Rebuilding a defunct drive

A physical drive is defunct when there is a loss of communication between the

controller and the physical drive.

This can be caused by any of the following:

•

An improperly connected cable, physical drive, or controller

•

A loss of power to a drive

•

A defective cable, backplane, physical drive or controller

In each case, the communication problem needs to be resolved, and then a rebuild

operation is required to reconstruct the data for the device in its disk array.

The

ServeRAID controllers can reconstruct RAID level-1 and RAID level-5 logical drives,

but they cannot reconstruct data stored in RAID level-0 logical drives.

Explanation:

Online/rebuild and ready/standby drives are not responding, a drive

was found at the incorrect SCSI ID, and unidentified drives were found.

Action:

Press F4, F5, F6, or F10.

Explanation:

Online/rebuild, ready/standby, and hot-spare/standby hot-spare

drives are not responding, and unidentified drives were found.

Action:

Press F4, F5, or F10.

Explanation:

Online/rebuild, ready/standby, and hot-spare/standby hot-spare

drives are not responding, a drive was found at the incorrect SCSI ID, and

unidentified drives were found.

Action:

Press F4, F5, F6, or F10.

Explanation:

No error occurred.

Action:

No action is required.

Explanation:

Hot-spare/standby hot-spare drives are not responding.

Action:

Press F4, F5, or F10.

Explanation:

Ready/standby drives are not responding.

Action:

Press F4, F5, or F10.

Explanation:

Hot-spare/standby hot-spare and ready/standby drives are not

responding.

Action:

Press F4, F5, or F10.

Explanation:

No error occurred.

Action:

No action is required.

Explanation:

Hot-spare/standby hot-spare drives are not responding.

Action:

Press F4, F5, or F10.

Explanation:

Ready/standby drives are not responding.

Action:

Press F4, F5, or F10.

Explanation:

Hot-spare/standby hot-spare and ready/standby drives are not

responding.

Action:

Press F4, F5, or F10.
