Verifying Nodes In A Cluster - Cisco MDS 9216 Configuration Manual

Chapter 3 Creating and Managing Clusters

Verifying Nodes in a Cluster

After the cluster is created with the required nodes, you can verify the status of each node in the cluster,
status of each node, and the associated I/O group to ensure the configuration is functioning as desired.
The node state transitions from
To verify the nodes in a cluster, follow these steps.
Verify the nodes in the cluster.
Step 1
switch1(svc)# show cluster SampleCluster nodes
Node node1 is online(3)
Node node2 is online(3)
Node node3 is pending(2)
Node node4 is adding(6)
Verify the I/O group status
Step 2
