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

DescriptionError return code
Returned if the configuration or the disk state do not allow an automatic application
service startup process. Manual intervention is required in such cases. MSCS does not
allow cluster-wide or data-center-wide disabling of resources. This is local error
behavior.
global error
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” on page 91.
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.
• EVA Cluster Extension-related messages are logged by RHCS and SLE HA for each cluster resource
to the file /var/log/messages.
• For each system, EVA Cluster Extension keeps its own log file in its default log location.

CAUTION:
EVA Cluster Extension is not able to handle DR group states automatically and correctly when
they result from manual intervention or modifications to the DR group states.
Always disable automatic service or application/package failover when merging or resynchron-
izing DR groups. A failure of the resynchronization source while resynchronizing can lead to non-
current data on the resynchronization target.
The resynchronization process copies data in transactional order, which means that you could start
your application with this data but it might be older than the source.
Start errors
• In Windows, generic startup or initialization logic errors can occur when the path to the EVA
Cluster Extension binaries has not been set in the PATH environment variable and the processes
