not resolved by using the management GUI. In those situations, review the symptoms and follow the

actions that are provided here.

Unless you are unable to detect a newly installed enclosure, problems on expansion enclosures are

Select the recommended alert, or any other alert, and run the fix procedure. The fix procedure steps you

through the process of troubleshooting and correcting the problem. The fix procedure displays

information that is relevant to the problem and provides various options to correct the problem. Where it

is possible, the fix procedure runs the commands that are required to reconfigure the system.

drive showing a fault. In this case, the drive must be replaced and reconfiguration must be performed.

The fix procedure performs the reconfiguration for you.
