Your environment is very similar to what I recently configured, but  I
didn't experience any problem you are having now.
I am just listing the steps I used and perhaps you might have made a typo
or something.
AIX 5.2, 3583-L72 library with 3 tape drives, SAN attached, TSM 5.2.2

Also 3583 can be configured as Multi or Single path.  Which took me a while
to understand this.   If your library is configured as single path, then
you will need  Library firmware made for single path or configured as multi
path then you will need Library firmware made for multipath.  I would
double check you have the right firmware.

Configuration of the library and drives.
After the library is defined, must define path before defining drives.
Also after drive is defined for devclass will be unknown until path for the
drives is defined.

You can use these commands to get more information about the drives and/or
library changer.
This command will also give you WWN information if you are connected via
fiber.

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 ?
