I decided to use this as a basis for experimenting with tapes since we
haven't got to that yet. Using SuSE SLES7, I had a running system.
>From another VM userid on the same system,
VMTAPE MOUNT SCRATCH DSN Linux.tape.test ( retpd 5 label nl
CP GIVE 181 to LINUXSRV 181
Then, from root on the linux machine
insmod tape390 tape=181 Using
/lib/modules/2.4.7-SuSE-SMP/kernel/drivers/s390/char/tape390.o
>From the 3270 console of the server, I see

(Confirmed /dev/ntibm1 really is there)cd /hometar -cvf /dev/ntibm1
./patchestar: /dev/ntibm1: Cannot open: No such devicetar: Error is not recoverable:

Obviously, I'm doing something wrong. Any idea what?
