Well, two answers - You could indeed write a pseudo-RA which monitors the DM-MPIO devs, or feed their status directly into the CIB from multipathd (via an unmanaged resource), or monitor the devs externally and modify a node attribute accordingly (ie, "connected-to-san") and create a rsc_location dependency. This is going to involve writing code. Or you could simply assume that the likelihood of the DM-MPIO devs being unavailable is really low (afterall, MPIO implies redundant connection); if they really aren't available where the cluster tries to instantiate the DomU, the start will simply fail and be retried on another node within 1 second or so. Personally, I would probably go with the second choice; lower complexity.
