Page 53

Do not specify arguments to be passed to the executable.

ResyncWaitTimeout (Optional)

Format

Integer

Description

Specifies the value (in seconds) for checking the status of the Remote Copy volume

 

group resynchronization. It might take some time to resynchronize member virtual

 

volumes. You can set this value if the ApplicationStartup property is set to

 

RESYNCWAIT.

Default

90

value

 

StatusRefreshInterval

Format

Integer

Description

Specifies how often HP 3PAR Cluster Extension will gather HP 3PAR storage array

 

volume group information.

Default

300 seconds

value

 

UseNonCurrentDataOk (Optional)

Format

String

Description

When the replication link is down, this property specifies whether HP 3PAR Cluster

 

Extension can fail over to the destination site when the data at the destination site

 

might not be current.

 

If a HP 3PAR Remote Copy link goes down, and the resource is moved to the remote

 

data center:

 

• Setting this value to YES means that, regardless of whether or not the data is

 

current in the remote data center, the resource will come online.

 

• Setting this value to NO means that the resource will not come online on the

 

remote data center since data might not be current.

Valid values

YES (default)

 

NO

HP3PARCLICommandTimeout

Format

Integer

Description

Specifies timeout value (in seconds) for HP 3PAR storage system command execution.

 

The timeout value is used whenever HP 3PAR Cluster Extension communicates with

 

the HP 3PAR storage system. If the storage system is not responding within the

 

configured timeout value, the command will time out and returns an error to the

 

application.

Default

90 seconds

value

 

Sample configuration file

The following is a sample UCF.cfg file:

COMMON

#LogLevel info # errorinfo default: error (optional) #HP3PARCLICommandTimeout 60 #HP3PARRCPeriodicLinkDownTimeout 250

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.
