Interpreting disk module LEDs
The disk module LEDs and the 7-segment display on the back of the RAID
Controllers are used to indicate system status. The following table describes how to
interpret the disk module LED behavior and rear panel 7-segment display for various
conditions.
LEDs a
a. If the disk access LED is unlit at any point, it indicates one of the colored LEDs has failed. The access
LED should display some color at all times.
7-Segment
Display Meaning
All drives are green,
non-blinking chassis address Drives are behaving normally— no disk access
in progress
b
b. A RAID LUN may fail without providing blue LED indication, however, NetCentral alerts can provide
this information.
All drives are green, rapid
blinking chassis address Disk I/O in progress
One drive is blue chassis address Drive has been identified using the GVG Disk
Utility.
F Drive is failed.
One drive is alternating blue/
green, rapid blinking chassis address Disk I/O in progress and the drive has been
identified using the GVG Disk Utility.
One drive is green/red (orange) Drive itself has determined it is bad, or the
midplane has failed.
One drive is blue/red (purple) Drive itself has determined it is bad and the drive
has been identified using the GVG Disk Utility.
All drives are blue/red (purple),
slow blink A failure affecting drives or midplane has
occurred. Consult NetCentral for failure
information.
One drive is white (red, green,
and blue LEDs active) The drive is off the Fibre Channel loop, possibly
due to a drive or midplane failure, and the drive
has been identified using the GVG Disk Utility,
or the RAID array has gone critical.
