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 p riority over other 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 LC D, but not in as much detail.
Whenever p ossible, refer to HP Command View EVA for fault information.

either a Termination Event display or an Event display. These displays are similar, but not identical.

• The Termination Event display includes a Code Flag field; it does not include the EIP Type field.
• The Event display includes an EIP type field; it does not include a Code Flag fi eld.
• The Event display includes a Correctiv e Action Code field.
