Chapter 2 NAS Head 2-75
A drive has failed how do I replace it?
Failed drives are usually evident by the following:
Red light is on the drive.
Log will display “Failed drive at slot #”.
Diagnostic email will list drive as failed.
LUN will be reported as degraded in the log and in the diagnostic email.
Controller alarm may be beeping.
Some or all of these symptoms may exist. The process is the same regardless of how
the failed drive is reporting.
This functionality is only available through the StorEdge Web Admin.
1. To access these settings, log in, and navigate to RAID/Manage RAID.
The screen may take several minutes to display, as the StorEdge must scan the RAID
subsystem for configuration data.
This screen displays the drives, RAID sets and LUN configuration.
Functional drives have a green LED displayed beside them. The failed drive will
have a red LED. Replace the failed drive.
After a few minutes, the display will change. The replaced drive will display a
yellow LED, with status “new drive added not configured”.
RMV LUN, ADD LUN, RMV HS and Add HS buttons will be grayed out.
2. Select the Rebuild button and the system will start a LUN rebuild.
The time for completion is dependent on drive size, system load and LUN size. The
average is approximately 2-3 hours to complete a rebuild.
Alarm will continue to beep until rebuild is complete
When complete, the LED displayed beside the drive will change to green, with a
status of “online”.
Log message: LUN critical.
Email alert: LUN critical.
This is an indication that the system has a failure in the disk subsystem, and that
there is no spare drive. The term “Critical” is used because another drive failure
would result in failure of the LUN and all the data contained there.
Verify the following:
Are there any red lights on any hard drive in StorEdge?
