No Option to Use SAN Migration
When you try to use SAN to migrate a virtual machine, only the network option is available, and the “SAN Explanation” indicates that there is more than one virtual machine on the same LUN.
Possible cause (or causes)
In non-clustered cases, LUNs are migrated through masking that prevents simultaneous access to the same LUN by multiple hosts.
Solution (or solutions)
Deploy or create only one virtual machine per LUN.
