Many Thanks for the answer Marcelo.
Can we do vmotion between hosts in a cluster communicating with the same storage(having same luns), but one host has iscsi and other FC? we are waiting for the HBA adapter meanwhile we will be using iscsi, but later we may have to connect one FC and other Iscsi and do vmotion then connect FC to other host. As per my knowledge, it should work as both host have common luns visible.
