How to Add a Cluster to a Site

Language:

Perform this command to add one or more clusters to an existing site. You can add a global cluster or a zone cluster. For procedures to create a site, see How to Create a Site in Installing and Configuring the Disaster Recovery Framework for Oracle Solaris Cluster 4.4.

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 in the Clusters section 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.

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 in Installing and Configuring the Disaster Recovery Framework for Oracle Solaris Cluster 4.4.
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.

Ensure that all nodes of the site controller cluster are online.

phys-schost-1# cluster status -t node
=== Cluster Nodes ===

--- Node Status ---

Node Name                                       Status
---------                                       ------
phys-schost-2                                   Online
phys-schost-1                                   Online

If any node is offline, wait until the node is brought back up before you issue the site invitation. The addition of a new cluster to a site will fail if any node in the issuing cluster is not online.

Invite the cluster to join the site.
- To add the cluster as a site controller, use the following command.
```
site-controller# geosite add-member -c cluster site
```
- To add the cluster as a member, use the following command.
```
site-controller# geosite add-member -m cluster site
```
  –c
  
  Specifies the site controller role.
  
  –m
  
  Specifies the site member role.
  
  cluster
  
  The name of the cluster to add to the site. To add multiple clusters, separate the cluster names with a comma (,). You can use both the –c and –m options in the same geosite add-member command.
  
  site
  
  The name of the site that you are adding the cluster to.

Verify the invitation.

Command output is similar to the following, where the new cluster is added as a site controller.

site-controller## geosite status

   Site : site

    Controller "issuing-cluster"
    Configuration               : OK

    Controller "added-cluster"
    Configuration               : OK
    Synchronization             : Unknown
…

Troubleshooting

If the geosite add-member command fails with a timeout, update the site's Timeout value to a larger number and retry the command.

Next Steps

To complete the addition of the cluster to the site, the invited cluster must join the site. Go to How to Accept an Invitation to Join a Site.
