I am not the one who setup these hosts , but all host in a cluster , we have 4 hosts one of the host needs some part replacement , so we have to vmotion all the VMs from it , Vmotion went fine for all the machine except on VM I got this error :
Unable to migrate from "ESX1" to "ESX2" : virtual machine is configured to use a device that prevents migration : device "SCSI Device1" is a raw disk , which is not dupported
Same massage but SCSI Device 2
I open the VM sitting and found 1 SCSI Device 1 and 2 , and path is /vmfs/devces/genscsi/vml.000001212212110000045445450 , in front of each device under summary column.
Just to let you know , this VM used as a backup server , connected to a IBM tape library.
Any idea how to migrate this VM .
rayan68,
Some questions for you
- Do you have the tape library mapped as a raw disk to the VM?
- If yes, then are all hosts in the cluster able to see the tape library?
- Also, are all hosts able to see the vmfs lun on which the vmdk descriptor for the raw disk resides?
- Finally, this thread might be of help.

If I go to hsot -
Storage Adapters -- highlight vmhba0 in all hosts I can see that they see everything same as it looks in the picture
From all hosts if I go to configuration -
Storage Network -- and click vmhba and can see the same configuration
From all hosts if I go to configuration -
Storage Network -- and click vmhba and can see the same configuration
I can see that the tape drive is connected to vmhba0 (is that correct?)
What about the vmfs volume which houses the vmdk descriptor for the raw disk?
What do you mean ,I checked all of them and they all look they have the same configuration, I also try to add te same SCSI Device (Tap - IBM) to one of te testing host in deferent host in the same cluster , and try to vmotion it from this host to the host 4 but got the same massage ,
rayan68,
- What does your VM configuration look like? Do you two raw devices connected to the VM? (i.e. what are the SCSI1 and SCSI2 devices?).
- I'm assuming that all ESX hosts are presented the tape device with the same LUN ID (ref: Unix-Sysadmin's last comment on this thread.)
- Also, take a look at what rt7500 mentions here. Seems like you might need to remove the device from the VM, rescan all hosts and re-add the device to the VM.
