Do not remove the drive. Removing a drive during
this process can cause data loss in non-fault-
tolerant configurations.
Either (1) the drive is part of an array being selected by
the Array Configuration Utility, (2) the Options ROMPaq

OK to replace the drive online if the array is configured
for fault tolerance and all other drives in the array are
online.
Either (1) the drive is not configured as part of an array,
(2) the drive is configured as part of an array, but a
powered-on controller is not accessing the drive, or
(3) the drive is configured as an online spare.
There are several other ways to recognize that a hard drive has failed:
•
The amber LED lights up on the front of a Compaq storage system if failed
drives are inside. (Other problems such as fan failure, redundant power supply
failure, or over-temperature conditions will also cause this LED to light up.)
•
A Power-On Self-Test (POST) message lists failed drives whenever the system is
restarted, as long as the controller detects one or more good drives. See Appendix
G for an explanation of POST messages.
•
The Array Diagnostic Utility (ADU) lists all failed drives.
•
Compaq Insight Manager can detect failed drives remotely across a network.
