Troubleshooting Hard Drives
To troubleshoot hard drives:

Check the status of the hard drive using Storage Manager.
2
Determine the status of the hard drive indicators.
•
If the hard drive status indicator blinks amber ON for two seconds and OFF for one second, the hard drive has failed.
•
If the hard drive status indicator is not lit, proceed to the next step.
3
Check the connectors and reseat the hard drive.
CAUTION:
Perform this step only on unmanaged drives or after you confirm that the particular drive contains no user data.
The Fault LED alone is not an indication that you can safely remove the drive.
a
Remove the hard drive.
b Check the hard drive and the backplane to ensure that the connectors are not damaged.
c
Reinstall the hard drive. Make sure the hard drive makes contact with the backplane.
Troubleshooting Expansion Enclosures
To troubleshoot expansion enclosures:
1
Check the status of the expansion enclosure using Storage Manager.
2
If an expansion enclosure and/or drives are missing from the Storage Manager, you might need to check for and install Storage Center
updates to use the expansion enclosure and/or drives.
3
If an expansion enclosure firmware update fails, check the back-end cabling and ensure that redundant connections are used.
