C Controller fault management
This app endix describes how the controller displays events and termination event information. Termination
event information is displayed on the LCD. HP Command View EVA enables you to view controller events.
This appendix also discusses how to identify and correct problems.
Once you create a storage system, an error condition message has priority over o ther controller displays.
HP Command View EVA provides detailed descriptions of the storage system error cond itions, or faults.
The Fault Management displays provide similar information on the LCD, but not in as much detail.
Whenever possible, refer to HP Command View EVA for fault information.
