My advice is to not use the GUI. Until IBM eventually decides to make a working
GUI there should be a big red warning stating that if you are going to restore
more than a few files the CLI must be used. (And not even then can the GUI be
trusted [1] )
I experienced the same as you. Used the GUI when restoring a few million files
and the TSM-server started an endless task of mounting and dismounting volumes.
However with the CLI it worked fine after a period of NQR processing. Not sure
why the different behavior(I did not tick the "Disable NQR restore in the GUI".)
