Glossary-3
Glossary
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
The controller continuously performs a verification on a redundant
array to data integrity. In the case of RAID 1 or 10, consistency
checks assure that the data between like blocks match. In the case
of a RAID 5, consistency checks assure that data in the stripe and
the calculated parity for the stripe match.
container
See
array
.
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.
dirty data
Data that has been written to a
cache
but which has not been
“
flushed
”
out to its final destination.
disk drive
Device for storing non-removable, rewritable media. See also
hard
disk, hard drive
.
disk ID
Unique disk identifier that consists of the channel number, ID, and
LUN (channel:ID:LUN), for example, 1:04:0. See also
channel
.
