VMware – Incompatible device specified for device „13“
I recieved the following error message when cold migrate virtual machine with RDM (Raw Device Mapping) from Fujitsu DX90 datastore to the new datastore Fujitsu DX200 with SSD drives. The problem was limited to „Configuration file“ of affected VM. No problems detected with Hard Disk (OS – virtual drive .vdmk) migration.
VMware ESXi 6.0.0 4192238. Firstly i thought that, this error means problems with DVD drive or Floppy Disk drive, so i removed it both from affected Virtual Machine.
But the situation was exactly the same as before still error message „Incompatible device specified for device „13“„. The migration job stopped on 98%… so i removed – not deleted from datastore RDM (Raw Device Mapped) disk (totally 3 disks) from the affected virtual machine, migrate VM config file to the new datastore and added back 3 RDM disks.
