Multipathing within vmware

Hi

I try to create two virtual paths to one disk to simulate multipathing. I have the following configuration:

#Locking

disk.locking="false"

#HBA

#Internal

scsi0.present = "TRUE"

scsi0.virtualDev = "lsilogic"

#External

scsi1.present = "TRUE"

scsi1.virtualDev = "lsilogic"

scsi1.sharedBus="virtual"

#For the second path

scsi2.present = "TRUE"

scsi2.virtualDev = "lsilogic"

scsi2.sharedBus="virtual"

#DISKS

#Internal

scsi0:0.present = "TRUE"

scsi0:0.fileName = "RHEL4U3-000001.vmdk"

scsi0:0.writeThrough = "FALSE"

#External to share

scsi1:0.present = "TRUE"

scsi1:0.fileName = "data.vmdk"

scsi1:0.mode = "independent-persistent"

scsi1:0.deviceType = "disk"

scsi2:0.present = "TRUE"

scsi2:0.fileName = "data.vmdk"

scsi2:0.mode = "independent-persistent"

scsi2:0.deviceType = "disk"

redoLogDir = "."

But this does not seam to work. I see two disks sdb and sdc which are not identical, but they should be identical.

Any ideas?
