We are starting the process of virtualizing the network adapters on our HACMP cluster members.  Since each virtual adapter is supported by two real NICs (primary and backup) the idea is to have only one virtual adapter per network on each HACMP member.  Up till now we've had two NICs per network (with two networks) on each cluster member.  Does anybody have any experience doing something like this?  I'm wondering if anybody has any tips or valuable experiences to share.
