Cluster /UNREGADMINEXTclx3PARmscsex.dll

To check if the resource extension DLL is registered, run the following command:

(Get-ClusterResourceType "Cluster Extension 3PAR").AdminExtensions

If the resource extension DLL is registered, the output will show the GUID of the admin extension as shown

{C977EFB9-B640-4E6C-9473-ECE586EC2074}

If resource extension DLL is not registered

1.Run the command regsvr32 c:\windows\system32\clx3parmscsex.dll. Run this command on all the cluster nodes.

2.Run the command on the PowerShell environment:

(Get-ClusterResourceType "Cluster Extension 3PAR").AdminExtensions = "{C977EFB9-B640-4E6C-9473-ECE586EC2074}"

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:clx3PARmscsex.dll

Enter the following command to unregister the resource type:

cluster resourcetype "Cluster Extension 3PAR" /delete

Using the PowerShell

Enter the following command to unregister the resource extension DLL:

1.Run the command regsvr32 /u c:\windows\system32\clx3parmscsex.dll. This should be executed on all the cluster nodes.

2.Run the command on the PowerShell Environment (Get-ClusterResourceType "Cluster Extension 3PAR").AdminExtensions = ""

This should be executed only from one of the cluster nodes.

Enter the command to unregister the resource type from one of the cluster nodes.

Remove-ClusterResourceType -Name "Cluster Extension 3PAR"

NOTE: On Windows Server 2012, another cluster resource of type "Cluster Extension 3PAR for VM Management" is also created. If an user experiences 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.

Registering the CLX PowerShell Cmdlet DLL manually [Windows Server 2012 only]

If a problem occurs during installation, execute the following commands from the command line on all the cluster nodes to register the PowerShell Cmdlets DLL.

Check if Cmdlet is registered or not. Launch PowerShell Window. Run the Command

Get-PSSnapin -Registered

If the Cmdlet is registered then the following output will be displayed:

Name : CLX3PARCmdletsSnapin

PSVersion : 3.0

Description : This PowerShell SnapIn provides cmdlets for helping the user manage CLX 3PAR with Microsoft Windows PowerShell.

Cluster Software specifications

HP Cluster Software is a robust solution designed to enhance the reliability, availability, and scalability of computing environments in enterprise settings. This software is instrumental in managing clusters of servers, providing a unified framework that allows for efficient resource management, workload distribution, and high availability.

One of the main features of HP Cluster Software is its ability to deliver high availability through failover mechanisms. In the event of a hardware or software failure, the software automatically shifts workloads from the affected node to a standby node within the cluster, minimizing downtime. This feature is critical for organizations that require continuous access to their data and applications.

Scalability is another significant characteristic of HP Cluster Software. Organizations can easily add or remove nodes from the cluster without disrupting ongoing operations. This flexibility ensures that enterprises can adapt to changing workloads and resource demands efficiently, making it suitable for environments ranging from small businesses to large data centers.

Load balancing is a key technology employed by HP Cluster Software. It intelligently distributes workloads across the available nodes, optimizing resource utilization and ensuring that no single server is overwhelmed. By balancing the load, organizations can achieve better performance and enhance the response times of applications, which are essential for user satisfaction.

HP Cluster Software supports various clustering topologies, including active-active and active-passive configurations. This versatility allows organizations to choose the architecture that best fits their operational requirements. Additionally, the software integrates seamlessly with various HP and third-party hardware and software solutions, thus providing a holistic environment for managing IT resources.

Moreover, HP Cluster Software offers centralized management tools that simplify cluster administration. Administrators can monitor cluster performance, manage workloads, and configure settings all from a single interface. This ease of use reduces the complexity often associated with managing large clusters and empowers IT teams to respond rapidly to issues.

In summary, HP Cluster Software is an essential tool for organizations looking to enhance their IT infrastructure's availability, reliability, and performance. With its failover capabilities, scalability options, load balancing technology, and centralized management features, it stands out as a comprehensive solution for modern computing challenges.
