RAID 0. Each disk has a mirror disk, as in RAID 1.
Data is striped across several physical drives. For data redundancy
one drive is encoded with rotated XOR redundancy.
Data striping of two or more RAID 3 arrays. RAID level 30 is a
combination of 0 and 3.
Data is striped across several physical drives. For data redundancy
drives are encoded with rotated XOR redundancy.
RAID 50
RAID level 50 is a combination of RAID level 0 and 5.
RAID Controller
This refers to the controller card that routes data to and/ or from the
CPU. Disk array controllers perform all RAID algorithms onboard the
controller.
Rebuild
The regeneration of all data from a failed disk in a RAID level 1, 3, 5,
or 6 array to a replacement disk. A disk rebuild normally occurs
without interruption of application access to data stored on the array
virtual disk.
Rotated XOR Redundancy
This term (also known as “parity”) refers to a method of providing
complete data redundancy while requiring only a fraction of the
storage capacity for redundancy. In a system configured under RAID

3 and 5, all data and parity blocks are divided between the drives in
such a way that if any single drive is removed (or fails), the data on it
can be reconstructed using the data on the remaining drives. (XOR
refers to the Boolean “Exclusive-OR” operator.)
SAF-TE
Is the acronym for SCSI Accessed Fault-Tolerant Enclosures. It is a
monitoring and communication specification developed by Conner
(nStor) and Intel for sending and receiving server and storage system
status information via the SCSI bus.
Session
Refers to the period of time between any two consecutive system
shutdowns. System shutdown may be either a power off/on, or a
hardware reset.
SCSI Drive
A disk drive equipped with a small computer system interface (SCSI).
Each disk drive will be assigned a SCSI address (or SCSI ID), which
is a number from 0 to 15. The SCSI address uniquely identifies the
drive on the SCSI bus or channel.
Spanning
Disk spanning allows multiple disk drives to function like one big drive.
Spanning overcomes lack of disk space and simplifies storage
management by combining existing resources or adding relatively
inexpensive resources.
Striping
Disk striping writes data across multiple disks rather than on one disk.
disk striping involves partitioning each drive storage space into stripes
that can vary in size from one sector (1 KB) to several megabytes.
Stripe Order
The order in which SCSI Drives appear within a Physical Pack. This
order must be maintained, and is critical to the controller’s ability to
“Rebuild” failed drives.
Stripe Width
Target ID
Refers to the number of kilobytes per stripe block.
A target ID is the SCSI ID of a device attached to the disk array
controller. Each SCSI channel can have up to sixteen SCSI devices
(target ID from 0 to 15) attached to it.
Write-Through Cache
Write-Back Cache
Refers to a cache writing strategy whereby data is written to the SCSI
Drive before a completion status is returned to the host operating
system. This caching strategy is considered more “secure,” since a
power failure will be less likely to cause loss of data. However, a
Write-Through cache results in a slightly lower performance, in most
environments.
Refers to a caching strategy whereby write operations result in a
completion signal being sent to the host operating system as soon as
the cache (not the disk drive) receives the data to be written. The
target SCSI Drive will receive that data at a more appropriate time, in
order to increase controller performance.
