Instead of adding a vCenter Server to vMA, it is possible to add just the individual ESXi hosts. This is particularly useful if a single vCenter is used to manage multiple data centers and you don't want to expose all the ESXi hosts managed by the vCenter to the vMA appliance.
The following procedure explains how to add an ESXi server to the vMA appliance:
vifp addserver <ESXi_server_name>
vifp addserver host001.vdescribed.lab
vifp listserverscommand to verify that the ESXi host was added.
