Sun Cluster Geographic Edition System Administration Guide

ProcedureHow to Create a Heartbeat

Use this procedure to create a new heartbeat. To use the heartbeat with a partnership, you must create the heartbeat before you create a partnership. If you create a partnership before you create the custom heartbeat, the default heartbeat that is used by the partnership will prevent the custom heartbeat from being created.

If you create a custom heartbeat, you must add at least one plug-in to prevent the partnership from remaining in degraded mode.

A custom heartbeat prevents the default heartbeat from being used during partnership creation. If you want to use the default heartbeat for your partnership, you must delete the custom heartbeat before running the geops create command.

  1. Log in to a cluster node.

    You must be assigned the Geo Management RBAC rights profile to complete this procedure. For more information about RBAC, see Sun Cluster Geographic Edition Software and RBAC.

  2. Create the heartbeat.


    # geohb create -r remoteclustername \
    [-p propertysetting [-p...]] heartbeatname
    
    -r remoteclustername

    Specifies the name of the remote, secondary partner cluster.

    -p propertysetting

    Specifies a heartbeat property that is assigned a value by using a name=statement pair. Multiple properties might be set at one time by using multiple statements.

    For more information about the properties you can set, see Appendix A, Standard Sun Cluster Geographic Edition Properties.

    heartbeatname

    Specifies an identifier for the heartbeat.

    If you create a custom heartbeat, you must add at least one plug-in to prevent the partnership from remaining in degraded mode.


    Caution – Caution –

    The name of the custom heartbeat on each cluster in the same partnership must be different. Choose a name that identifies the heartbeat uniquely, such as paris-to-newyork on the cluster cluster-paris and newyork-to-paris on cluster cluster-newyork.


    For more information about the geohb command, refer to the geohb(1M) man page.


Example 6–1 Creating a Heartbeat

This example creates a heartbeat that is named paris-to-newyork.


# geohb create -r cluster-newyork paris-to-newyork
