3.If you selected RESYNCWAIT in Step 2, set the RESYNCWAIT timeout value.

• Enter the RESYNCWAIT timeout value, in seconds.

4.Select YES or NO as the UseNonCurrentDataOk value in the Replication link down scenario section.

5.Enter the path of the application directory. The application directory is where HP 3PAR Cluster Extension searches for application-specific files, such as the force flag or online file.

6.Click OK to save your changes and close the Advanced settings window.

7.Click Apply to save your changes and leave the window open, or click OK to save your changes and close the Properties window.

Configuring takeover actions

Pre-executables and post-executables can be defined to be executed before or after HP 3PAR Cluster Extension invokes its takeover functions. Use the cluster software Parameters tab or the resource configuration tool to add or remove pre/post executable scripts.

1.Click Pre/Post Exec to display the Pre/Post Executable Properties dialog box.

2.Update the PreExecScript, PostExecScript, and PostExecCheck values as needed, and then click OK.

3.Click Apply to finish your modifications and leave the Properties window open, or click OK to save your changes and close the window.

Setting HP 3PAR Cluster Extension resource properties using the MMC

If you are using Server Core or Hyper-V Server, you can manage a cluster remotely by using the MMC to run Failover Cluster Management.

NOTE: When you configure HP 3PAR 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. You must enter the property values accurately, and verify them against the HP 3PAR Cluster Extension documentation.

When you use this option, you will see the default Microsoft properties page instead of the HP 3PAR Cluster Extension Parameters tab. For more information about using the MMC, see “Remote management of HP 3PAR Cluster Extension resources in a cluster” (page 42) and your Microsoft documentation.

Setting HP 3PAR Cluster Extension resource properties using the CLI

The cluster commands in this section can be used with Windows server core and non server core environments.

The Windows cluster default properties for a resource can be changed using the following command:

cluster resource <resource_name> /privprop [<object_name=value"value1 value2 ...">]

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.
