Instruction Manual

C C ontroller fault management
This appendix describes how the controller displays events and termination event information. Termination
event information is disp layed on the LCD. The HP Command View EVA GUI enables you to view
controller events. This appendix also discusses how to identify and correct problems.
Once you create a storage system, as described in Chapter 2, “Setting Up a Controller Pair Using the
OCP,” an error condition message has priority ov er other controller display s.
The H P Command View EVA GUI provides detailed descriptions of the storage system error c onditions,
or faults. The Fault Management displays provide similar information on the LCD, b ut not in as much
detail. Whenever possible, refer to the GUI for fault information.
Using the HP Command View EVA GUI
The HP Command View EVA GUI display provides detailed information about each event affecting
system operation in either a Termination Event display or an Event display. These displays are similar,
but not iden
tical.
GUI termination event display
A problem that generates the Termination Event display prevents the system from performing a specific
function or process. You can use the information in this display (see GUI Termination Event Display)
to diagnose and correct the problem.
NOTE:
The major differences between the Termination Event display and the Event display are:
• The Termination Event display includes a Code Flag field; it does not include the EIP Type field.
• The Event di splay includes an EIP type field; it does not include a Code Flag field.
• The Event display includes a Corrective Action Code field.
