Hard Disk Drive LED
Each indication of the DISK LED on a hard disk drive bay has a different meaning.
Blinks in green: the hard disk drive is being accessed.
Illuminates in amber: the hard disk drive has failed.
Illuminates in green and amber in turn: the hard disk drive reconfiguration (rebuild) is ongoing. This
does not indicate the hard disk drive has a problem.
When the rebuilding is completed the LED goes off. If the rebuilding fails, the LED illuminates in
amber.
Blinks in amber: the hard disk drive has a mirror volume for which redundancy is not achieved (i.e.
mirrored configuration is in the degenerated mode).
