The 1st is due to the Source being Block I/O and Destination File I/O so this can be ignored
The 2nd 2 where both in Block I/O but I deleted them and recreated in File I/O. Both SANs have 384Mb vmalloc and the volumes are the same size. They are assigned Source and Destination but ot the Source SAN I can't see the Destination volumes that corespond to the source.
