Start Cluster

1. Using the vSphere client, take the ESXi hosts out of maintenance mode
2. Power on the CVM’s within the cluster
3. SSH into one of the CVM’s, and issue the following command:
   

   cluster start

4. Once completed, it will report back showing that all services are running on all the CVM’s within the cluster
5. Validate that the datastores are available and connected to all hosts within the cluster
6. Power on guest VM’s

Stop Cluster

1. Power down all VM’s running in the cluster, with the exception of the CVM’s
2. SSH into one of the CVM’s, and issue the following command:
   

   cluster stop

3. Once completed, it will report back showing that all services have stopped with the exception of a couple
4. Perform a guest shutdown of the CVM’s
5. Place the ESXi hosts into maintenance mode
6. Power down the ESXi hosts

Check Cluster Status

1. SSH into one of the CVM’s, and issue the following command:
   

   cluster status

2. Once completed, it will report back the status of the cluster

Expand Cluster

Configuration	Description
Same hypervisor and AOS version	The node is added to the cluster without re-imaging it.
AOS version is different	The node is re-imaged before it is added.
AOS version is same but hypervisor version is different	You are provided with the option to re-image the node before adding it. (Re-imaging is appropriate in many such cases, but in some cases it may not be necessary such as for a minor version difference.)
Data-At-Rest Encryption	You are provided with the option to re-image the node before adding it. (Re-imaging is appropriate in many such cases, but in some cases it may not be necessary such as for a minor version difference.)

• You can add multiple nodes to an existing cluster at the same time
