RDM - vmotion

[maniee]

is it possible to do vmotion/storage vmotion for VM with 2-RDM disk mapping ( both in case of physical vs virtual compatibility mode)

Regards

Maniee.

vMotion - yes, provided that your RDM LUNs are visible from target host too. vMotion won't be troubled.

Storage vMotion - see following quote

• Physical mode RDM pointer files can be relocated to the destination datastore, but physical mode RDM data cannot be migrated to a VMDK disk using Storage vMotion.
• Virtual mode RDM data can be migrated to a VMDK disk with Storage vMotion by selecting the Disk Format from Advance View, provided sufficient licensing is present.

following KB has all the answers you seek

Hello Maniee,

Yes we can migrate the virtual machines but it requires a power off virtual machine.

Power off virtual machine.

Remove rdm and remove from disk.

vMotion the virtual machine with C drive.

After the vMotion connect the RDM again to the virtual machine.

Please let me know if you need any further information.

Thanks
