Put ESX in Maintenance mode

Put ESX in Maintenance mode

I will have to shutdown an ESX servers, so that I can open it up and put a new DIMM.
the ESX server hosts about 20 VMs.
If I understand, I will just have to right-click on the ESX server in Vcenter then click "Enter Maintenance Mode" and wait for the VMs to show up under another ESX server. Then when all VMs are no longer showing up under the ESX tha was put in maintenance mode, I can go ahead and shut it down and replace the DIMM.

Well, that's the first part. The second will be just to power it back on, then right-click on it on the Vcenter and click on "Exit Maintenance mode" I believe that's what would show up as taking the ESX out of maintenance mode.
I believe  ESX servers in the cluster would balance themselves, without me moving manually the VMs.

If I am missing any steps, please advise.

Thank you

If you have HA and VMotion enabled when put into maintenance mode they should move off.  I am assuming you have a SAN and the allotted space and hardware needed for the VMs to move and sit comfortably?

yes VMs are in the SAN.

I believe physically they stay where they are, they do not move.
The only thing that will change it is that another ESX will be providing them CPU and Memory resources.

DRS is enabled , HA (I guess it is not important in this scenario since the ESX will be put in maintenance mode before shut down)

If you put a server into Maintenance Mode, VMs will ONLY MOVE, if the DRS is set to Fully Automatic.

After Maintenance, when you have brought the server back up, EXIT Maintenance Mode, and if DRS is Fully Automatic, you will find the VMs will be re-distributed!

The moment you Right Click Enter Maintence Mode, they should start to move...

just remember to disconnect all floppy disk and cdroms, and iso images.
