SUMMARY: SDLT320 tape full

It seems that it's a known problem. Here is Jason's answer:
-----------------
I had that blocksize error but the entry in st.conf fixed that.  I also had
the tapes reading as full when they weren't - and I fixed it by doing four
different things (maybe all three were needed, or just one of them, I'm not
sure but I don't get that error anymore).

I have a Quantum M1800 tape library, with 4 SDLT320 drives.

1) I had all four drives on one SCSI3 interface, which is too slow to push
data to all 4 drives.  So, I ordered 2 X6758A cards (dual channel SCSI3, and
gave each drive its own channel.)
2) I may have actually had a bad drive, and got that replaced.
3) the st.conf entry you note below.
4) Had Quantum send someone to upgrade the firmware on each drive

It's important to note that even though the tape is marked full and isn't, I
wasn't able to mark it "appendable" in Solstice Backup and have it write to
the tape again.  It just wouldn't.

I also had problems recovering from those sorts of tapes.  I ended up
relabelling them all and then they worked normally.

We're also running EBS 7.1.1 instead of 7.0 - on a Solaris 9 machine - a
SunFire v240.

Now it's been running for a few months now and the only problem is every now
and then we get unmount timeouts, but they fix themselves and have never
caused a backup or recover to fail (it just needs to wait until it times
out, then it works fine.)
----------------

Right now I upgraded to EBS 7.1 with patch 116826-2 (Build 277). I also
patched with the sd/st patch 113277-21.

I will post an updated if it solves my issue.

Thanks
