The question “How to remove a host from your Virtual SAN cluster” has now popped up various times, so I figured I would write a short article around what the current procedure is. It is fairly straight forward to be honest, here we go:
- Place host in maintenance mode
- Delete disk group when “maintenance mode” is completed
- Move host out of the cluster
- Remove the VSAN VMkernel (not a requirement, but I prefer to clean things up)
That is it, now you can re-purpose the host for anything else.
One thing to add Duncan. If VSAN is setup to automatic mode you have to change the setting to manual in order to be able to have the delete disk group icon available.
good point
My host is totally dead, I can’t manage it anymore. In this way, How could I remove it from vSan?
