Synchronizing Multigroup Configuration Information

Under normal circumstances, information about a multigroup configuration change is automatically synchronized among all clusters in the multigroup.

This section describes how to manually update the locally known configuration information of a multigroup with the configuration information known to another cluster in the site. Synchronization of a multigroup is normally performed automatically after you add or remove a protection group. You would perform this procedure if synchronization failed for one or more clusters of the multigroup site. The configuration information known to the local cluster is overwritten by information from the specified remote cluster in the site.

How to Synchronize Multigroup Configuration Information

Perform this procedure to manually synchronize multigroup configuration information within 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 multigroup name, and click Validate. 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 controller cluster of the local site, assume the root role or assume a role that is assigned the Geo Management rights profile.
  2. Synchronize the multigroup configuration information with the remote cluster in the site.
    # geomg update remote-site-cluster multigroup-name

    For more information about multigroup synchronization states, see the geoadm(1M) man page.
