The cluster ring show command displays a cluster's ring-replication status, which can help you diagnose cluster-wide problems. If your cluster is experiencing problems, support personnel might ask you to run this command to assist with troubleshooting efforts. See “Cluster Replication Rings” for an overview of replication rings.

The following example displays the status of the VLDB replication ring on a node named node0a:

node::> cluster ring show -node node0a -unitname vldb
         Node: node0a
     Unit Name: vldb
        Status: master
         Epoch: 5
   Master Node: node0a
    Local Node: node0a
      DB Epoch: 5
DB Transaction: 56
