This section explains how to address problems like hardware failures that occur in a system.
Basic Procedure
The following procedure is used to confirm and resolve problems using the ROR console:
Confirm the Existence of a Problem
For the confirmation method, refer to "11.2 Resource Status" and "A.3 Status Panel" in the "User's Guide for Infrastructure Administrators (Resource Management) CE".
Check the Event Log
Use the event log to check the device where the error occurred and the content of the event.
In some cases, a single problem can cause a series of events, so search back through past events to find events with dates that are close together.
Check the Status of Resources
From the resource tree, open the resource where the problem occurred and look for any affected chassis, physical servers, LAN switches, physical OS's, VM hosts, or VM guests.
If Auto-Recovery has been enabled for a physical OS or VM host, it will be automatically switched over with a spare server. If Auto-Recovery has not been enabled, server switchover can still be performed manually as long as a spare server has been designated.
For server switchover, refer to "4.2 Switchover" in the "Operation Guide VE".
Perform Detailed Investigation and Recovery
From the [Resource Details] tab of the failed resource, launch the external management software to investigate the precise cause of the problem.
When no management software is available, confirm with the maintenance staff of the failed resource to investigate the problem.
Once this is done, perform the necessary maintenance work on any faulty hardware identified.
If a server hardware failure requires replacing a managed server, carry out the replacement operation as described in "9.3.2 Replacing Servers".
Perform Post-recovery Verification
Following recovery, confirm that there are no more icons indicating problems on the ROR console.
