DXi4700 Hard Drive Carrier Indicators
Each DXi4700 drive carrier in the Node module has two LED indicators (see Figure 29 below):
LED Indicator Activity
Drive activity indicator (green) l Flashing - Indicates hard disk drive activity.
Drive status indicator (green and amber) l Off - Drive ready for insertion or removal
Note: The drive status indicator remains off until
all drives are initialized after system power is
applied. Drives are not ready for insertion or
removal during this time.
l Blinks green two times per second - Identify
drive/preparing for removal
l Blinks green, amber, and off - Drive predicted
failure
l Blinks amber four times per second - Drive failed
l Blinks green slowly - Drive rebuilding
l Steady green - Drive online
l Blinks green three seconds, amber three
seconds, and off six seconds - Rebuild aborted
Note: If a drive fails, you will be notified by a service ticket in the remote management console (see
Service Tickets on page 183).
Caution: Do not remove a drive that has not failed. Instead, only remove a drive that has failed. If you
accidentally remove a good drive, wait 30 seconds before reinserting the drive.
