comment VMware Virtual Machine Clustered Filesystem Setup
Worked well enough to point me to the crux of the solution. Short version would be, create a new disk pointing to an RDM on a different scsi device. so say SCSI1:1, VMware will create a new SCSI controller automatically and on that controller set shared disk access as required.

comment Is there a way to clone an existing VM on an ESXi server without having to re-import it?
if it is a one hit the trial may work for that.

I have a LUN and can point a single VM to that LUN using RDM. That machine can then access that disk without issue. VMware however then greys out the RDM option on new disk creation because that LUN is in use. Basically it seems limited to a 1 to 1 ratio of LUNs to VMs. Linking the same disk with the RDM mapping to multiple machines faults with a disk lock error as normal.

NFS would introduce a single point of failure in the NFS server. The SAN has 4 fail-over paths, each ESX host has 2 HBAs and I would like to maintain that level of redundancy. Any solution involving multiple NFS servers would put me back to the original issue. Additionally any file sharing arrangement would introduce CPU overhead and latency into the equation that I would rather avoid. That said I am investigating if the SAN can be an iSCSI target then use the software initiators inside the VMs.

updated the question for clarity; 3 ESX hosts have 5 VMs running; I require a single disk device accessible by each of the 5 VMs.
