What exactly is a near line volume?

If add '-q near' to mminfo command what will it do differently?

Thanks.

A volume that is in an addressible jukebox. It may not be mounted at
the moment, but it can be mounted without operator intervention. An
offline volume is not in a jukebox, and cannot be mounted by Networker.

It will only show nearline (jukebox) volumes.

Hello,

I have a question about nearline volumes.

We eject all our full tapes from library and also remove them from CAP. So the tapes are not there physicaly. We have a script which is updating locations, but first it finds out whether or not we have tape in a library (via -q near). If the tape is in library, but the location differs, it prints out an error message.

The problem is we are still getting these error messages, because when i run
"mminfo -q near -xc, -r volume " I still have these volumes on the list even if they are not physicaluy in the library... Our offsite storage guys confirmed, that tapes arrived and are there. So its no way we can have them in library.

Any ideas why is this? How is it possible? And how can I convince our library to show only the tapes that are really there? how mminfo determines whether the tape is in library or not?

Are you using nsrjb or NMC to withdraw the tapes? Or, are you using a
non-NetWorker command?

I would suggest using sjirdtag to verify the contents of the library instead
of mminfo, if possible. There are a few scenarios where mminfo isn't
properly updated, while sjirdtag is almost always correct.

How do you eject your tapes from your tape library?

Aaron: I know, via sjirdtag, everything is OK. Tapes that are marked as nearline in mminfo are not visible via sjirdtag. But the problem still persists. We need to have mminfo updated, cause its the best way to update locations via script. On other libraries, we have no problem with it

we use nsrjb to withdraw tapes via script.
