batch script to start VMs

since my vCenter is a VM inside one of ESXis, i would like to create a batch to achieve below in sequence:

1) check if AD VM on ESXi A or ESXi B then power on AD VM on that ESXi, repeat with listed VMs:

-vCenter

-View Security Server

2) remount NFS datastores that cannot be browsed its contents

3) restart vCenter Update Manager service

thanks in advance
