How to Create a Multigroup

Perform this procedure to configure a multigroup to manage designated sets of protection groups.

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, and click Add. 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

  • Ensure that the protection groups you want to contain in the multigroup are configured and working properly. See the Geographic Edition manual for your data replication product for procedures to configure a protection group.

  • Ensure that a partner cluster for each protection group to configure in the multigroup is configured in the same site. See How to Create a Site.

  • If you use a role with Geo Management RBAC 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 ACLs applied for compatibility between the Geo Management RBAC rights profile and data replication software.

    For more information about RBAC, see Securing Geographic Edition Software.

  1. From a node of a site controller cluster, assume the root role or assume a role that is assigned the Geo Management RBAC rights profile.
  2. Create the multigroup.
    site-controller-cluster-node# geomg create -s site multigroup
    -s site

    The name of the site.


    The name to assign the new multigroup. The name must be unique throughout the specified site. If the name is not unique, the command fails with an error.

  3. From a node of a site controller cluster, add protection groups to the multigroup.
    site-controller-cluster-node# geomg add-protection-group protection-group-list multigroup

    The following describes the syntax choices for protection-group-list:


    Specifies a single protection group. The colon (:) separates the cluster name cluster from the name of the protection group that is configured in that cluster.


    Specifies a protection group that has a dependency on another protection group. The protection group that is specified in the dependency chain before the slash (/) depends on the protection group that is specified after the slash.


    The comma (,) separates multiple protection group names in the same command.


    Specifies that the protection groups cluster1:protection-group2 and cluster2:protection-group1 have a dependency on the cluster3:protection-group1 protection group. Use parentheses to only enclose multiple protection groups with a dependency on another, single protection group. Only one protection group can be specified as the depended-on protection group.

  4. Verify the multigroup configuration.
    # geomg status multigroup
