Building an MS Cluster with VMWare Workstation 4.5.2

I used to be able to build clusters in VMWare Workstation 4, I'm sure, but when I recently tried it didn't seem to work any more. I found someone (sorry - lost the URL) on the VMWare forums who claimed to have created one on VMWare workstation 5. I tried thier suggestions on VMWare 4.5.2 and with a few changes it worked for me. I created the quorum (100MB) and shared disk (2GB) as fixed size SCSI devices.

Here are the important lines from my node_1.vmx file:

diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"

disk.locking=FALSE

scsi0.present = "TRUE"
scsi0.virtualDev = "lsilogic"
scsi0:0.present = "TRUE"
scsi0:0.fileName = "Disk1.vmdk"
scsi1.present = "TRUE"
scsi1.virtualDev = "lsilogic"
scsi1.sharedBus = "virtual"

scsi1:1.present = "TRUE"
scsi1:1.fileName = "..\shared\quorum.vmdk"
scsi1:1.redo = ""
scsi1:1.mode = "independent-persistent"
scsi1:1.deviceType = "plainDisk"

scsi2.present = "TRUE"
scsi2.virtualDev = "lsilogic"
scsi2.sharedBus = "virtual"
scsi2:1.present = "TRUE"
scsi2:1.fileName = "..\shared\shared.vmdk"
scsi2:1.redo = ""
scsi2:1.mode = "independent-persistent"
scsi2:1.deviceType = "plainDisk"
