Vmotion+RDM

Does anyone know if Vmotion will work fine with RDM set as "physical" mode? Also, can VCB be used to backup to backup VM with RDM LUNs? I am having trouble with finding documentation on this topics. Greatly appreciated if you can point me toward the right direction.

ESX 3.5 (build 110268)

Thanks.

VMware VMotion, VMware DRS, and VMware HA are all supported in both RDM physical and virtual compatibility modes. p.60 SAN System Design and Deployment Guide August 2008

VCB will need the RDM to be in virtual compatibility mode, so that a snapshot can be taken of it.

We have 3 physical mode RDMs connected to one of our guests and have no problems with Vmotioning that VM.

I do believe that using VCB on an RDM requires virtual mode RDMs.

Thanks vmroyale for your response. ! According to this VMware document, Vmotion will work with RDM in either physical or virtual mode (page 12). Maybe the document is not up-to-date with the current release...

Thanks formulator for your response ! I'll setup a test VM with RDM and try it out.
