ovclusterinfo

NAME

ovclusterinfo

- get information about clusters, cluster nodes, or high-availability (HA) resource groups.

SYNOPSIS

ovclusterinfo  -h | -help 

ovclusterinfo  -v | -version 

ovclusterinfo  -a | -all 

ovclusterinfo  -c | -cluster {-ty | -type} | {-nm | -name} | {-st | -state} | {-nds | -nodes} | {-rgs | -groups} 

ovclusterinfo  -n | -node <node> {-id} | {-st | -state} 

ovclusterinfo  -g | -group <group> {-id} | {-st | -state} | {-ls | -localState} | {-nds | -nodes} | {-vip | -virtualIPAddress} | {-an | -activeNode} 

DESCRIPTION

The ovclusterinfo command gets information about high-availability clusters, cluster nodes, and resource groups. This information includes the name, status, and type of the cluster, as well as the nodes configured in the cluster. The ovclusterinfo command also gets information about high availability (HA) resource groups, including the status, IP address, and nodes contained in the resource group. An HA resource group is a collection of resources (for example, files and processes) that are available on one node in a cluster. They can be switched to another cluster node as a single entity.

Parameters

The ovclusterinfo command accepts the following parameters:

-h | -help

Displays all options for the ovclusterinfo command.

-v | -version

Displays the version of the installed command.

-c | -cluster

Displays information about the named cluster.

-a | -all

Displays all available information about the named cluster, nodes, and resource groups.

-a | -node

Displays all available information about the named node in the cluster.

-g | -group

Displays information about the named HA resource group.

Options

You can use the following options with the appropriate command parameters:

-ty | -type

Display the type of cluster which is installed.

Possible values:

• Microsoft Clustering Services (Windows)
• MC/ServiceGuard (HP-UX)
• VERITAS Cluster Server (Solaris)
• Sun Cluster (Solaris)
• TRU64 Cluster (TCR)
• Red Hat Advanced Server (RHAS)
• HACMP (AIX)
• Unknown

-nm |-name

Name of the cluster.

-st | -state

Status of the cluster on the local node.

This status can be one of the following:

• Cluster is up
• Cluster is down
• State unknown

-nds | -nodes

Displays the names of the nodes in the cluster on separate lines. The cluster configuration determines how the node information displays (for example, short or long host names, IP address, and so on).

-rgs | -groups

All resource groups in the cluster.

-status

Status of the HA resource group, defined by <rgname>, on the local node.

-virtualIPaddress

Virtual IP address of the HA resource group, defined by <rgname>.

-nodes

The list of all nodes to which the HA resource group, defined by <rgname>, can fail over.

-activeNode

Node that currently hosts the HA resource group, defined by <rgname>.

AUTHOR

ovclusterinfo was developed by Hewlett-Packard Company.

EXAMPLES

The following examples show how to use the ovclusterinfo command:

• To display the name of the cluster:

  ovclusterinfo -cluster -name

• To display the names of all HA resource groups in the cluster:

  ovclusterinfo -cluster -groups

• To display the virtual IP address that you configured for the HA resource group haRG:

  ovclusterinfo -group haRG -virtualIPaddress

• To display the name of the node where the HA resource group haRG is currently running.

  ovclusterinfo -group haRG -activeNode
