Migration from RAW device to Virtual Disk

[sposada]

when trying to cold migrate a disk raw device VM from EVA Storage to a virtual disk in a DS8100 it fail with the following message: "incompatible device backing specified for device ´0´" that LUN size is 510 GB and the message appaers when 100% is complete 3 hours laters. I define the block size 2 Mb in the Datastore, but when I Try to migrate a RAw of 100GB on same VM the migration works fine and I use the new Virtual disk without problems.

This could be a problem with maximum of storage migration?

Could you tell me if You know another way to migrate this Raw device to Virtual Disk?

Tks!!!

Have you tried VMware Converter inside the guest that has the RDM backend?

Hello,

Bring up a VM with the RAW disk attached as well as the target VMDK and then copy the data using the Guest OS within the VM from the Raw to the VMDK.

Maybe migrating the 510GB RAW LUN to a virtual disk on a 4MB blocksized VMFS will do the trick?

2MB block size allows max file size to be 512GB only, which may be to close to your 510GB RAW.... Dont know..

I would boot the VM with an Imagetool like Acronis TrueImage and migrate the whole partition.
