Quantum DLT4000 on AIX 4.3.3...

[Steve Coutts]

New to AIX, not so new to unix...

Have a Quantum DLT-4000 on a F80 running AIX 4.3.3 and I can't seem to make
this darn thing work consistently. I run a script which does a mksysb, then
a pax backup of another filesystem. The mksysb works fine - everytime! The
pax FAILS - everytime. See typical errors below.

pax: write : A remote host did not respond within the timeout period.
pax: 0511-613 A write error has occurred.
OR
pax: write : There is an input or output error.
pax: 0511-613 A write error has occurred.

The filesystem I'm backing up is on an IBM RAID controller. The DLT is on a
different SCSI controller.

What I've done:
- Set block_size and var_block_size to 0 as per Quantum FAQs
- tried different block sizes ranging from 1K to 256K (all fail)
- tried substituting tar for pax and even backup instead - no luck
- updated firmware to latest version from Quantum
- moved DLT to really old RS/6000 running 4.3.2 - it worked fine
everytime

I'm starting to lose it on this one, any help would be greatly appreciated.

Thanks.

Did you try to make a tar? or a savevg?
or dd if=/fs of=/dev/rmt0 bs=4kb

The dd thing didn't really do what I expected.

But I did a little bit more experimenting last night. The DLT works fine on
every one of my filesystems, except /rd01, which is a large RAID5 volume
created on an IBM PCI 2-Channel Ultra2 SCSI RAID adapter.

I'm running out of ideas.
