The generated password file is stored in the directory from where the command shell is launched.

For example, if you use %HP 3PAR CLI PATH% to login to the command shell, the generated password file location will be <HP 3PAR CLI PATH>\bin.

IMPORTANT: If there is any change in the configured IP address of the array or password file location and content, Cluster Extension will fail to communicate with the array and will not perform the required actions. At any point of time, you can launch the HP 3PAR Configuration tool and use the Connection Test option to verify connectivity and array credentials, and take necessary action.

Administration

Cluster Extension administration includes remote management of resources and monitoring of system resources and logs.

Remote management of HP 3PAR Cluster Extension resources in a cluster

You can use the MMC with Failover Cluster Management to manage clusters and configure HP 3PAR Cluster Extension resources. Note the following when configuring HP 3PAR Cluster Extension resources by using the MMC from a remote management station:

•When you use the MMC to remotely configure HP 3PAR Cluster Extension resource properties in a Server Core or Hyper-V Server cluster node, the Failover Cluster Management GUI on the remote management station displays the standard Microsoft Properties tab instead of the customized HP 3PAR Cluster Extension Parameters tab. For more information about the Parameters tab, see “Setting HP 3PAR Cluster Extension resource properties using the MMC ” (page 33).

•When you install HP 3PAR Cluster Extension into a Windows Server 2008/2008 R2/2012 environment, the resource extension DLL is registered by default, which prevents you from configuring a HP 3PAR Cluster Extension resource from a remote management station. If you need to remotely configure a HP 3PAR Cluster Extension resource in a Windows Server 2008/2008 R2/2012 based cluster, unregister clx3PARmscsEx.dll from the cluster node, which allows you to configure the HP 3PAR Cluster Extension resource using the standard Microsoft Properties tab. Use the command cluster /UNREGADMINEXT:Clx3PARmscsEx.dll to unregister the DLL.

CAUTION: Configuring HP 3PAR Cluster Extension resources using the MMC from a remote management station is supported using only the standard Microsoft Properties tab. Do not try to use the customized HP 3PAR Cluster Extension Parameters tab for this purpose.

•If you see the customized HP 3PAR Cluster Extension Parameters tab when you try to configure HP 3PAR Cluster Extension resource from a remote management station using the MMC, you must unregister clx3PARmscsEx.dll from the cluster node. Use the command cluster/ UNREGADMINEXT:clx3PARmscsEx.dll to unregister the DLL. Unregistering the DLL allows you to configure the resource using the standard Microsoft Properties tab. This situation might occur if you have a cluster with both Server Core or Hyper-V Server and Windows Server 2008/2008 R2/2012 cluster nodes.

•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, so you must enter the property values accurately, and verify them against the HP 3PAR Cluster Extension documentation.

•On Windows Server 2012 Failover Cluster, user cannot use the MMC to remotely configure the CLX resource on which CSV disk is dependent. Hence in Windows 2012 Server Core machine, user has to launch HP 3PAR Resource Configuration Tool (Clx3PARResConfig.exe) to configure the CLX resource for the CSV disk. In non-servercore Windows Server 2012,

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.
