number of hosts to which the storage devices are connected. For example, if the failover Cluster has [Nh] number of nodes which has CLX software installed and connected to [Na] number of storage devices, user needs to procure only [Na] number of device based permanent licenses – one for each storage device. Using a particular CLX utility, user can import these licenses in all the nodes of the cluster at once. See “Applying Device based permanent license” (page 23) to know how to apply the device based licenses in the CLX setup. User has to choose one of the CLX licensing models in his CLX setup and he needs to decide based on the price set for each node or device based CLX license and the number of host cluster nodes and storage arrays, user has in his CLX setup.

Using the clxautopass command-line utility

In addition to using the clxautopass command to start AutoPass, you can also use the command at the CLI to install the instant-on license and import a password from the license key file.

Installing instanton license keys

If the installation process failed to install the license, you can use the command line to install it. First repair any conditions that may have caused the license installation to fail, and then run the following command to install the license:

clxautopass -installinstanton

Applying host based permanent license

If you have procured host based permanent license, you can use one of the following options to apply the host based permanent license to individual hosts.

Importing a license key from a file

When you receive the license key file by email, import the license key by running the following command:

clxautopass -addpasswords <license file path>

Where license file path is the full (absolute) path name to the license key file.

This command is equivalent to using the Install/Restore License Key from file option in AutoPass.

Using the HP 3PAR Cluster Extension registration tool

To install a license key:

1.For Windows Server 2008/2008 R2: Select Start→All Programs→Hewlett-Packard→HP 3PAR Cluster Extension Software→HP 3PAR Cluster Extension Registration Tool.

For Windows Server 2012: Select Start→All Apps→Hewlett-Packard→HP 3PAR Cluster Extension Registration Tool.

2.Click Browse.

3.Browse to your license key file, and then click Install License.

4.Click Close when you are done installing the license keys.

Applying Device based permanent license

If you have procured device based permanent license, use the following procedures to apply device based permanent license key in clustered and non-clustered environment.

Applying Device based permanent license keys in clustered environment

If you have procured the device based license for HP 3PAR CLX, then you can use this tool to apply license to all the cluster nodes automatically running from one of the cluster nodes. This means

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.
