Hi,
I have some things witch could be possible bugs.
First:
Configured are one virual autochanger of type file and one physical autochanger
of type tape. There is one pool for every changer.
I use bweb, so i can see some informations at a glance, for example the
in-changer flag.
Sometimes i get an error when changing the volume in the virtual autochanger.
At this time, the in-changer-flag from one physical medium (tape) ist unset.
After a while, many medias have an unset in-changer flag.
Here is the error message from the job, but i don't belive this is the
originaly reason:

As you can see, loading the required volume is no problem. I think, the error
message is NOT the problem of this behavior. I believe i have seen this
in-changer-flag setting sometimes when a media is changed. The bug is, that the
flag is set to the wrong media. It is set to an physical media from the
physical changer, which is an other pool. But the physical Volume has the same
slot-Number!
Second:
Migration jobs migrate jobs twice. In our environment every three hours a
migration job is beeing triggert. After that three hours it is possible, that
not all migration jobs are finished, so some jobs have not the status "M" for
migrated jobs. A new migration job is starting and those not completed jobs
will be queued again. Thats ok, because at this momenten the flag "M" for
migration is not beeing set to the job, as i wrote. Now the jobs from the first
migration-job will be executed and the status will be set. When the second
migration job for the same jobid is on the line, it is beeing migrated again,
although the job-status for migration is set!
Better would be to look at the beginning of a job which job-status is set.
If you thing these tings are bugs i would report it with as many informations
as i can provide.
Mit freundlichem Grüßen
Sebastian Lehmann
