Glossary
check point
A feature that enables you to exit the ACU when an operation is in
progress and be able to continue without interruption. The driver
then resumes the operation from where the BIOS left off and the
BIOS resumes the operation where the driver left off.
chunk
See stripe.
clear
Foreground initialization of a fault-tolerant array. A clear operation
zeros all blocks of the array. The array is not accessible until the
clear task is complete.
concatenation
Joining of physical or logical drives in sequential order.
consistency check command
Command that reads all the blocks of a RAID 1 to determine if the
blocks are consistent. Any inconsistent blocks are fixed.
D
dead partition
See failed.
degraded
A redundant (for example, a RAID 1) array in which one or more
members have failed. The data is intact but redundancy has been
compromised. Any further failure would cause the array to fail and
result in data loss.
disk
Physical disk drive. Randomly accessible, rewritable data storage
device. Also called hard disk.
disk ID
Unique disk identifier that consists of the channel number, SATA
ID. For example, (channel:ID:LUN) 1:04:0. See also channel.
