The SCSI hard disk subsystem

The following applies if SCSI hard disk drives are operated on a disk array controller:

RAID level 0 and 7

Rebuild is not possible. If a hard disk fails, its data is lost.

RAID level 1 and 5 without standby hard disk

Rebuild on the new disk is carried out automatically when the old disk is swapped.

RAID level 1 and 5 with standby hard disk

A standby hard disk is automatically enabled as a replacement for the defective hard disk and the data of the defective disk is rebuilt on the standby disk.

ÊRead the documentation for the new hard disk drive.
