Hard Drive Carrier Indicators
Each hard drive carrier has two LED indicators (see Figure 8 ):
• Drive activity indicator (green)
• Flashing - Indicates hard disk drive activity.
• Drive failure indicator (green and amber)
• Off - Drive ready for insertion or removal
Note: The drive status indicator remains off until all hard
drives are initialized after system power is applied.
Drives are not ready for insertion or removal during this
time.
• Blinks green two times per second - Identify drive/preparing
for removal
• Blinks green, amber, and off - Drive predicted failure
• Blinks amber four times per second - Drive failed
• Blinks green slowly - Drive rebuilding
• Steady green - Drive online
• Blinks green three seconds, off three seconds, amber three
seconds, and off three seconds - Rebuild aborted
Note:
If a drive fails, you will be notified by an admin alert in the
remote management pages (see Admin Alerts on
page 125).
Caution: All drives are hot swappable. When replacing drives,
never remove more than one drive at a time from a
RAID set. After removing a drive, first wait one minute.
Then insert a working drive and wait for the RAID set to
finish rebuilding (red indicator light is off) before
removing another drive. For information about RAID
sets, see Supported RAID Configurations on page 10.
