Creating the DR group

You must create the disaster recovery (DR) group relationships between the clusters.

About this task

You perform this procedure on one of the clusters in the MetroCluster configuration to create the DR relationships between the nodes in both clusters.

Note

The DR relationships cannot be changed after the DR groups are created.

1. Verify that the nodes are ready for creation of the DR group by entering the following command on each: metrocluster configuration-settings show-status

   Example

   The command output should show that the nodes are ready:

   cluster_A::> metrocluster configuration-settings show-status
   Cluster                    Node          Configuration Settings Status
   -------------------------- ------------- --------------------------------
   cluster_A                  node_A_1      ready for DR group create
                              node_A_2      ready for DR group create
   2 entries were displayed.
   

   cluster_B::> metrocluster configuration-settings show-status
   Cluster                    Node          Configuration Settings Status
   -------------------------- ------------- --------------------------------
   cluster_B                  node_B_1      ready for DR group create
                              node_B_2      ready for DR group create
   2 entries were displayed.
   
2. Create the DR group: metrocluster configuration-settings dr-group create -partner-cluster partner-cluster-name -local-node local-node-name -remote-node remote-node-name

   This command is issued only once. It does not need to be repeated on the partner cluster. In the command, you specify the name of the remote cluster and the name of one local node and one node on the partner cluster.

   The two nodes you specify are configured as DR partners and the other two nodes (which are not specified in the command) are configured as the second DR pair in the DR group. These relationships cannot be changed after you enter this command.

   The following command creates these DR pairs:

   • node_A_1 and node_B_1

   • node_A_2 and node_B_2

   Cluster_A::> metrocluster configuration-settings dr-group create -partner-cluster cluster_B 
   -local-node node_A_1 -remote-node node_B_1
   [Job 27] Job succeeded: DR Group Create is successful.
