Identifying a Failed Hard Disk Drive
Before a hard disk drive can be replaced you must identify which drive has
failed. This section details how to identify a failed hard disk drive in Lucent™
I
NTUITY™ systems with two hard disk drives.
NOTE:
If your system is configured with only one hard disk drive, see ‘‘Recovering
from a Hard Disk Drive 0 Failure in a Single Disk System’’ below for the
procedure.
Identifying a Hard Disk Drive 0 Failure in a
Single Disk System
Because Hard Disk Drive 0 contains the only copy of the operating software in a
nonmirrored system, a failure of this drive will result in a complete failure of the
system. If this occurs you will not be able to reboot the system. See ‘‘Recovering
from a Hard Disk Drive 0 Failure in a Single Disk System’’ below for the
replacement procedure.
Identifying a Hard Disk Drive Failure in a
Mirrored System
In a mirrored system both hard disk drives contain the same information. As a
result, if either hard disk drive fails the other drive will continue to operate the
system. There will be no noticeable difference in service. A hard disk drive failure
will be identified by checking the maintenance log.
NOTE:
If the following procedure can not be performed, and the failure is causing
several message to appear on the console, it is likely that Hard Disk Drive 0
has failed.
