4 CLI commands and utilities

Using its CLI and command-line utilities, HP 3PAR Cluster Extension can be integrated with almost any cluster software.

CLI commands

The HP 3PAR Cluster Extension CLI command clx3PARrun can be:

•Used as a standalone utility

•Integrated into any cluster software or custom application

clx3PARrun

Description

Use clx3PARrun to manually prepare the application service's

 

disk set before an existing application service start procedure is

 

invoked. You can use clx3PARrun in custom solutions and startup

 

scripts.

 

 

When using clx3PARrun, the status of the associated volume

 

group is checked to ensure that access to the virtual volume(s) will

 

occur under data consistency and concurrency situations only.

 

You must invoke clx3PARrun before the application service disk

 

set can be activated; it is considered an online-only program.

 

However, the CLI features provide the same disaster recovery

 

features as the integrated versions of HP 3PAR Cluster Extension.

Syntax

clx3PARrun [–version][–forceflag]app_name

Operands

–version

Displays the HP 3PAR Cluster Extension version

 

–forceflag

Force startup

 

app_name Application name configured in the UCF.cfg file

Example 1

This example assumes you have defined an APPLICATION tag

 

named my-exchangein the UCF.cfg file, and have specified all

 

necessary objects, including the RCVolumeGroupA and

 

RCVolumeGroupB objects, to map the Remote Copy volume group

 

to the application service my-exchange. HP 3PAR Cluster Extension

 

will check the virtual volume set mapped to the application service

 

my-exchange, run the necessary failover procedure, and generate

 

a return code.

 

 

# clx3PARrun my-exchange

Example 2

This example assumes you have defined an APPLICATION tag

 

named my-exchangein the UCF.cfg file and have specified all

 

necessary objects, including the RCVolumeGroupA and

RCVolumeGroupB objects, to map the Remote Copy volume group to the application service my-exchange. HP 3PAR Cluster Extension will check the virtual volume set mapped to the application service my-exchange, and run the necessary failover procedure to enable read/write access to the virtual volumes.

# clx3PARrun -forceflag my-exchange

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.
