HP 3PAR StoreServ Cluster Extension Software Administrator Guide (5697-2442, July 2013)

5 Troubleshooting
To troubleshoot problems with HP 3PAR StoreServ Cluster Extension, one must understand HP 3PAR
Remote Copy environments. See the Remote Copy User's Guide for more information on Remote
Copy configuration and volume group states. See the HP 3PAR StoreServ Cluster Extension log for
any cluster specific information. However, it always keeps its own log files in its default log location.
CAUTION: HP 3PAR StoreServ Cluster Extension cannot handle Remote Copy volume group
states automatically and correctly, if they result from manual manipulations (either through HP 3PAR
GUI or CLI or through any other means).

The following logs are available for troubleshooting:
• Event logs
• Cluster related log messages logged by Windows Cluster (%windir%\cluster\reports\
