Is this its correct behavior?
It always behaved like this for me at least. > I load the tape in Slot 1 into the drive directly with mtx and try again. > > btape -c bacula-sd.conf /dev/rmt/0cbn > Tape block granularity is 1024 bytes. > btape: butil.c:286 Using device: "/dev/rmt/0cbn" for writing. > 10-Jul 14:51 btape: 3301 Issuing autochanger "loaded? drive 0" command. > 10-Jul 14:51 btape: 3302 Autochanger "loaded? drive 0", result is Slot 1. > 10-Jul 14:51 btape: 3301 Issuing autochanger "loaded? drive 0" command. > 10-Jul 14:51 btape: 3302 Autochanger "loaded? drive 0", result is Slot 1. > btape: btape.c:368 open device "Ultrium-TD3" (/dev/rmt/0cbn): OK > > This seems to work, so I run the "test" command in btape > > btape: btape.c:1348 Now forward spacing 1 more file. > We should be in file 5.

I suppose that's because btape is really only a very simple test tool and the autochanger usage is not implemented in basic tape drive testing. Nothing to worry about, that only ensures you know how to operate your autochanger even when it doesn't work automatically ;-) Arno > Thanks, > Shon > > > ------------------------------------------------------------------------ > > ------------------------------------------------------------------------- > This SF.net email is sponsored by DB2 Express > Download DB2 Express C - the FREE version of DB2 express and take > control of your XML.
