string and integer value are displayed. For the CLI, a return code is displayed. For more information,
see “CLI commands” (page 66).
Log files
Log files assist you in locating and identifying problems. Timestamps, component IDs, and message
IDs are included.
• HP 3PAR StoreServ Cluster Extension-related messages are logged by MSFC to the file
cluster.log in the location %windir%\Cluster\Reports.
• For each system, HP 3PAR StoreServ Cluster Extension keeps its own log file in its default log
location.
Log locationLog file
%HPCLX_3PAR_PATH%\logclxmscs.log
%HPCLX_3PAR_PATH%\logVMClxMscs.log (For VM Management on
Windows Server 2012/2012 R2 only)
%HPCLX_3PAR_PATH%\logCLXCmdlet.log
NOTE: For VM management only: If you change the LogLevel, the new LogLevel is
effective only after the cluster service restarts on the cluster node where you are modifying the
LogLevel.
• HP 3PAR StoreServ Cluster Extension messages can also be found in the following:
◦ MSFC log file [%windir\cluster\reports\cluster.log]
Always disable automatic service or application failover when merging or resynchronizing
Remote Copy volume groups. A failure of the resynchronization source while resynchronizing
can lead to noncurrent data on the resynchronization target.
Start errors
• Generic startup or initialization logic errors can occur when the path to the HP 3PAR StoreServ
Cluster Extension binaries has not been set in the PATH environment variable and the processes
(for example the cluster service) have not recognized the %HPCLX_3PAR_PATH% variable.
To fix this problem, restart the cluster service.
• If the required components of HP 3PAR StoreServ Cluster Extension are not available, a file
(clxlog.log ) is generated that can be used for troubleshooting. The file is usually in the
working directory of the operating system (%SYSTEMROOT%).
• HP 3PAR StoreServ Cluster Extension returns a local error if any of the following occurs:
HP 3PAR StoreServ Cluster Extension does not find the user configuration file for
clx3PARrun in the correct directory location.
◦
◦ An error occurs after initialization.
Failover error handling
Windows Cluster automatically fails over resource groups if the system where resource group is
running on becomes unavailable. This is part of the cluster functionality. Also, this means that if a
problem occurs with the HP 3PAR StoreServ Storage, a resource group online process will be
stopped. The behavior of HP 3PAR StoreServ Cluster Extension is highly configurable. Depending
