Return codes

clx3PARrun expects only the app_name parameter, which uniquely identifies an application service in the APPLICATION section of the user configuration file.

To force a Remote Copy volume group failover, use the

–forceflag option.

CAUTION: The forceflag option is an emergency switch used to manually activate your virtual volume. If the forceflag option has been specified, HP 3PAR Cluster Extension will not check any consistency or concurrency rules before activating the virtual volume in the associated volume group.

clx3PARrun exits with one of the following return codes:

0 OK Application service can be started.

1ERROR_GLOBAL Application service could not start on any node in either site on either HP 3PAR storage system.

2ERROR_DC Application service could not start on any node in the local site on the local HP 3PAR storage system.

3 ERROR_LOCAL Application service could not start on this node.

13ERROR_REPLICATION_IO_NOT_STARTED Application service can be started but Remote Copy replication is not started for the Remote Copy volume group.

14ERROR_REPLICATION_IO_STARTING Application service can be started but Remote Copy replication is being started for the Remote Copy volume group.

Configuring the CLI

The following configuration steps are required before using the HP 3PAR Cluster Extension CLI:

1.“Creating the HP 3PAR Remote Copy environment” (page 56)

2.“Configuring the HP 3PAR storage system” (page 56)

3.“Installing HP 3PAR InForm Command Line Interface (CLI)” (page 57)

4.“Creating and configuring the user configuration file” (page 57)

Creating the HP 3PAR Remote Copy environment

HP support personnel are trained to set up HP 3PAR Remote Copy environments. You can create and configure Remote Copy volume groups by either using the HP 3PAR InForm Management Console GUI or CLI. For more information, see HP 3PAR Remote Copy User Guide.

Configuring the HP 3PAR storage system

To configure the HP 3PAR storage system you must:

Create hosts

Create virtual volumes and add a LUN presentation

Create Remote Copy volume groups

Add a LUN presentation to the secondary virtual volumes

For detailed procedures, see the HP 3PAR InForm Management Console User Guide or the HP 3PAR InForm CLI Administrator’s Manual.

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.
