HP Cluster Software Managing HP 3PAR Cluster Extension resources, Bringing a resource online

Page 39

1.Log in to the host3_DCB system with the Administrator account.

2.Create the file share service or application with all previously mentioned resources and its dependencies, except the HP 3PAR Cluster Extension resource on host3_DCB.

3.Create a new resource of type HP 3PAR Cluster Extension and add systems host2_DCA, host3_DCB and host4_DCB to its possible owners.

4.Change the restart behavior of the resource so that the resource can be restarted and that the restart affects the service or application. Set the number of restarts to 0.

5.Edit the properties in the Parameters tab to configure your resource. Configure Remote Copy volume group and the respective HP 3PAR storage mapping for DCA and DCB (DC_A_Hosts, and DC_B_Hosts.

6.(Optional step) Click the Pre/Post Exec button and add clxpre.exe with its full path. (The clxpre.exe program is an example. It is not included with this product.

7.Add a dependency on the resource CLX_FILESHARE to the physical disk resource

Disk_3PAR_LUN25.

8.Check the cluster service group and resource settings using the following commands:

C:\>cluster group CLX_SHARE /prop C:\>cluster resource CLX_FILESHARE /prop

9.Set the CLX resource property as below:

C:\cluster resource CLX_FILESHARE /ProP RestartAction=0

C: \cluster resource CLX_FILESHARE /ProP

Set the CLX resource property as below:

a.Click the Policies tab of the Failover Cluster Management Properties window.

b.For the HP 3PAR Cluster Extension resource property response to resource failure, select If resource fails, do not restart.

10.Bring the service or application online on host3_DCB, and verify that the resource and all other CLX_SHARE service or application resources are brought online.

11.Take the service or application offline, and verify that all resources are stopped.

12.Bring the service or application online again, and verify that all resources are available.

13.Check the cluster service settings of nodes host4_DCB, the service or application and resource settings.

14.Move the service or application to node host4_DCB and verify that all resources are available.

15.Check the cluster service settings of systems host2_DCA, the service or application and resource settings.

16.Move the service or application to node host2_DCA and verify that all resources are available.

17.Check the cluster service settings of node host1_DCA, the service or application and resource settings.

18.Take the service or application offline and verify that all resources are stopped.

19.Change the resource to be able to restart on another system.

Managing HP 3PAR Cluster Extension resources

You can manage resources by bringing them online and offline, or by deleting them.

Bringing a resource online

Resources are usually brought online automatically when the service or application is brought online. You might need to move the service or application to the node where you want to bring the resource online.

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.
