Matthew,

I had similar TSM DB backup issues and found this TechNote. I followed it and 
it fixed the slow backups.

Subject: Re: TSM 7.1 install on AIX problems

I just did the install last week and didn't see any issues with the
install script or memory dumps.  What version of AIX are you running?  I'm
on 6.1 TL 7 SP 6 (I updated from TL 7 SP 4 in order to do the TSM 7.1
install.)

I am seeing abysmal speeds during backup db commands (about half the
average speed I was getting before,) but that's neither here nor there.
Sigh.
