Re: [Bacula-users] FreeBSD and HP Surestore 40x6e

[Kern S. <ke...@si...>]

Hello Markus,

I've been working with another user for several
weeks to get Bacula working on a FreeBSD system, and
I have not yet succeeded.  Previously I did succeed
in making Bacula work on a FreeBSD system (in Brazil
if I remember correctly) which is the reason it
is quoted in the manual.

I am using the identical autochanger tape drive
here with my Linux system, and it functions flawlessly.

In addition, a we tried running the test command on FreeBSD
yesterday, and it works correctly. Even with that working, 
we are not able to do successful restores on FreeBSD in all 
cases.

The output you are getting is definitely not correct, but
it doesn't make much sense to me unless you haven't put
your drive into two eof mode.  You can do so by issuing the
following command:

   mt -f /dev/nsa0 seteotmodel 2

If it doesn't work after that, I am out of ideas.  You might
also check your system log to see if there are any
kernel error messages reported.

If it seems to work, please test *very* carefully save
and restore. 

Best regards,

Kern

PS: It is beginning to look like the only possibility to get
    everything working on FreeBSD is for me to set up
    a system here, but that means buying another SCSI
    card and several weeks worth of work.
