HP XP Cluster Extension Software Installation Guide (5697-2449, July 2013)

2. Registration of resource extension DLL must not be performed on Server Core environments.
Check whether the cluster administrator extension DLL is registered with MSFC to provide the
Cluster Administrator GUI functionality by entering:
cluster resourcetype "Cluster Extension XP" /PROPERTIES
If the resource extension DLL is registered, the output includes the following information:
Cluster Extension XP AdminExtensions {45486A33-D4EA-11D4-9288-0060B0CCC2FD}
If the resource extension DLL is not registered:
a. Enter cluster /REGADMINEXT:clxmscsex.dll. This command must be executed
on all the cluster nodes.
b. Run the cluster resourcetype command again to verify that the DLL is now
registered. Powershell cmdlets can also be used instead of cluster.exe to perform the
same operations. For more information, see Microsoft documentation.
3. To Check if the resource extension DLL is registered, run the following command:
(Get-ClusterResourceType "Cluster Extension XP").AdminExtensions
If the resource extension DLL is registered, the output includes the GUID of the admin extension:
{45486A33-D4EA-11D4-9288-0060B0CCC2FD}
If the resource extension DLL is not registered
a. Run the command regsvr32 c:\windows\system32\clxmscsex.dll. Run this
command from all the cluster nodes.
b. Run the command on the powerShell environment
(Get-ClusterResourceType "Cluster Extension XP").AdminExtensions
= "{45486A33-D4EA-11D4-9288-0060B0CCC2FD}"
This command should be executed only from one of the cluster nodes.
Unregistering the resource type and resource extension DLL manually
Enter the following command to unregister the resource extension DLL:
cluster /UNREGADMINEXT:clxmscsex.dll
Enter the following command to unregister the resource type:
cluster resourcetype "Cluster Extension XP" /delete
Powershell cmdlets can also be used to perform the same operations. Enter the following commands
to unregister the resource extension DLL:
1. Run the command regsvr32 /u c:\windows\system32\clxmscsex.dll. This must
be executed on all the cluster nodes.
2. Run the command on the PowerShell Environment (Get-ClusterResourceType "Cluster
Extension XP").AdminExtensions = "". This must be executed only from one of the
cluster nodes.
Enter the following command to unregister the resource type from one of the cluster nodes.
Remove-ClusterResourceType -Name "Cluster Extension XP"
NOTE: On Windows Server 2012, another cluster resource of type "Cluster Extension XP for
VM Management" is also created. If you experience issues in registration and unregistration of
this resource type, follow the steps mentioned in “Registering the resource type and resource
extension DLL manually” (page 19) and “Unregistering the resource type and resource extension
DLL manually” (page 20) to overcome the issues.
