HP StorageWorks EVA Cluster Extension Software Administrator Guide (T3667-96045, April 2010)

6 Troubleshooting
To troubleshoot problems with EVA Cluster Extension, you must understand HP Continuous Access
EVA environments. See the HP Continuous Access EVA and HP SMI-S EVA documentation before
assuming that a problem has been caused by EVA Cluster Extension.
Changing the SMI-S EVA user name and password
If the HP SMI-S EVA user name or password is changed through the Command View EVA GUI or any
other method, you must change the information in EVA Cluster Extension.
• For Windows Server 2003, see “clxpmu” on page 96.
• For Windows Server 2008/2008 R2, see “Starting the EVA Cluster Extension configuration
tool” on page 26.
Log facility
The logging module of EVA Cluster Extension provides log messages to the cluster software as well
as to the EVA Cluster Extension log file. The EVA Cluster Extension log file includes disk status
information and is located by default in this directory:
Windows
%ProgramFiles%\Hewlett-Packard\Cluster Extension EVA\log\
Linux
/var/opt/hpclxeva/log
If you need to clear and reset the log file, for example to reduce disk space usage, archive the log
file and then delete it. A new log file is automatically generated.
Error return codes
EVA Cluster Extension provides the following error return codes for failover operations:
DescriptionError return code
Prohibits an application service startup on the local system. This can be caused by the
inability of EVA Cluster Extension to enable disk access, or the misconfiguration of the
storage system environment.
local error
Prohibits an application service startup on any system in the local data center. This
error is returned if the disk state indicates that it makes no sense to allow any other
system connected to the same storage system to access the disks. MSCS does not allow
cluster-wide or data-center-wide disabling of resources. This is local error behavior.
data center error
