General Description 2-13
Hard Disk Lamp
The disk lamp mounted in the 3.5-inch disk bay indicates the following depending on the status:
„
Flashing (green)
The lamp indicates that the hard disk is accessed.
„
On (amber)
The lamp indicates a failure of a hard disk mounted in disk array configuration.
NOTE: Even if one of the hard disks fails in disk array configuration
(RAID1 or RAID5), the server can continue operation. However,
replace the disk as soon as possible, and perform reconstruction
(rebuild) processing. (The failing disk can be replaced in hot swap
mode.)
„
Flashing switching back and forth between green and amber
The lamp indicates that reconstruction (rebuild) processing is being performed for the
hard disk. (This flashing does not indicate a failure.) When a failing hard disk is
replaced in disk array configuration, the system automatically rebuilds the data. (Auto-
rebuild function) The lamp switches back and forth between green and amber during
rebuild processing.
The lamp goes off when the rebuild processing has terminated. It turns amber when the
rebuild processing fails.
IMPORTANT: If the server is turned off during rebuild processing, the
processing is stopped. Restart the server, mount the new hard disk in
hot swap mode, and then perform rebuild processing again. Observe
the following notes on using the auto-rebuild function.
„
Do not turn the power off. (Once the power is turned off, the auto-
build function does not start.)
„
Let 90 seconds or more pass between when dismounting a failing
hard disk and when mounting the new one.
„
Do not replace a failing hard disk while rebuild processing is being
performed for another hard disk.
