This touchfile should be used with great caution, AND PROBABLY
SHOULDN'T BE USED AT ALL. The NetBackup position checking logic is
there for a very important reason, to help IMMEDIATELY detect an
improper tape device setup that could result in data loss.
(specifically the scenario where improper SCSI reserve/release
configuration on a tape SAN results in one host rewinding a tape
drive that another host is simultaneously writing to)
Thomas, I would claim that your status 86 problems are probably
hardware-related, and this touchfile won't actually make any
difference at all. (any device-level errors that accompany these
NetBackup errors?) In any case, I'd suggest you open a Veritas
support case before you put this touchfile in place.

Hello all,
I have a handful of policies defined for clustered file systems that
are consistenetly failing when attempting full backups. They are
erroring with status 86. I've tried forcing them to use diferent
drives, tapes, etc.
A third-party vendor we deal with thought there was a way to disable
the media positioning check by touching a file under openv/netbackup
similar to DISABLE_MEDIA_CHECK...but he wasn't sure of the exact
syntax.
Is anyone out there familiar with this file?
Thanks,
