Resolution

First attempt to reset the controller through the Powervault Manager GUI.

1. Log in as admin in Powervault Manager
2. Click System on the left hand panel
3. Click the Action button
4. Click Reset System
5. Select "Restart" for Operation
6. For "Controller Type" choose Storage
7. Select either Controller A or B (whichever is causing problems)
8. Click OK

The controller can take anywhere from 5-10 minutes to fully reset.  If the controller reset does not solve the problem, open a case with technical support and be prepared with the storage logs.  Most likely the controller will need to be replaced.
