vcmp chassis upgarde

Hello.

So First of don't forget to backup all your Guests and your Host. Then before rebooting your host on the new Volume you have to shutdown all your Guest (set your Guest to Configured):

Before restarting or upgrading a host system, you should perform a graceful shutdown of all guest systems running on the host. To do so, perform the following procedure:

Log in to the host system's Configuration utility.
Navigate to vCMP > Guest List.
Click the name of the guest system you want to shut down.
From the Requested State menu, select Configured.
Click Update.
