You can display the status of cluster replication rings to help you diagnose cluster-wide problems. If your cluster is experiencing problems, support personnel might ask you to perform this task to assist with troubleshooting efforts.
The following example displays the status of the VLDB replication ring on a node named node0:
cluster1::> set -privilege advanced Warning: These advanced commands are potentially dangerous; use them only when directed to do so by support personnel. Do you wish to continue? (y or n): y cluster1::*> cluster ring show -node node0 -unitname vldb Node: node0 Unit Name: vldb Status: master Epoch: 5 Master Node: node0 Local Node: node0 DB Epoch: 5 DB Transaction: 56 Number Online: 4 RDB UUID: e492d2c1-fc50-11e1-bae3-123478563412
