Hello,
I would start by reviewing http://www.vmware.com/pdf/vi3_35/esx_3/r35/vi3_35_25_admin_guide.pdf for information on how to create RDMs. There are at least 2 ways, one using vmkfstools and the other using the VIC.

In general,
Create a LUN on your SAN and present it to your host(s). Rescan your host(s) so that it sees the new LUN, but do not create a VMFS partition.
Either create or modify an existing guest and Add a hard disk - when selecting a disk, choose the bottom option- RAW Device Mappings.
This works for VC2.5 U2/U3 and ESX 3.5 U2. Not sure about other versions.

The procedure provided by abaum is correct for ESX 3.0.X/VC2.0.X as well. However, if you havn't already, familiarize yourself with the different types of RDM access (i.e. physical vs virtual). Physical does not allow Vmware snapshots.
Also, double verify the vmhba path of the newly presented LUN before connecting the LUN to a VM.
