vSphere 5.5 how to pull in RDM drives on 2nd VM


I have 2 MS Server 2012 VMs created and have several RDM disks pulled into first VM via the vCenter Web Client 5.5.  The first node was no problem, but I can't pull them into the 2nd node.  If I try "add new RDM disk" they're not listed.  I tried add existing disk and I can see the vmdk files, but I get file locked error.  I've read that I can use 0:x SCSI controller, so I tried from scratch installing a second SCSI controller with no effect.  I've tried using virtual instead of physical and get same result.  

I've also seen you need to select shared bus in the scsi controller properties, but it's greyed out.  

Basically, I'm looking for guidance to on how to pull the disks into both VMs successfully.   I've scoured the internet and can't find anything pertaining to 5.5 outside of the VMware documentation which isn't helping so far.  

Thank you for your help!

Have you followed the exact steps as per the cluster guide, Page 16

In my experience the RDM disks cannot be on the 0:x controller.  Place all your RDM drives on an added controller and make sure you use the same scsi id on both of the clustered vm's.

I needed to shut down the VMs to change the bus sharing setting on the 1:x controllers on each VM.  It was grayed out and unchangeable with the VMs running.  After doing that, was able to pull drives in correctly.  Thanks!
