HP XP Cluster Extension Software Administrator Guide

Remote management of HP XP Cluster Extension resources in a cluster (Windows
Server 2008/2008 R2/2012/2012 R2)
You can use the MMC with Failover Cluster Management to manage clusters and configure HP
XP Cluster Extension resources. Note the following when configuring HP XP Cluster Extension
resources by using the MMC from a remote management station:
• When you use the MMC to remotely configure HP XP Cluster Extension resource properties
in a Server Core or Hyper-V Server cluster node, the Failover Cluster Management GUI on
the remote management station displays the standard Microsoft Properties tab instead of the
customized HP XP Cluster Extension HP XP CLX Settings tab. For more information about the
Properties tab, see “Setting HP XP Cluster Extension resource properties using the MMC”
(page 32).
• When you install HP XP Cluster Extension into a Windows Server 2008/2008 R2/2012/
2012 R2 environment, the resource extension DLL is registered by default, which prevents you
from configuring HP XP Cluster Extension resource from a remote management station. If you
need to remotely configure HP XP Cluster Extension resource in a Windows Server 2008/2008
R2/2012/2012 R2-based cluster, unregister clxmscsex.dll from the cluster node, which
allows you to configure the HP XP Cluster Extension resource using the standard Microsoft
Properties tab. Use the command cluster /UNREGADMINEXT:clxmscsex.dll to unregister
the DLL.
Powershell Cmdlets can also be used instead of cluster.exe to unregister clxmscsex.dll.
For more information, see Microsoft documentation.
CAUTION: Configuring HP XP Cluster Extension resources using the MMC from a remote
management station is supported using only the standard Microsoft Properties tab. Do not try
to use the customized HP XP Cluster Extension HP XP CLX Settings tab for this purpose.
• If you see the customized HP XP Cluster Extension HP XP CLX Settings tab when you try to
configure HP XP Cluster Extension resource from a remote management station using the MMC,
you must unregister clxmscsex.dll from the cluster node. Use the command cluster
/UNREGADMINEXT:clxmscsex.dll to unregister the DLL. Unregistering the DLL allows you
to configure the resource using the standard Microsoft Properties tab. This situation might
occur if you have a cluster with both Server Core or Hyper-V Server and Windows Server
2008/2008 R2/2012/2012 R2 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 HP 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 HP XP Cluster Extension documentation.
• On Windows Server 2012/2012 R2 Failover Cluster, you cannot use the MMC to remotely
configure the CLX resource on which the CSV disk is dependent. On a Windows 2012/2012
R2 Server Core system, you must use the XP Resource Configuration Tool
(ClxXpResConfig.exe) to configure the CLX resource for the CSV disk. On a non-server
core Windows Server 2012/2012 R2 system, you can use the CLX resource configuration
utility integrated with the CSV cluster resource in the Failover Cluster, or use the XP Resource
Configuration Tool (ClxXpResConfig.exe) to configure the CLX resource for the CSV disk.
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
