After we upgraded to vSphere 4.1, the SCSI adaptor of all our WINXP guests changed from LSI Logic Parallel  to BusLogic Parallel. This change should normally not create any warnings or problems it VMware Tools are up to date.

But after the upgrade all our WINXP guests got the following warning when powered on in the event log.

I then changed the SCSI adaptor back to LSI Logic Parallel and I now got almost the same warning.

I contacted VMware support and they told me that it was a known “feature”/”bug” and send me the following link to suppress the waring in the Event log.

There is two ways to suppress the warning.

Through vSphere Client

• Using the vSpher Client logon to your vCenter server.
• Poweroff the VM.
• Edit the VM’s settings
• Navigate to Options > Advanced > General
  
• Click Configuration Parameters
• Add the following rows, by using Add Row
  • If you have a BusLogic Parallel SCSI adaptor

  buslogic.noDriver = "FALSE"

  • If you have a LSI Logic Parallel SCSI adaptor

  lsilogic.noDriver = "FALSE"

• Click OK twice to close the dialogs and save the changes.
• PowerOn the VM

Editing the VMX file

• Open a SSH to the host ex. using Putty
• Navigate to the VM’s files (relpace with your own path)

  cd /vmfs/volumes/lun01/winxp01/

• Open the config file  in your favorit editor .

  vi winxp01.vmx

• Add the following line to the file
  • If you have a BusLogic Parallel SCSI adaptor

• buslogic.noDriver = "FALSE"

  • If you have a LSI Logic Parallel SCSI adaptor

  lsilogic.noDriver = "FALSE"

• Save and close the config file.
• PowerOn the VM

I haven’t tested if it possible to add the lines to the global config file on each host (/etc/vmware/config) for all VM’s..

I will test this next week.
