I have Bacula 5.0.3 on FreeBSD 8.2 backing up to an IBM Ultrium ULT3580 tape
drive, using 400~800GB tapes, connected to an Adaptec 39320LPE Ultra320 SCSI
adapter. I'm using SQLite and have 4GB of RAM.
I used to have a Quantum DLTV4 tape drive, but I was getting SCSI errors
every few weeks, so I switched to the Ultrium.
I've used 3 other tapes in this drive with no issues. This tape fails:

Please use the "label" command to create a new Volume for:

I've tried migrating the jobs from the tape, but I get:

I was able to write multi-tape btape fill to this tape with no errors. I
haven't completed the read test, yet.
Here's a sample error from my old Quantum DLTV4 drive, since I feel like
these might be connected.
Dec 14 03:34:35 bsd kernel: (sa0:ahd0:0:5:0): SCSI status: Check Condition
Dec 14 03:34:35 bsd kernel: (sa0:ahd0:0:5:0): SCSI sense: UNIT ATTENTION

Dec 14 05:34:46 bsd kernel: ahd0: Recovery Initiated - Card was not paused
Other things I've done:
* Replaced the SCSI adapter
* Replaced the SCSI cable and terminator
Here's the current SCSI adapter info
# dmesg
ahd0: <Adaptec 39320LPE Ultra320 SCSI adapter> port
0xe400-0xe4ff,0xe800-0xe8ff mem 0xfbd7e000-0xfbd7ffff irq 16 at device 4.0
on pci4
ahd0: [ITHREAD]
aic7902: Ultra320 Wide Channel A, SCSI Id=7, PCI-X 101-133MHz, 512 SCBs
Only other thing I haven't done is move to MySQL since my bacula.db is about
3.6 GB holding ~18M files in 332 jobs:
select sum(JobFiles) from job;
+---------------+
| sum(JobFiles) |
+---------------+
| 18685071 |
+---------------+
Enter SQL query: select count(*) from job;
+----------+
| count(*) |
+----------+
| 332 |
+----------+
I have no idea where else to look. Any help is appreciated!
