8.2.1Replacing SCSI hard disk drives

VCAUTION!

Never pull out a hard disk drive during operation if you are not sure that the hard disk drive is operated on a RAID controller and is part of a disk array that operated in the mode RAID Level 1or 5.

A defective drive as part in a disk array has to be replaced during operation only.

The hard disk drives which can be ordered for the server are supplied already mounted in the hard disk drive slide-in modules. A hard disk in the hard disk drive slide-in module can only be replaced by a service technician.

If you want to swap a SCSI hard disk drives during operation, proceed as follows:

If you wish to insert a hard disk drive in an empty bay, then the dummy module must be removed from this bay beforehand.

Installing/removing the dummy module is performed in the same manner of the hard disk drives.
