Creating a Raw Device Mapping

Hello VMware communities!

I have vSphere, and I am trying to share a LUN that i created on my san between two VirtualMachines.

The VirtualMachines are located on two seperate ESX hosts.

Since VMFS can support clustering and access to a disk from multiple locations- i want to create a RDM device for the two virtual machines. This should allow them to share the LUN storage i set aside for them off the san. However, the RDM option is blank when i try and add a hard drive. Any clues to why this is not enabled?

Or,

Do I have my configuration wrong?

Thanks for any reply.

First to all be sure that your RDM LUN is visible on ESX / Configuration /Storage Adapter.

If not, do a rescan, and if still is not visible is a problem with the configuration of your storage.

Then for guest cluster configuration see:

Thanks Andre,

I had the shared storage already setup as a Datastore... so i removed the data store and the RDM was available. I guess the word noob comes to my name 😐

O well, another day, another thing learned.

Thanks again.
