Hi,

the problem is resolved, thanks to Mr. Fink from Austria !!

ADSM 2.1.5.13 needs 

Atape.driver               3.1.1.0  COMMITTED  IBM AIX Enhanced Tape and
                                               Medium Changer Device Driver
when using a 3494 tape-library

atldd.driver               3.1.0.1  COMMITTED  IBM Automated Tape Library
                                               Device Driver


The following combination seems to work as expected

  Atape.driver               3.2.0.6  COMMITTED  IBM AIX Enhanced Tape and
                                                 Medium Changer Device Driver
  adsm.server.com           2.1.5.13  APPLIED    ADSM Server Common
  adsm.server.dev           2.1.5.13  APPLIED    ADSM Server Device Support
  adsm.server.util          2.1.5.13  APPLIED    ADSM Server Utilities
