GTF I/O tracing
Parallel Access Volumes are 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 Parallel Access Volumes 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).
