[Bacula-users] FreeBSD and HP Surestore 40x6e

[Markus B. <bu...@hi...>]

Hi,

I have problems getting my HP SureStore 40x6e to work with Bacula 1.30a on=
=20
=46reeBSD 5.1-BETA (had the same problems on 4.8-STABLE before upgrading to=
 5.1=20
=2DBETA):

Device {
   Name =3D "HP SureStore 40x6e"
   Media Type =3D DDS-4
   AutoChanger =3D Yes
   Archive Device =3D /dev/nsa0
   Changer Device =3D /dev/pass3
   Changer Command =3D "/usr/local/sbin/mtx-changer %c %o %S %a"
   LabelMedia =3D no               # lets Bacula label unlabeled media
   AutomaticMount =3D yes               # when device opened, read it
   AlwaysOpen =3D yes
   RemovableMedia =3D yes

   # needed for FreeBSD
   BSF At EOM =3D yes
   Hardware End of Medium =3D No
}

A "test" with btape yields the following:

brueffer@ramses:/usr/local/etc # btape -c bacula-sd.conf /dev/nsa0
Tape block granularity is 1024 bytes.
btape: butil.c:149 Using device: /dev/nsa0 for writing.
*test


=3D=3D=3D Append files test =3D=3D=3D

This test is essential to Bacula.

I'm going to write one record  in file 0,
                   two records in file 1,
             and three records in file 2

btape: btape.c:387 Rewound /dev/nsa0
btape: btape.c:857 Wrote one record of 64412 bytes.
btape: btape.c:859 Wrote block to device.
btape: btape.c:410 Wrote EOF to /dev/nsa0
btape: btape.c:857 Wrote one record of 64412 bytes.
btape: btape.c:859 Wrote block to device.
btape: btape.c:857 Wrote one record of 64412 bytes.
btape: btape.c:859 Wrote block to device.
btape: btape.c:410 Wrote EOF to /dev/nsa0
btape: btape.c:857 Wrote one record of 64412 bytes.
btape: btape.c:859 Wrote block to device.
btape: btape.c:857 Wrote one record of 64412 bytes.
btape: btape.c:859 Wrote block to device.
btape: btape.c:857 Wrote one record of 64412 bytes.
btape: btape.c:859 Wrote block to device.
btape: btape.c:410 Wrote EOF to /dev/nsa0
btape: btape.c:387 Rewound /dev/nsa0
btape: btape.c:695 Now moving to end of media.
btape: btape.c:427 Moved to end of media
We should be in file 3. I am at file 3. This is correct!

Now the important part, I am going to attempt to append to the tape.

btape: btape.c:857 Wrote one record of 64412 bytes.
btape: btape.c:859 Wrote block to device.
btape: btape.c:410 Wrote EOF to /dev/nsa0
btape: btape.c:387 Rewound /dev/nsa0
Done appending, there should be no I/O errors

Doing Bacula scan of blocks:
1 block of 64448 bytes in file 1
End of File mark.
Total files=3D1, blocks=3D1, bytes =3D 64448
End scanning the tape.
We should be in file 4. I am at file 1. This is NOT correct!!!!

The above Bacula scan should have output identical to what follows.
Please double check it ...
=3D=3D=3D Sample correct output =3D=3D=3D
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=3D4, blocks=3D7, bytes =3D 451136
=3D=3D=3D End sample correct output =3D=3D=3D

If the above scan output is not identical to the
sample output, you MUST correct the problem
or Bacula will not be able to write multiple Jobs to
the tape.


=3D=3D=3D End Append files test =3D=3D=3D

The tape is reportet by FreeBSD as follows:

sa0 at ahc1 bus 0 target 3 lun 0
sa0: <HP C5713A H910> Removable Sequential Access SCSI-2 device
sa0: 40.000MB/s transfers (20.000MHz, offset 32, 16bit)
ch0 at ahc1 bus 0 target 3 lun 1
ch0: <HP C5713A H910> Removable Changer SCSI-2 device
ch0: 40.000MB/s transfers (20.000MHz, offset 32, 16bit)
ch0: 6 slots, 1 drive, 0 pickers, 0 portals

and:

brueffer@ramses:/usr/local/etc # camcontrol devlist
<PLEXTOR CD-R   PX-R412C 1.07>     at scbus0 target 5 lun 0 (cd0,pass0)
<IBM DDYS-T36950M SC4D>            at scbus1 target 0 lun 0 (pass1,da0)
<HP C5713A H910>                   at scbus1 target 3 lun 0 (sa0,pass2)
<HP C5713A H910>                   at scbus1 target 3 lun 1 (ch0,pass3)

Did I miss something?

Best Regards,

Markus
