How to attach existing RDMs to a new virtual server

I will be rebuilding a Microsoft Cluster that uses several RDMs fore the shared storage.  What I am uncertain of is how to find the drives once I am ready to attach them to the new servers.  What do I need to capture or record so that I can add the same devices to the newly rebuilt servers?  With VMFS it is simple, but I am not sure for RDMs.  I tried searching for this but was unable to locate any help, so apologies if this has been discussed.  I have very limited experience with raw devices.

Thank You

Basically all you need to do is to know, which RDM (LUN) you have to map to the VM and which virtual SCSI ID you assign to it. This has to be the same for both virtual cluster nodes.

ThanK You Andre,

how do I tell which LUN it is?  Is there a place I can see this?  I was not the one who set this up originally.
