System components and expansions

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.

8.1.1 SCSI hard disk drives

The SCSI hard disks which can be ordered for the server are supplied already mounted in the hard disk carriers. The slide-in modules are equipped with a status and an error indicator. Unequipped installation bays are covered with a blank insert.
