Hi, I'm having trouble with a MSL6000 tape cabine.
I would like to ask to help, but I don't known which is the appropiate list. So, I'm asking you about the problem, and I'll be appreciate any pointer. My problem: I have a -old (debian sarge)- bacula system with a MSL6000 attached with fiber channel. This system was working until 2 weeks ago. The logs are (a lot of times): Bacula: 28-Oct 01:47 backup-sd: BackupCatalog.2009-10-27_20.00.22 Fatal error: 3992 Bad autochanger "load slot 5, drive 0": ERR=Child died from signal 15: Termination. 28-Oct 01:47 backup-fd: BackupCatalog.2009-10-27_20.00.22 Fatal error: job.c:1617 Bad response to Append Data command.
