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 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
Drive has been identified using the GVG Disk
Utility.
F
Drive is failed.
One drive is red
Drive itself has determined it is bad.
All drives are alternating blue/
green at two second intervals
F and chassis
address
(alternating)
Something (such as a power supply, blower, etc.)
in the array failed.
RAID only: All drives are blue
for 5 minutes, then green for 30
seconds
Failed drive in the array needs to be replaced.
RAID only: All drives are blue
System-wide failure has occurred. Do not
remove a drive. Call Grass Valley Group
Support as described in page 13.
One drive is green while all other
drives are blinking blue.
