Recognizing hard drive failure
In an HP storage system, a steadily glowing Fault LED indicates that that drive
has failed. When a drive is configured as part of an array and attached to a
powered up controller, the status of the drive can be determined from the
illumination pattern of the controller LEDs (on page
20 ).
Other means by which hard drive failure is revealed are:
• The amber LED on the front of a storage system illuminates if failed drives
are inside. (However, this LED also illuminates when other problems occur,
such as when a blower fails, a redundant power supply fails, or the system
overheats.)
• A controller display message lists failed drives whenever the system is
restarted, as long as the controller detects at least one functional drive.
• ACU represents failed drives with a distinctive icon.
• HP SIM can detect failed drives remotely across a network. (For more
information about HP SIM, refer to the documentation on the Management
CD.)
