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.)
