HP XP Cluster Extension Software Administrator Guide

occur if you have a cluster with both Server Core or Hyper-V Server and Windows Server
2008/2008 R2/2012 cluster nodes.
Powershell cmdlets can also be used instead of cluster.exe to unregister clxmscsex.dll.
For more information, see Microsoft documentation.
• When you configure XP Cluster Extension resource properties from a remote management
station through the MMC, which uses the standard Microsoft Properties tab, the properties
you enter are not validated, so you must enter the property values accurately, and verify them
against the XP Cluster Extension documentation.
System resources
Monitor the system resources on a regular basis as part of Windows administration. If any system
resource usage by the cluster service is reaching maximum levels, stop and then restart the cluster
service. This action automatically fails over the resources and resets system resources. See the
MSFC documentation for information about how to stop a cluster service.
An alternate method is to manually move all resources to another node in the cluster before stopping
the cluster service. After all resources are successfully moved to another node, stop and then restart
the cluster service; then, manually move back all resources.
Logs
If the XP Cluster Extension log files need to be cleared and reset (for example, to reduce disk space
usage), you can delete the files. XP Cluster Extension automatically creates new log files.
TIP: Archive the log files before deleting them.
Hyper-V Live Migration log entries
In the XP Cluster Extension log file (clxmscs.log), live migration messages include the prefix
CLX_LM to help you differentiate live migration issues from XP Cluster Extension log messages.
For example:
[10/12/09 20:13:02][2136][CLX_LM: CLXVMDISK04-App01][INFO] CLX detected
that Live Migration for VM "Virtual Machine VM04" has begun.
[10/12/09 20:13:02][2136][CLX_LM: CLXVMDISK04-App01][INFO] CLX started
gathering VM "Virtual Machine VM04" specific storage information.
