Offline: A Logical Drive is in an “offline” state if...

No data can be read from it or written to it.

System commands issued to offline logical drives are returned with an error
status: no operations can be performed on offline logical drives. A logical
drive can be “offline” under one of two situations described below:

• It is configured with a redundant RAID level (1, 3, 5, or 0+1), and two

or more of its SCSI drives are not “online”; or

• It is configured at RAID level 0, JBOD, or in a spanned set, and one or

more of its SCSI drives are not “online.”

Logical Drives

See “System Drives.”

Mirroring

Refers to the 100 percent duplication of data on one disk drive to another
disk drive. Each disk will be the mirror image of the other.

Pack

See “Drive Groups (or Drive Packs).”

Parity

See “Rotated XOR Redundancy.”
