I would be interested in anyone's experience in converting to Magstar
     drives under the MVS ADSM server.  We are currently trying to convert
     to Magstars defined in compat mode within an STK silo.

     When we define the drives as devtype=cartridge, it works great but we
     seem to only get 10G to a cartridge.  When we use devtype=3590, we
     fail because ADSM doesn't see the UCB as a 3590.  This is a V3 server.

     Any ideas?
