How to Remove a Cluster From a Site

Perform this procedure to make a cluster remove itself from a site. If the cluster you want to remove from a site is unreachable, instead follow How to Remove an Unreachable Cluster From a Site a Cluster.

Note -  To remove the last cluster from a site, instead follow How to Delete a Site.

Note -  You can also use the Oracle Solaris Cluster Manager browser interface to perform this task.
  • To remove the local cluster, click Sites, highlight the site name, and click Leave Site.

  • To remove another cluster, click Sites, click the site name to go to its page, highlight the cluster name, and click Remove,

For Oracle Solaris Cluster Manager log-in instructions, see How to Access Oracle Solaris Cluster Manager in Administering an Oracle Solaris Cluster 4.4 Configuration.

  1. From a node of the cluster that you want to remove from a site, assume the root role or assume a role that is assigned the Geo Management rights profile.

    For more information, see Disaster Recovery Framework Rights Profiles in Installing and Configuring the Disaster Recovery Framework for Oracle Solaris Cluster 4.4.

    Note -  If you use a role with Geo Management rights, ensure that the /var/cluster/geo ACLs are correct on each node of both partner clusters. If necessary, assume the root role on the cluster node and set the correct ACLs.
    # chmod A+user:username:rwx:allow /var/cluster/geo

    The /var/cluster/geo directory must have the correct access control lists (ACL) applied for compatibility between the Geo Management rights profile and data replication software.

  2. Detach the issuing cluster from the site.
    • If the cluster is not the last controller in the site, use the following command.
      node-of-cluster-to-remove# geosite leave site

      The name of the site to remove the cluster from.

    • If the cluster is the last controller in the site, include the –f option in the command.
      node-of-cluster-to-remove# geosite leave -f site
      • If the site contains other member clusters, the site continues to exist without a site controller.

      • If the site has no other member clusters, removal of the last controller also deletes the site.

        Note -  If the last site member being removed is not a site controller, the remove command fails with an error.
  3. From a remaining site cluster, verify that the removed cluster is no longer listed as a site member.
    # geosite show -v site
             *** Site "site" is not configured ***
