System expansions | SCSI hard disk drives |
If you want to swap a SCSI hard disk drives during operation, proceed as follows:
ÊPull the hard disk drive which is indicated as defective out a few centimeters.
ÊWait at least 60 seconds. This is necessary so that the RAID controller can detect that a hard disk drive has been pulled out and the hard disk drive has time to stop turning.
ÊPull the hard disk drive all the way out.
ÊInsert the new hard disk drive.
If a hard disk drive has been removed and no new drive is installed in its place, then install a dummy cover in the empty bay. Make sure that the dummy cover engages properly in the bay.
The SCSI IDs of the hard disk drive
The following applies if SCSI hard disk drives are operated on a RAID controller:
–RAID level 0
Rebuild is not possible. If a hard disk drive fails, its data is lost.
–RAID level 1 without standby hard disk drive
Rebuild on the new disk is carried out automatically when the old disk is swapped.
–RAID level 1 with standby hard disk drive
A standby hard disk drive is automatically enabled as a replacement for the defective hard disk drive and the data of the defective disk is rebuilt on the standby disk.
ÊRead the documentation for the new hard disk drive.
