I have a VSAN 7 cluster with mixed CPUs… EVC mode was not enabled when it was created. We’ve only recently added newer CPUs that can’t vmotion to the older CPUs. So I want to enable EVC mode. I’ve scheduled a maintenance window to power off all VMs on the cluster so that I can set the EVC mode.
But the vCenter that manages the cluster is in the cluster. I have another cluster that I can run the vCenter for this cluster on.
I can’t Cross vCenter VMotion it … EVC modes are not compatible.
So my plan is:
I’ll then be free to power off all VMs on the first cluster, set the EVC mode, and power the VMs back up.
(This cluster is only for VDI, and doing it off hours when barley in use..)
Does this seem like a viable plan? Given the fact that I can shutdown all the VM's, this seems like the simplest way to get it done.
Its a VSAN cluster, so I want to avoid removing hosts from the cluster, etc...
i have a similar situation: A cluster (evc disabled) with 2 hosts with uncompatible CPU's. Only 1 uncritical vm is running on the host with highest CPU gen. So i think i delete that 2nd host from the existing cluster and make a new cluster with evc enabled and then follow the same procedure like you did?
