HP Cluster Software manual Adding HP 3PAR Cluster Extension resource using cluster.exe, Example

Page 22

To use 3PAR Cluster Extension, you must add an HP 3PAR Cluster Extension resource in the cluster management application. Follow one of the following ways to add CLX 3PAR Cluster Extension resource.

•Use the Failover Cluster Management GUI or cluster commands in the CLI or PowerShell Cmdlets. For instructions, see “Adding HP 3PAR Cluster Extension resource using the Failover Cluster Management GUI” (page 22) or “Adding HP 3PAR Cluster Extension resource using cluster.exe” (page 22) or “Adding HP 3PAR Cluster Extension resource using the Microsoft Failover Cluster PowerShell Cmdlets” (page 23)

•For Server Core or Hyper-V Server, use one of the following:

◦ Failover Cluster Management GUI on the remote management station

◦

◦

◦

HP 3PAR Resource Configuration Tool on CLX nodes

Cluster commands in CLX nodes

Microsoft Failover Cluster PowerShell Cmdlets.

For Server Core or Hyper-V Server also, cluster commands and PowerShell Cmdlets can be used as mentioned in the first bullet.

CAUTION: Do not use the following characters in Cluster Extension resource names: \ / : * ? "

<> . Using these characters might affect the creation of the resourcename.online file, which is used for the HP 3PAR Cluster Extension resource health check mechanism.

Adding HP 3PAR Cluster Extension resource using the Failover Cluster Management

GUI

Use the procedure in this section to add a resource using the Failover Cluster Management GUI. For instructions on using the CLI, see “Adding HP 3PAR Cluster Extension resource using cluster.exe” (page 22).

1.Add a service or application in the Failover Cluster Management GUI, as described in your Microsoft documentation.

2.Right-click the service or application and select Add a resource > More resources > Add Cluster Extension 3PAR.

NOTE: This step is applicable for creating CLX resources for non CSV disks on Windows Server 2008/2008 R2/2012. Using Failover Cluster Management GUI, we cannot add CLX resource for the CSV disk. See “Configuration of HP 3PAR CLX for CSV disk on Windows Server 2012” (page 37) for configuring CLX resource for CSV disk on Windows Server 2012.

Adding HP 3PAR Cluster Extension resource using cluster.exe

You can use Cluster Command to add a HP 3PAR Cluster Extension resource.

Use the following command to add an HP 3PAR Cluster Extension resource:

cluster resource resource_name /create /group:service_or_application_name /type:"Cluster Extension 3PAR"

NOTE: For Windows Server 2012, Microsoft Failover Cluster Command Interface feature will not be enabled by default when user adds the Microsoft Failover Clustering feature. User need to explicitly select this feature to install on the cluster node.

Example

This command adds an HP 3PAR Cluster Extension resource called clx_fileshare to the CLX_SHARE service or application.

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.
