Identifying hardware faults
There are several ways the storage system can alert you to failures:
• When notified about an error by email or the Simple Management Network
Protocol (SMNP).
• When a failure is indicated by storage system LED (for example, WARNING
or ALARM LED goes on or READY LED does not go on).
To identify a failed part and recover the storage system:
Procedure
1. Check the serial number of the storage system referenced in the email
notification or SNMP alert.
2. Start the maintenance utility.
3. In the Maintenance Utility window, check the serial number of the
storage system where the error was reported. Confirm that this serial
number matches the one in step 1.
