Hi Geoff,

I was under the impression that for multi-path you need either 2 distinct 
connections and you can have failover one connection fails, or 2 
block-syncronized filers which helps you out if one filer dies.

You can do dm-mulitpath with only one path. It would basically give you an extra layer to retry and queue IO at in case something happened. The scsi/iscsi layer only gives you 5 retries.
