My opinion is that encoding as much of your logic as you can in TSM schedules
and scripts saves you dependencies, and increases our common understanding of
"how we do things".

If the minute-to-minute details of your TSM servers' management depend on some
outside scripts, then you're really off in the weeds as far as best practices
are concerned: You're a population of one.  If you use an aftermarket
application, then you're part of a larger group, but you're still vulnerable
if any of your products goes wrong.

So I use PERL code outside of TSM to translate configuration data from one
large XML file into lots and lots of scripts, and then I use that repeatable
process to change my config, but if I don't touch the servers, they just keep
on running, migrating, reclaiming, etc.


Below I've included an edited example, one of my server stanzas.  From that
information, and with reference to the running server, I generate a laundry
list of scripts:

Turn on/off  migration for stgpools of devclass X,Y,Z
Start/stop migration for stgpools of devclass X,Y,Z
Start/stop reclamaition for stgpools of devclass X,Y,Z
Backup the database
Backup the devconfig and volhist
Blow away all existing schedules
Define schedules

etc.
