RDM Virtual Machines Show as VMFS Virtual Machines After Being Migrated from ESX Server 2.x Hosts to ESX Server 3.0.1 Hosts Using VMotion
Details
Why does a physical RDM virtual machine that I migrated from an ESX Server 2.x host to an ESX Server 3.0.x host using VMotion appear as a generic VMFS virtual machine?
Solution
When you migrate a physical RDM virtual machine from an ESX Server 2.x host to an ESX Server 3.0.x host using VMotion with datastore migration, the VI client displays this physical RDM as a generic VMFS virtual machine.
To resolve this problem, power off the virtual machine and upgrade the virtual hardware.
