Moving RDM to physical host

Hello,

Wanted to know if there are any specific restrictions about moving a RDM (physical compatibility mode) to another physical machine?

Say I have a LUN assigned to a Windows VM as RDM. Can I assign the same LUN to a another physical Windows host?

Thanks,

Rupak

As long as its physical mode, yes doing what you mention is fine.

Many customers (including some of my own) use this method as a way to prove to virtualization-hostile vendors (Oracle, MS) that problems are not VMware-related - they just slide the device(s) over to a physical host, prove that the problem still exists and demand the vendor continue troubleshooting.

Update on original post:

Not saying terms of clustering. It's like un-assigning the LUN from the VM and assigning it to a physical host.

Thanks. I would assume that this is not possible if it's in virtual compatibility mode.

It is *possible*, but would be dangerous. What if there was an outstand VM-level snapshot. You'd end up with inconsistent data.
