Hi Vinicius,
You need to use a unique Media Type for each autochanger, e.g. “LTO5-Library1”
and “LTO5-Library2”. These are arbitrary string values, the exact name doesn’t
matter. Bacula believes a drive in library1 is suitable for loading a tape from
library2 because the same Media Type is used for each.

Ben Roberts

Subject: [Bacula-users] Bacula Loading Tape at the Wrong Library
Hello everybody,
I'm new to Bacula, and i'm having a problem using different storages in a same
pool.
I have two HP Tape Libraries installed on the Storage (LibHP08 and LibHP09), i
tried to configure some jobs to access both libraries, but I'm having some
trouble with bacula accessing the wrong library.
For example, bacula tries to access volume "G00022L5" on slot 20 at LibHP08,
but it reaches the volume "H00011L5" on slot 20 at LibHP09. Basically, it tries
to get a tape on the correct slot, but in the wrong Library. It Generates the
Following error:
LibHP 3307 Issuing autochanger "unload slot 20, drive 1" command.
Warning: Director wanted Volume "G00022L5".
Current Volume "H00011L5" not acceptable because:
1998 Volume "H00011L5" catalog status is Append, not in Pool.
Then, bacula unloads the drive, tries to find the correct tape, but loads the
wrong one, generates the error again, and so on.
The job never completes, since it doesn't find the correct tape.
Some of my Pools:
Pool {
Name = machine-Pool-Weekly
Pool Type = Backup
Storage = LibHP08, LibHP09
Recycle = yes
AutoPrune = yes
Volume Retention = 34 days
}
Pool {
Name = machine-Pool-Monthly
Pool Type = Backup
Storage = LibHP08, LibHP09
Recycle = yes
AutoPrune = yes
Volume Retention = 1825 days
}

}
At bconsole, i executed the following:
update slots
There was some tapes at the wrong place, it updated the catalog, but the error
persists.
I'm Currently using Bacula v5.2.12, I've installed the Director and the Storage
on different machines, both of them communicating with no problems
Any ideas?
I also created a question at Serverfault:

Thanks in advance!
