Troubleshooting Virtual Machine Conversion Issues

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 causes

In non-clustered cases, LUNs are migrated through masking that prevents simultaneous access to the same LUN by multiple hosts.

Solutions

Deploy or create only one virtual machine per LUN.
