3.Update the file with the property values you want to use.

For more information on the available properties, see “User configuration file and HP 3PAR Cluster Extension objects” (page 47).

4.Save the file and copy it to the following directory on all cluster nodes: %ProgramFiles%\ Hewlett-Packard\Cluster Extension 3PAR\conf.

5.Bring the HP 3PAR Cluster Extension resource online.

Adding dependencies on a HP 3PAR Cluster Extension resource

HP 3PAR Cluster Extension Software must be the first resource in the resource chain of a Windows cluster service or application. All resources that depend on the disk resource, such as a file share, and all disk resources (physical disks), must be configured for dependency on the HP 3PAR Cluster Extension resource.

To add dependencies:

•Use the Failover Cluster Management GUI, cluster commands in the CLI, or the MMC for remote management.

•For Server Core or Hyper-V Server, use cluster commands in the CLI or the MMC.

Adding dependencies using Failover Cluster Management

You can add dependencies with the GUI on a local node or by using the MMC to run the Failover Cluster Management application.

1.Open Failover Cluster Management.

2.Select a service or application that has HP 3PAR Cluster Extension resource.

3.Double-click a disk in the summary pane.

4.Click the Dependencies tab, and then click Insert.

5.Select the HP 3PAR Cluster Extension resource in the Resource menu.

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.
