How to Add a Protection Group to a Multigroup

Language:

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, click the multigroup name to go to its page, and click Add Protection Group. 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 a partner cluster of the protection group you are adding is configured in the site.
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.

From a node of a controller cluster for the site to configure with the new multigroup, assume the root role or assume a role that is assigned the Geo Management rights profile.
Add the protection group to the multigroup.
```
site-controller-cluster-node# geomg add-protection-group protection-group-list multigroup
```
The syntax choices for protection-group-list are as follows:

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.

cluster:protection-group/cluster:protection-group

Specifies a protection group that has a dependency on another protection group, called a dependency chain: The protection group that is specified before the slash (/) in the dependency chain 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 protection-group list.

(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. In this form of dependency chain, parentheses are only used to enclose the multiple protection groups that have a dependency on another, single protection group. Only one protection group can be specified as the depended-on protection group in the dependency chain.

For more information, see the geomg(1M) man page.

Verify the addition of the protection groups.
