Hello,
I am downgrading the EVC mode to Westmere to comply with an older generation of host we are adding to the cluster.
To do this, I currently have two clusters created, on which is production and has two hosts using sandybridge.
the second cluster has one host in it and will be westmere generation.
I am aware of the procedure found here:VMware KB: Enabling EVC on a cluster when vCenter Server is running in a virtual machine
My question is, rather than vmotioning all the machines to another hosts. is it possible to shut down all the virtual machines on a host, put it in maint mode, disconnect the host, move it to the Westmere cluster enable it, and then power back on all the virtual machines?
I am aware I will still have to disconnect and reconnect my vcenter server, but I would like to avoid having to vmotion a large amount of machines if I can find downtime to shut them all down. and have them move with the host.
is this idea possible?
