Yes, they are write enabled...   One of the first things I double checked...

Have you flicked the switch on the cartridge to write enable it?

Subject: Initializing 3590 tapes?

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?

Lee
