Glossary
consistency check command
Command that reads all the blocks of a RAID 1 or RAID 5 to
determine if the blocks are consistent. If any inconsistent blocks are
detected, they are fixed.
container
See
array
.
Container
is another term for
array
used in the
Adaptec
SCSI RAID Software Reference Guide
.
D
dead partition
See
failed
.
dedicated hot spare
Component that can take the place of a failed component only on
the fault-tolerant array to which it is explicitly assigned.
degraded
A redundant array in which one or more members have failed such
that data is intact but redundancy has been compromised is in the
degraded state. The array and all data on it is accessible but a
further drive failure would cause the array to fail and result in data
loss.
dirty data
Data that has been written to a
cache
but which has not been
“flushed” out to its final destination.
disk
Physical disk drive. Randomly accessible, re-writable data storage
device. Also called
hard disk
.
disk ID
Unique disk identifier that consists of the channel number, SCSI ID
(target ID), and LUN. For example, (channel:ID:LUN) 1:04:0. See
also
channel
;
LUN
;
SCSI device ID
