I am planning to migrate two esx 4.1 hosts to esxi5.1 by wiping them and doing a clean install. Each host is connected to two iscis sans, with 4 luns from each san attached to each host. Each lun
is spanned over 3 extents. I am planning to vmotion (not storage vmotion)the guests from one host to another to do the upgrade. I am stuck on determining what will happen to the isci luns after I
upgrade the hosts to esxi5.1. It seems like I should just be able to reattach them, but I am not sure. Can I simply just re-attach the luns to the newly install 5.1 hosts and see all of the
vmdk's intact, or is there something I am overlooking?
And should the the vm's migrated to the other host continue to run on the iscsi san while I upgrade the host they were vacated from? It seems the storage should be removed from the process as the luns
should not remain attached to the host after it is wiped and the iqn's no longer exist.
Am I on the right track here? What am I missing?
