How to share disk on 2 virtual linux machines

I tried to configure Oracle RAC on 2 VMs, my question is how can I create a shared disk for both VMs.

I have vCenter installed and has one ESX 4.1 host.

1 Solution
There are 2 options to do that:
- Using Raw Device Mappings
- Using SCSI Bus Sharing

Seeing as you only have 1 ESX host it might be useful to use SCSI Bus Sharing option.

See the attached image

A third option exists if you have a machine that can provide an NFS share. This is quite easy to implement.

BTW, just out of curiosity: what are you trying to gain from this setup ? There's no advantage in using Oracle RAC if you only have one physical server.

Sorry for the late response. I only have one host and I'm trying test RAC installation.
