Hard Disk Drive Lamp (Disk Lamp) - NEC N8100-1220F User Manual

Hard Disk Drive Lamp (DISK Lamp)

The disk lamp on the 3.5-inch disk bay has different meanings depending on the display status.
Lighting green
The hard disk is installed and powered on.
Blinking green
Indicates that the hard disk is accessed.
Lighting amber
Indicates that the installed hard disk is defected in the disk array configuration.
NOTE:
(RAID1/RAID5 or RAID0+1), a single failed hard disk does not affect
the operation of the server. However, it is recommended to replace the
failed hard disk and auto-rebuild (reconfigure) the hard disks as soon as
possible. (You can hot-swap such a failed hard disk.)
Alternate lighting green or amber
Indicates that the hard disk is being rebuilt (this status is not a failure). If the defected
hard disk is replaced with a new one in the disk array configuration, the data is
automatically rebuilt (auto rebuild function). During the rebuild operation, the lamp is lit
green or amber alternatively.
The lamp goes off 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, 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 disks, the auto-rebuild feature will not start.)
When you removed a hard disk, wait at least 90 seconds before
installing the hard disk back again.
Do not replace another hard disk while rebuilding is in progress.
