I have spent hours and hours trying to get TSM server 5.2.2.0 on AIX 5.1
to define the PATH to the above tape library.

Every time I click on defining the PATH (/dev/smc0) to this library, TSM
goes off and spins for a while, eventually coming back with some kind of
error about being unable to communicate with the device.

I have repeately removed and rediscovered the library and drives
(restarted the TSM server numerous times).

Played with tapeutil. It can successfully open the tape drives themselves,
no problem.

LSDEV says everything is happy:  smc0 Available 1D-08-01 IBM 3583 Library
Medium Changer (FCP)

So, what am I missing ?  What am I doing wrong ?
