16.2 Event Description

16.2.1 Logical Drive Events

Critical

Message LG:0 Logical Drive ALERT: CHL:0 ID:132 Drive Missing

What Happens? The specified hard drive in the specified logical drive has is missing.

What to Do? The drive could have been accidentally removed or drive connection

problems occurred. Check drive connection and related enclosure

status.

Message LG: Logical Drive ALERT: CHL:0 ID:132 Drive Failure

What Happens? The specified hard drive in the specified logical drive has failed

What to Do? IF a spare is available, the subsystem will automatically start rebuild.

If there is no spare, replace the faulty drive and rebuild will be auto-

matically initiated provided that a replacement drive can be recog-

nized by the subsystem. For example, in a SCSI-based subsystem, a

manual “Scan Drive” command should be executed. In subsystems

using other types of disk drives, drive swap auto-detection should be

enabled on the drive channels.

Message LG:0 Logical Drive ALERT: Rebuild Aborted

What Happens?

Logical drive rebuild aborted. It could result from the one of the fol-

lowing reasons:

1. The rebuild has been manually canceled by a user.

2. The replacement drive used for a rebuild may have failed during

the rebuild or the drive contains immanent defects.

3. Bad blocks are encountered on another member drive during

the rebuild. (RAID 1, 3, and 5 arrays)

4. System faults occurred.

What to Do? Carefully identify and replace the faulty drive and perform logical

drive rebuild again. It is best to stop host I/Os temporarily to this log-

ical drive.
