VCenter as a VM Need to shutdown all vSphere hosts

vmware-vcenter

Due to a physical move I am going to have to shut down all of my vSphere hosts running 4.0 u1 My concern is that I run vCenter as a VM. My plan is to shut down all VM's via VC prior to shuting down the hosts. then shutdown VC server via the console and then power off the hosts. A couple questions though Should I put the esx hosts in maintenance mode prior to shutting down VC? since I use DRS and shared storage I am aware the VC host can and does move but will I be able to power on the hosts and browse them via the vSphere client in order to restart VC first? (there are only 7 hosts so not a huge deal to go loooking. )

Am I missing anything?

Thanks.

You should be fine.

To power everything off.

  1. Shut down all VM's (apart from the vCenter Server and its SQL server if it's a separate VM).
  2. Then put all all the hosts apart from the one running vCenter\SQL into maintenance mode and shut them down.
  3. Shut down the VC box and the SQL box (if needed) from an RDP session or using a VI Client session connected to the remaining host.
  4. Now shut down the last host. Remember which one this was as you want to restart this one first since the VC server is registered to this host and restarting it is straightforward.

To start up again.

  1. Power up the last host you shut down and connect to it with the VI Client.
  2. Start up SQL (again only if it's a separate VM) and then start up the vCenter VM.
  3. Disconnect the VI Client from the single host and connect to vCenter.
  4. Now start up your hosts and take them out of maintenance mode.
  5. You can begin starting VM's as soon as you have a couple of Hosts running and out of Maintenance mode, just make sure you don't try to start so many that you overload the available host resources before the cluster is back to sufficient strength.
