Error return codes

Description

 

Copy replication using HP 3PAR Management GUI or CLI

 

when required.

Replication I/O starting error

Replication I/O between the primary and secondary

 

Remote Copy volume group is started. Use HP 3PAR

 

Management GUI or CLI to check if the replication status

 

is started or not. You can manually start the Remote

 

Copy replication using HP 3PAR Management GUI or CLI

 

when required.

When HP 3PAR Cluster Extension is integrated into the cluster software, an error message string and integer value are displayed. For the CLI, a return code is displayed. For more information, see “CLI commands” (page 55).

Log files

Log files assist you in locating and identifying problems. Timestamps, component IDs, and message IDs are included.

HP 3PAR Cluster Extension-related messages are logged by MSFC to the file cluster.log in the location %windir%\Cluster\Reports.

For each system, HP 3PAR Cluster Extension keeps its own log file in its default log location.

Log file

Log location

clxmscs.log

%HPCLX_3PAR_PATH%\log

VMClxMscs.log (For VM Management on

%HPCLX_3PAR_PATH%\log

Windows Server 2012 only)

 

CLXCmdlet.log

%HPCLX_3PAR_PATH%\log

HP 3PAR Cluster Extension messages can also be found in the following:

MSFC log file [%windir\cluster\reports\cluster.log]

Always disable automatic service or application failover when merging or resynchronizing Remote Copy volume groups. A failure of the resynchronization source while resynchronizing can lead to noncurrent data on the resynchronization target.

Start errors

Generic startup or initialization logic errors can occur when the path to the HP 3PAR Cluster Extension binaries has not been set in the PATH environment variable and the processes (for example the cluster service) have not recognized the %HPCLX_3PAR_PATH% variable. To fix this problem, restart the cluster service.

If the required components of HP 3PAR Cluster Extension are not available, a file (clxlog.log ) is generated that can be used for troubleshooting. The file is usually in the working directory of the operating system (%SYSTEMROOT%).

HP 3PAR Cluster Extension returns a local error if any of the following occurs:

HP 3PAR Cluster Extension does not find the user configuration file for clx3PARrun in the correct directory location.

An error occurs after initialization.

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.
