Just in case this ever keeps anyone else from banging their head against the wall for a few minutes/hours:
Lots of TSM manuals and IBM manuals about using tape libraries with open systems refer to GC35-0154 as a must-have manual. It's been superceded by GC27-2130. I'm sure the rest of you are sharp enough four days a week to figure that out as soon as you find GC27-2130, but on a Friday, it took me longer than I expected, thanks in part due to an utter lack of notes on ibm.com to that effect. GC27-2130 is on ftp://ftp.software.ibm.com/storage/devdrvr/Doc/ as IBM_Tape_Driver_IUG.pdf. For the record, Nick
