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. A-4
