How to Add a Protection Group to a Multigroup

Perform this procedure to add one or more protection groups to a multigroup.

Before You Begin

Ensure that a partner cluster of the protection group you are adding is configured in the site.

1. 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 RBAC rights profile.

   For more information about RBAC, see Chapter 4, Administering RBAC.

   ---

   Note -  If you use a role with Geo Management RBAC 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 RBAC rights profile and data replication software.

2. Add the protection group 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.

   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.

3. Verify the addition of the protection groups.
