After reading this http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1015292
and considering we are using local storage for the linked clone pools as per this paper http://www.vmware.com/files/pdf/view/VMware-stateless-virtual-desktops-ref-arch.pdf
I dont see how we can put a host into maintenance mode, after it has been evacuated of vm's with the exception of replicas without breaking vm's on other hosts that rely on the replicas.
Will the pool create another replica and link the currently running vm's to that new replica? Is this documented?
