"Virtual Machine Configuration" resource is already dependent on the CLX resource, the cmdlet moves to the next VM configuration on a CSV. In the absence of dependency on the existing CLX resource the cmdlet creates a dependency of "Virtual Machine Configuration" resource in the VM role on resource of type "Cluster Extension 3PAR for VM Management".

If there is no resource of type "Cluster Extension 3PAR for VM Management" in the VM role then cmdlet first creates a resource of type "Cluster Extension 3PAR for VM Management" in the VM role and then makes the "Virtual Machine Configuration" resource in the VM role dependent on the newly created resource of type "Cluster Extension 3PAR for VM Management".

A virtual machine configuration resource is brought online after the "Cluster Extension 3PAR for VM Management" type resource that it depends on. Likewise, virtual machine configuration resource is taken offline before the "Cluster Extension 3PAR for VM Management" type resource that it depends on.

PARAMETERS:

-CSVDiskName <String>

Specifies the cluster shared volume name for which all the virtual machine(s) residing on it will be made dependent on resource of type "Cluster Extension 3PAR for VM Management".

Required?

false

Position?

named

Default value

 

Accept pipeline input?

false

Accept wildcard characters?

false

<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug, ErrorAction,

ErrorVariable, WarningAction, WarningVariable, OutBuffer and OutVariable.

For more information, see about_CommonParameters (http://go.microsoft.com/fwlink/? LinkID=113216).

INPUTS:

Does not accept input object.

OUTPUTS:

Does not return object.

NOTES:

The VM roles created using failover cluster Manager GUI are supported.

"Virtual Machine Configuration" resource has to be offline while trying to add the dependency.

If a VM is residing on a CSV which is not dependent on resource of type "Cluster Extension 3PAR", then an error is thrown and no further operations are performed on that VM.

The Confirm parameter and the Force switch parameter are provided.

The cmdlet performs the operations irrespective of the storage array type of CSV.

Online help for the cmdlet is not supported.

Example 1

C:\PS>Add-VMDependencyOnCLX3PAR

This command first finds out all the virtual machine configuration resources which are residing on all the cluster shared volumes. After getting all such virtual machine configurations, it tries to make each virtual machine configuration dependent on resource of type "Cluster Extension 3PAR for VM Management".

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.
