The Question is:
Keep getting "tape not valid ANSI format" when trying to mount new tapes with
TLZ09 tape. Nightly backups work fine with old tapes.
Bought new tapes (both Sony and Maxell) DDS-2
Tried all the normal init options, mounting with /over=(id, label), etc.
New tapes don't work. Old tapes are fine.
Any clues? Is there a special init I have to do to a new tape?
The Answer is :
Please do ensure consistent use of the /MEDIA_FORMAT=COMPACTION option
on all of the DCL commands involved with initialization, MOUNT, and
Without the details on the BACKUP, INITIALIZE, MOUNT, and related DCL
commands used, it does initially appear that you have media problems
with these DDS cartridges.
Your OpenVMS version is outdated and badly in need of an upgrade.
Please seriously consider an upgrade to OpenVMS V7.2-2 or V7.3-1 or
(as available) later. There have been various changes and enhancements
in the areas of device handling and device performance throughout these
more recent OpenVMS versions.
