Microsoft Windows Server 2003 Cluster Server Integration

Figure 13. Server Cluster Recovery Utility – Select Disk Resources
To complete the replacement, the new disk resource should be brought online and the drive letter
should be changed with the disk management snap-in to match the old disk resource (this is necessary
because applications typically reference files on the disk via a drive letter).
If the new physical disk resource is successfully validated, the old physical disk resource should be
deleted, as it no longer represents a real resource on the cluster.
Once the cluster is configured with the new physical disk resource, the application data can be
restored to the disk.
Debug and Log Files
In case of problems, please check the file “<File Share>\log\Server\cluster.log”.
Furthermore, debugs can be created:
1. Take the CRS service resource OBVS_MCRS offline. This will automatically stop the CRS service.
2. Edit the following lines within the trace file in the shared directory
(<File Share>\Config\Server\Options\trace):
― ranges: 1-99
― postfix: DBG
― select: <virtual host name>
3. Take the CRS service resource OBVS_MCRS online again. This will automatically start the CRS
service.
Another possibility to start the CRS service in debug mode is to add the debug options (-debug 1-99
DBG) to the start parameters of the service resource OBVS_MCRS parameter properties. This is done
within the Cluster Administrator GUI.
The debugs can be found in the “$DPHOME\tmp” directory of the active node.
