8-6 Troubleshooting
DISK LED
The hard disk drive bay can contain three hard disk drives. Each hot-plug hard disk drive has a
DISK LED on its front panel.
The DISK LED indicates the drive status as follows.
„
Blinking green
Indicates that the hard disk drive is accessed.
„
Lighting amber
Indicates that the installed hard disk drive is defected.
NOTE:
While hard disk drives are in the RAID configuration (RAID1
or RAID5), a single failed hard disk drive does not affect the operation
of the server. However, it is recommended to replace the failed hard
disk drive and auto-rebuild (reconfigure) the hard disk drives as soon as
possible. (You can hot-swap such a failed hard disk drive.)
„
Alternate blinking amber or green
Indicates that the hard disk drive is being rebuilt (this status is not a failure). If the
defected hard disk drive is replaced with a new one in the disk array configuration, the
data is automatically rebuilt (auto rebuild function).
The LED goes off when the rebuild is terminated normally. The LED goes on amber if the
rebuild fails.
IMPORTANT:
Powering off the server aborts rebuilding. In such a
case, restart the server, hot-swap the failed hard disk drive, and restart
rebuilding. Observe the following notes to use the auto-rebuild feature.
„
Do not power off the server. (If the server is powered off before
rebuilding hard disk drives, the auto-rebuild feature will not start.)
„
When you removed a hard disk drive, wait at least 90 seconds
before installing the hard disk drive back again.
„
Do not replace another hard disk drive while rebuilding is in
progress.
