How to Remove an Unreachable Cluster From a Site

Perform this procedure to remove from a site a cluster that is unreachable. If a cluster you want to remove is reachable, instead follow How to Remove a Cluster From a Site.

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. 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 Oracle Solaris Cluster 4.3 System Administration Guide.

Before You Begin

If you use a role with Geo Management rights, ensure that the /var/cluster/geo access control lists (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 ACL applied for compatibility between the Geo Management rights profile and data replication software.

For more information, see Securing Geographic Edition Software in Oracle Solaris Cluster 4.3 Geographic Edition Installation and Configuration Guide.

  1. From a node of a site controller cluster, assume the root role or assume a role that is assigned the Geo Management rights profile.
  2. Remove the cluster from the site.
    site-controller-cluster-node# geosite remove-member cluster site

  3. From a remaining site cluster, verify that the removed cluster is no longer listed as a site member.
