Lee, That sense field interpretation is only valid for 3480/3490 tape. The C0 in that field means this is a 3590/3592 sense format. The 3590/3592 ERPA code of C0 or D0 means you have to look to sense byte 6 to determine the error. Either the Tape device is defined incorrectly as the 3490 or this is an IBM bug that doesn't process the 3590/3592 sense data correctly.
If the latter, I would report the error to IBM.

Hi all, I feel a little dumb.. It's so long since I used a tape, and even longer since I created a tape, I think I'm missing something... Is there a way to initialize a brand new 3590 tape on VM? Everything I've tried (TAPE WTM, DDR, etc.) gives me: DMSTIO2139I VDEV 181 SENSE gives ERA/RAC= C0; cartridge may not be valid for I/O and the return code means: X'C0' Logical WRITE protection exception The MVS, sorry z/OS guys run IEHINITT on the same batch of tapes in the same drives and they can use them. So I know the tapes and the drives match... They tell me I need to initialize them, but I'll be darned if I can find anything in the VM manuals. And I really don't want this small set of VM tapes in the z/OS libraries... What am I missing?
