How to Create a Multigroup

Language:

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 Administering an Oracle Solaris Cluster 4.4 Configuration.

Before You Begin

Ensure that the protection groups you want to contain in the multigroup are configured and working properly. See the Oracle Solaris Cluster guide 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.

From a node of a site controller cluster, 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.
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.
Create the multigroup.
```
site-controller-cluster-node# geomg create -s site multigroup
```
-s site

The name of the site.

multigroup

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.
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:

cluster:protection-group

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.

cluster1:protection-group1/cluster2:protection-group2

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.

cluster1:protection-group1,cluster1:protection-group2,cluster2:protection-group1/cluster3:protection-group1

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

(cluster1:protection-group2,cluster2:protection-group1)/cluster3:protection-group1

Specifies that multiple protection groups, cluster1:protection-group2 and cluster2:protection-group1, all have a dependency on the cluster3:protection-group1 protection group. Parentheses can only be used to 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.
Verify the multigroup configuration.
```
# geomg status multigroup
```

To administer a multigroup, see Chapter 9, Administering Multigroups in Administering the Disaster Recovery Framework for Oracle Solaris Cluster 4.4.
