Pre-executables and post-executables must supply a return code. The return code is used to determine whether a failover function is called.

Pre-execution return codes

Pre-execution return code

Text

Description

0

PRE_OK_TAKEOVER

Pre-executable OK and failover action allowed.

1

PRE_ERROR_GLOBAL

Pre-executable failed; no failover; stop application service

 

 

cluster-wide. Microsoft Cluster service does not allow

 

 

cluster-wide or data-center-wide disabling of resources.

 

 

This is local error behavior.

2

PRE_ERROR_DC

Pre-executable failed; no failover; stop application service

 

 

in this data center. MSFC does not allow cluster-wide or

 

 

data-center-wide disabling of resources. This is local error

 

 

behavior.

3

PRE_ERROR_LOCAL

Pre-executable failed; no failover; stop application service

 

 

on this system.

4

PRE_ERROR_TAKEOVER

Pre-executable failed; failover action allowed.

5

PRE_OK_NOTKVR_NOPST

Pre-executable OK; no failover; no post-exec.

CAUTION: If the pre-execution program returns 1, 2, 3 or 5, a properly configured post-executable is not executed. If a failover function fails, the post-executable is not executed.

Description

0

POST_OK

Post-executable OK; continue.

1

POST_ERROR_GLOBAL

Post-executable failed; stop application service

 

 

cluster-wide. MSFC does not allow cluster-wide or

 

 

data-center-wide disabling of resources. This is local

 

 

error behavior.

2

POST_ERROR_DC

Post-executable failed; stop application service in this

 

 

data center. MSFC does not allow cluster-wide or

 

 

data-center-wide disabling of resources. This is local

 

 

error behavior.

3

POST_ERROR_LOCAL

Post-executable failed; stop application service on this

 

 

system.

4

POST_ERROR_CONTINUE

Post-executable failed; continue without error.

CAUTION: Operating system scripts and/or batch files return 0 if the program was successfully executed. To return a different value, use the following line as the last statement in your pre- or post-executable: Windows batch file: exit /b exitcode.

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.
