Hard Disk Drive Lamp - NEC EXP200 User Manual

Hard Disk Drive Lamp

The optional hot-swap SCSI hard disk drive bay can contain four 1-inch height SCSI hard disk
drives. Each hard disk drive has a DISK lamp on its front panel.
The DISK lamp indicates the drive status as follows.
Lighting green
The hard disk drive is installed and powered on.
Blinking green
Indicates that the hard disk drive is accessed.
Lighting amber
Indicates that the installed hard disk drive is defected.
NOTE:
(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.)
Slowly blinking amber
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 lamp goes on green when the rebuild is terminated normally. The lamp goes on amber
if the rebuild fails.
IMPORTANT:
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.
