Base system is Z/VM 5.4.
I'd like to trace all i/o, interrupts, etc for a 3490 tape drive.
I am ipl'ing the IPL DDRXA from the S disk and defining the output as
181 3490.
The trace set looks like this:
NAME VTAP (ACTIVE)
1 I/O FROM 0000000000000000-FFFFFFFFFFFFFFFF
HEX 0181
TERM PRINT RUN SIM CCW IODATA 0008
SKIP 00000 PASS 00000 STOP 00000 STEP 00000
CMD NONE
My trace command is:
CP TRACE IO 181 CCW INS INT BOTH RUN
I've used various other combinations of TRACE SIO and TRACE SSSCH and
etc... with no happiness.
I can get the TSCH and SSCH commands to appear and nothing else.
What can I do to get ALL the tape i/o for address 181 to show up?
Thanks.
