Hi Nugget,
Thanks for your reply. On the second physical machine; if I add disk and select "raw device mapping" I will see all of the LUNs that are available to the first physical machine. This means that all HBA WWNs have been properly assigned to the storage volumes and both servers can see the shared storage. During the creation of my shared volumes/LUNs, I created a 10gig volume to use as a datastore for the RDM file. During the addition of the quorum volume to the first cluster node, I instructed vSphere to store the RDM on the 10gig volume that was mapped to both physical hosts. The RDM file was created. On the second physical host when I create a hard disk and specify "use an existing virtual disk", I cannot see any datastores, specifically the one created for the RDM file on the first host, other than the ones actually created on the second physical host. I was thinking that some other step is required to have the machines share their datastore information. Is vCenter necessary for this? I do not have vCentre. If not, what am I missing?
Thanks
GM
