Dan, I think it's something to do with the nature of streaming tape drives: the tape transport can't position the tape to the tolerance required for overwriting. Overwriting did work on reel-to-reel tapes, but then it's embarrassing to admit I know that. Maybe you need to change users instead of changing tapes... -----Original Message----- From: midrange-l-admin@midrange.com [mailto:midrange-l-admin@midrange.com]On Behalf Of Bale, Dan Sent: Wednesday, August 29, 2001 12:27 PM To: midrange-l@midrange.com Subject: RE: SAVxxx SEQNBR(11) bombs if #11 already on tape??? This is a multi-part message in MIME format. -- [ Picked text/plain from multipart/alternative ] I was wondering the same, whether this only works with reel tapes. If so, it seems odd that IBM chose to leave the help text I referenced unchanged (even on our V4R4 box!), without at least some note that this only works for reel (or non-7208?) tapes. I mean, really, who uses reel tapes for backing up their AS/400 anymore? Regardless, it seems odd that this is an issue with any tape drive, don'tcha think? Go to sequence# 11 on the tape, ignore what's there, and start writing. What's so hard about that? <sigh> Making a mountain out of a molehill, I guess. Dan "there's just gotta be a way!"
