A Virtual Execution appliance serves no purpose until it is added to a cluster. After you add a Virtual Execution appliance to the Central Management appliance, it is an available node that can be added to an IVX cluster. You can determine whether a Virtual Execution appliance is an available node from the Central Management Web UI or CLI and the Virtual Execution CLI.
The Cluster column in the Central Management Web UI indicates whether a node is available.
The Node information section in the following CLI command output is empty because the vx-2 node is not currently part of a cluster, so it is available.
vx-2 # show mvx node status full MVX Cluster: Node Status
