In the meantime I found the solution for my problem and so I anwser to my
own request:
The REGISTER NODE command have a new parameter MAXNUMMP under TSM 4, with
a default MAXNUMMP=1. My new configured servernodes could not mount more
than 1 Tape. The servernode, which I configured under TSM 3.7, got a
MAXNUMP "Unlimited" with the upgrade to TSM 4.1.
A backup on virtual volumes needs 2 drives, when MAXCAPACITY is reached
and the last file is continued on the next volume.
