Recognizing disk drive failure
In an HP enclosure, a steadily glowing fault LED indicates that a drive has failed.
Other indications of failed disk drives are as follows:
• ACU represents failed drives with a distinctive icon.
• HP SIM can detect failed drives remotely across a network. (For more information about HP SIM,
see the documentation on the Management CD.)
• ADU lists all failed drives.
