Hard Drive Carrier Indicators
18
Each hard drive carrier has two LED indicators (see
• 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
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
