HP EVA Cluster Extension Software Administrator Guide (5697-2445, July 2013)

5 Troubleshooting
To troubleshoot problems with EVA Cluster Extension, you must understand HP EVA Continuous
Access environments. See the HP EVA Continuous Access and HP EVA SMI-S documentation before
assuming that a problem has been caused by EVA Cluster Extension.
Changing the EVA SMI-S user name and password
If the HP P6000 SMI-S user name or password is changed through the P6000 Command View
GUI or any other method, you must change the information in the EVA Cluster Extension.
For Windows Server 2008/2008 R2/2012, see “Starting the HP EVA Cluster Extension
configuration tool” (page 17).
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 %ProgramFiles%\Hewlett-Packard\Cluster
Extension EVA\log\ directory
For example, if you need to clear and reset the log file 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
local error
to enable disk access, or the misconfiguration of the storage
system environment.
Prohibits an application service startup on any system in
the local data center. This error is returned if the disk state
data center error
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.
Returned if the configuration or the disk state do not allow
an automatic application service startup process. Manual
global error
intervention is required in such cases. MSCS does not allow
cluster-wide or data-center-wide disabling of resources.
This is local error behavior.
When EVA Cluster Extension is integrated into the cluster software, an error message string and
integer value are displayed. For the CLI, a return code is displayed. For more information, see
Command line utilities (page 70).
Log files
Log files assist you in locating and identifying problems. Timestamps, component IDs, and message
IDs are included.
• EVA Cluster Extension-related messages are logged by MSCS to the file %ClusterLog%\
cluster.log.
• For VM Management on Windows Server 2012 only, the VMClxMscs.log file resides in:
%ProgramFiles%\Hewlett-Packard\Cluster Extension EVA\log\
