Hi,

this is the link: http://www.vmware.com/support/gsx25/...nable_gsx.html (same for VMware server)

Basically you need to edit the .vmx file under the host machine, then add those things to get shared scsi bus. (Windows/Linux does not matter)

You don't need any HW to do that. My first cluster was runnig on my laptop with an external HDD. 4 machines with 2Gb ram.

So the important things are these:

- scsi1.sharedBus = "virtual"
- scsi1:1.shared = "true"
- disk.locking = "false"

It worked for me when I tested Exchange 2003 and SQL server 2004.
The nodes were able to swap the disks and I still were able to use the main cluster with the node1's data on the shared disk on node2 and the quorum disk too.

So it is good.

Hi,
Just the server able to use the shared disks properly. The workstation does not able to do that.

Actually I have not use the workstation for quiet a while but that was the main reason to change it to the server one.
