How to Take Over a Multigroup

Language:

Perform this procedure to transfer all operation of protection groups in a multigroup to partner clusters in the specified site.

Note - To take over a protection groups that is not configured as a multigroup, instead follow procedures in How to Force Immediate Takeover of a Protection Group by a Secondary Cluster.

Caution - To avoid possible loss of replicated data, use instead the geomg switchover command. The geomg takeover command is intended only for situations where the potential risk of data loss is justified, such as when the primary site is not available or during unplanned downtime.

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 ACL applied for compatibility between the Geo Management rights profile and the 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 of the target site, assume the root role or assume a role that is assigned the Geo Management rights profile.
Initiate takeover of the multigroup by the standby site.
```
# geomg takeover [-f] -s site multigroup
```
-f

Forces takeover, even if the primary cluster for a protection group in the multigroup is reachable and the protection group is active on that cluster.

-s site

The name of the standby site which is to take over the specified multigroup.

multigroup

The name of the multigroup to take over.

See the geomg(1M) man page for information about additional options for the takeover subcommand.
