Cannot get the cpu mask ID

Hello,

I have a problem with finding the right cpu mask, i hope that someone can help me out on this one.

Underneath is the error that i get:

7126_7126.png

Underneath are the cpu mask of both the machines that are different:

7127_7127.png

This is the second host:

7128_7128.png

As displayed in the error from the first screenshot is guys wrong on an ECX lvl.

Can someone explain and find me the proper cpu mask please.

And where i need to add this mask.

I also used this site for some extra info but that didn't help:

Are you using ESX 3.5 or ESX 4?

I am going to upgrade the hosts soon.

Well when you migrate to ESX4 you can try to create an EVC Cluster.

i know have tried this now also.

But when trying to create the EVC cluster a get 2 groups of each 3 ESX servers.

I want to be able to deploy all vm's on all ESX hosts, so i can also easy upgrade ESX to 4.0

That is why i really need to have that cpu mask.

And where i need to add this mask. You have to mask each vm in your inventory.

when adding the cpu mask displayed above it isn't possible to migrate the machine back to the other host.

It looks like the mask isn't backwards comatible.
