If the hard disk fails in a single hard disk configuration, a system shutdown is either imminent,
in progress, or complete. Replace the hard disk (see
“Replacing a hard disk in the hard disk
).
Monitoring the RAID LEDs
Use this procedure to determine the current operational state of the RAID hard disks and disk
mirroring operation (see
). The RAID Status LEDs are visible only for systems
equipped with the RAID configuration. Three LEDs are located on the bezel face of the BCM400
advanced function tray or on the hard disk access panel at the rear of the BCM200 main unit.
The RAID LEDs indicate monitoring of the following:
•
Primary master hard disk activity
•
Mirror hard disk activity
•
RAID disk mirroring status activity

To determine RAID status
1
Examine the Primary and Mirror LEDs on the BCM400 advanced function tray faceplate.
Alternatively, examine the hard disk cover access panel on the rear of the BCM200. Use
to interpret the operational state of the RAID primary master and mirror master hard
disks and perform any associated maintenance action if required.
