I found it by searching for "3490" and then looking for "Reference" in the title. I think that's the last time we published the command interface to tape drives (1992). The 3590 Hardware Reference describes only the SCSI interface. > After reviewing the sense data documentation and suggesting that they > turn on bit 1 of sense byte 2 (The control unit is in communication with > the device), success was achieved. That's bit 1 of sense byte 1. :-) Also I see that after a successful rewind/unload, the SENSE format should be format 22 with ERA 52. I have no idea if it should have INTERVENTION REQUIRED turned on or not. <twilight zone theme plays> Alan Altmark z/VM Development IBM Endicott
