[ClusterLabs] clustering fiber channel pools on multiple wwns

on illumos, I have a way to cluster one zfs pool on two nodes, by moving ip,pool and its shares at once on the other node.
This works for iscsi too: the ip of the target has been migrated together with the pool, so the iscsi resource is still there running on the same ip (just a different node).
Now I was thinking to do the same with fiber channel: two nodes, each with its own qlogic fc connected to a fc switch, with vmware clients with their fc cards connected on the same switch.
I can't see how I can do this with fc, because with iscsi I can migrate the hosting IP, but with fc I can't migrate the hosting wwn!
What I need, is to tell vmware that the target volume may be running on two different wwns, so a failing wwn should trigger retry on the other wwn: the pool and shared volumes will be moving from one wwn to the other.
Am I dreaming??
