W3831 Unable to find any media // blank media

[securityforums]

Hi there

I currently have two jobs, one which runs daily which seems to work fine. The second is an archive which I run twice a week. I have setup two slots of my DLT to be under a new group, GROUP1 rather than 0.

The job is scheduled to run but always fails with

W3831 Unable to find any media.

In the backup options I have ticked:
Overwrite same media name, or blank media then ANY media
(the same as my daily backup which works fine)

The problem seems to be that under device manager the tapes arent listed.

I can make the backup work if I do a MOUNT / DISMOUNT or an inventory but why do I have do to this???
I dont have to do this with the daily backups, it does take quite a while to actually perform this operation on a 7 tape DLT autoloader.

Is there anyway to stop having to to this every time for the archive backup on group1, as I dont have to do it with the daily. Maybe a way of auto scheduling one of these before the archive?

Will give this is a try

*SIGH* more service packs from computer assoc for arcserve, not exactly the easiest ones to apply either.

(I originally posted this in another thread, but it seems relevant here as well.)

A few weeks ago our backup job began failing. Most of the failures were due to E3714 "Unable to write to media" but a few were due to W3831 "Unable to find any media". I had stashed some data on our server just before the failures began -- and this pushed the size of the data backup selection over the limit of our tape drive. I deleted the data that I stashed (it turned out to be corrupt, so I no longer needed it), and the errors went away.

I've noticed that ARCserve sometimes creates an entry in the activity log just prior to either of these errors instructing the user to insert another tape. (This only happened once on our server.)
