Re: [Bacula-users] readlabel and btape

Hi Jeremy,

Thanks for the reply. These are new tapes. When I try to do a ‘label barcodes’ on the new tapes I get errors so I’ve been manually wiping them with the following commands.

[root@scrappy ~]# mtx -f /dev/sg2 load 1 0
[root@monk bacula]# mt -f /dev/nst0 rewind
[root@monk bacula]# mt -f /dev/nst0 weof

Is there more I should be doing?

Thanks,
JJ

What I see in your output is a status:
BOT (beginning of tape), online (tape in drive and drive ready for action), IM_REP_EN (Immediate report mode, tape drive might cache write instructions)

And a readlabel output that says your tape does not have a bacula label written to it (hence the strange garbled output).

So then the question is: Is this tape giving you any problems? Has it ever been written by bacula before the test? If so: you might want to consider the tape damaged, maybe try a btape test if it does not contain any valuable data.

Kind regards,
Jeremy
