Renaming a cluster in MetroCluster configurations

Renaming a cluster in a MetroCluster configuration involves making the changes, and then verifying on both the local and remote clusters that the change took effect correctly.

1. View the cluster names using the metrocluster node show command:

   Example

   cluster_1::*> metrocluster node show
   DR                               Configuration  DR
   Group Cluster Node               State          Mirroring Mode
   ----- ------- ------------------ -------------- --------- --------------------
   1     cluster_1
                 node_A_1           configured     enabled   normal
                 node_A_2           configured     enabled   normal
         cluster_2
                 node_B_1           configured     enabled   normal
                 node_B_2           configured     enabled   normal
   4 entries were displayed.
   
   
2. Rename the cluster: cluster identity modify -name new_name

   Example

   In the following example, the cluster_1 cluster is renamed cluster_A:

   cluster_1::*> cluster identity modify -name cluster_A
   
3. Verify on the local cluster that the renamed cluster is running normally: metrocluster node show

   Example

   In the following example, the newly renamed cluster_A is running normally:

   cluster_A::*> metrocluster node show
   DR                               Configuration  DR
   Group Cluster Node               State          Mirroring Mode
   ----- ------- ------------------ -------------- --------- --------------------
   1     cluster_A
                 node_A_1           configured     enabled   normal
                 node_A_2           configured     enabled   normal
         cluster_2
                 node_B_1           configured     enabled   normal
                 node_B_2           configured     enabled   normal
   4 entries were displayed.
   
   
4. Rename the remote cluster: cluster peer modify-local-name -name cluster_2 -new-name cluster_B

   Example

   In the following example, cluster_2 is renamed cluster_B:

   cluster_2::> cluster peer modify-local-name -name cluster_2 -new-name
   cluster_B
   
   
5. Verify on the remote cluster that the local cluster was renamed and is running normally: metrocluster node show

   Example

   In the following example, the newly renamed cluster_B is running normally:

   cluster_B::*> metrocluster node show
   DR                               Configuration  DR
   Group Cluster Node               State          Mirroring Mode
   ----- ------- ------------------ -------------- --------- --------------------
   1     cluster_B
                 node_B_1           configured     enabled   normal
                 node_B_2           configured     enabled   normal
         cluster_A
                 node_A_1           configured     enabled   normal
                 node_A_2           configured     enabled   normal
   4 entries were displayed.
   
   
6. Repeat these steps for each cluster that you want to rename.
