APAR Error Description / Circumvention

-----------------------------------------------
With tape multipath support, it is difficult to understand SAN
layout of a tape subsystem. A report should be presented that
shows the path layout.

CORRECTION FOR APAR MA44759 :
-----------------------------
Apply this fix to provide a new advanced analysis macro,
iotapepaths to produce a report.

CIRCUMVENTION FOR APAR MA44759 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


iotapepaths advanced analysis macro:
The first input parameter is a hardware resource name, one of
1. Blank        Report all tape resources
