Eric,

Could it be that there were other sessions running to the next pool due
to settings in the bcg's so there were no more mountpoints for 10
migrations but only for 2?

Regards,

  Stefan

Hi Remco!
The high treshold is set to 5 because we want the data to go to virtual
tape a.s.a.p. This weekend the diskpool went to 100% again because of
the strange migration behavoir. The pool contained data from 100+
clients, but still no more than 2 migrations were running....
The tape deviceclass has mountlimit=drives which is 30 drives.
Kindest regards,
Eric van Loon

Have you ever considered increasing the high threshold? IIRC TSM won't
start new automig processes when migration is already running, and
will only start as many processes as there are different clients
having data in your pool. Also, check out your mountlimit on the tape
devclass.....

Furthermore, your disk pool might not be fast enough to keep your
drives streaming.
