Respond.to.a.Critical.RAID.Volume
How the unit responds to a critical RAID Volume depends on the RAID level of your Volume and whether you have a
spare drive available:
For RAID.1 Volumes, if a spare drive is available, the RAID Volume will begin rebuilding itself automatically.
For RAID.1 Volumes, when no spare drive is available, you must replace the failed disk drive. The RAID Volume will begin rebuilding itself when you install the new
disk drive.
RAID.0
Volumes go offline after a disk drive failure. A
RAID.0
volume cannot be rebuilt. All data on the volume will be lost.

Be sure there is adequate air flow around the device.

Step 3: Check the fan speed.
If the fan speed is below 1800 RPM, contact Technical Support.
If any power status item is out-of-specification, contact Technical Support.
