Does drive APPLICATION level encryption work on WORM? So if I make my new worm devclass WORM=YES and DRIVEENCRYPTION=ON I'll get encrypted WORM media.

The redbook "Implementing IBM Tape in Unix Systems" provides some insight... "Because Tivoli Storage Manager can distinguish between WORM and R/W cartridges (assigns "media type" of 412 for WORM cartridges and 411 for R/W cartridges at the time of check-in), you can have both WORM and R/W cartridges in a single logical library just by defining device classes, one with WORM=yes and the other with WORM=no." There are some things which TSM knows "under the covers". Media type is revealed in the output of the Query LIBVolume command. Richard Sims at Boston University
