Do you know if the test is to see if the path has 'transport mode' yes ? In our case, I believe that transport mode showed yes for the dasd paths -- even though microcode levels weren't sufficient on the HW to support HPF and created errors on Linux. So this option doesn't really serve to disab

Ann, There's a new feature on z/VM 6.2, that defines a CHPID appropriate for virtualization, named CHPIDV.  Once you define that (OPTION CHPIDV ONE), z/VM will test the possibility of using zHPF outside the Guest:  if the environment is appropriate, TCW calls will be made; if not, CCW (non zHPF)
