GTF I/O tracing
PAV is compatible with GTF I/O tracing. When a device number is specified for a GTF I/O tracing
operation, GTF determines if the device is a PAV base device and automatically includes the alias
addresses currently assigned to the base device.
For more information on GTF I/O tracing, see the IBM document OS/390® MVS Diagnosis: Tools
and Service Aids, SY28-1085.
