HP StorageWorks XP Cluster Extension Software Administrator Guide (T1656-96035, April 2010)

you will see the customized XP Cluster Extension Parameters tab. The customized tab is displayed
because the resource extension DLL is registered by default on Windows Server 2003 cluster
nodes, which prevents you from configuring the XP Cluster Extension resource from a remote
management station.
If you need to configure an XP Cluster Extension resource remotely for a Windows Server 2003-
based cluster, unregister clxmscsex.dll from the cluster node, which allows you to remotely
configure an XP Cluster Extension resource using the standard Microsoft Properties tab. Use the
command cluster /UNREGADMINEXT:clxmscsex.dll to unregister the DLL.
NOTE:
Configuring XP Cluster Extension resources by using Cluster Administrator from a remote
management station is supported using only the standard Microsoft Properties tab. Do not try to
use the customized XP Cluster Extension Parameters tab for this purpose.
• When you configure XP Cluster Extension resource properties from a remote management station
through the Cluster Administrator, 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 MSCS
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.
