HP Cluster Software manual Setting HP 3PAR Cluster Extension properties using a UCF

Page 34

NOTE: When you configure HP 3PAR Cluster Extension resource properties using the CLI, 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.

You can display all attributes of the HP 3PAR Cluster Extension resource clx_fileshare with the following command:

cluster resource clx_fileshare /privprop

The following example sets the UseNonCurrentDataOk property for the resource clx_fileshare to NO:

cluster resource clx_fileshare /privprop UseNonCurrentDataOk=NO

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

The following example changes the name of the resource 3PAR Cluster Extension resource1 to 3PAR Cluster Extension resource2:

cluster resource "3PAR Cluster Extension resource1" /ren:"3PAR Cluster Extension resource2"

Setting HP 3PAR Cluster Extension resource properties using the Microsoft Failover PowerShell Cmdlets

The cluster commands in this section can be used with Windows Server 2008/2008 R2/2012, Server Core, or Hyper-V Server. The Windows cluster default properties for a resource can be changed using the command: Get-ClusterResource "resource_name"

Set-ClusterParameter -Name "property_name" -Value "value_to_set"

NOTE: When you configure HP 3PAR Cluster Extension resource properties using the PowerShell, 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.

The following example sets the UseNonCurrentDataOk property for the resource clx_fileshare to NO

Get-ClusterResource "clx_fileshare" Set-ClusterParameter -Name "UseNonCurrentDataOk" -Value NO

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

Setting HP 3PAR Cluster Extension properties using a UCF

You can use a UCF to configure certain HP 3PAR Cluster Extension properties. Properties that you can configure in a UCF include:

•LogLevel

•ClusterNotifyCheckTime

•ClusterNotifyWaitTime

•StatusRefreshTime

•HP3PARCLICommandTimeout

IMPORTANT: If you plan to use the default values for these properties, no UCF is required.

To configure properties using a UCF:

1.Take the HP 3PAR Cluster Extension resource offline.

2.Open the sample UCF.cfg file located in %ProgramFiles%\Hewlett-Packard\Cluster Extension 3PAR\sample.

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.
