Hi All,
I recently went on a VMWare training course and found out about changing my SCSI controllers over to ParaVirtual. The way I was taught to do this would be to add a second ParaVirtual SCSI controller to ID 1:0 to get the driver added to the operating system then shut the system down and switch the main controller (ID 0:0) from LSI Logic SAS to ParaVirtual and then remove the second controller that you added for the driver. I have done this on a couple of servers but most are coming up with the following error when trying to add the ParaVirtual controller:
An error was received from the ESX host while powering on VM %name%.
Failed to start the virtual machine.
Module DevicePowerOn power on failed.
Unable to open the SCSI device '/dev/genscsi/t10.DP______BACKPLANE000000' (scsi1:0): Failed to lock the file.
Does anyone know why this might be? I'm using version 5.1.0
Thanks
Duncan
