Hi,
I'm having a problem with an HP Surestore 24x6i DDS3 tape changer
on a FreeBSD 4.0 box.
I can talk to the changer ok, but the tape drive is giving me
trouble. I can get the status from the drive, advance, erase, rewind
a tape and so on using mt, but attempts to read or write to a tape
using tar or dd give me errors like this:
#tar cf - build | dd of=/dev/rsa0 bs=1024
dd: /dev/rsa0: Input/output error
2+0 records in
1+0 records out
1024 bytes transferred in 0.016840 secs (60808 bytes/sec)
..with the following errors appearing in the kernel message log and
on the console:
(sa0:ahc0:0:4:0): WRITE(06). CDB: a 0 0 2 0 0
(sa0:ahc0:0:4:0): ABORTED COMMAND asc:4b,0
(sa0:ahc0:0:4:0): Data phase error
I've tried it with different block sizes, I've checked the dip
switches, I've cleaned the drive, I've tried new tapes.. I've
tried everything I could think of. The tape drive appears to
work fine on an NT system.
I can't find any mention of this problem in mailing lists or
search engines. I'm about to start bashing my head against a wall :(
Possibly pertinent info:
uname -a:

Any advice would be greatly appreciated.

P.S. I've been using FreeBSD for over 4 years now, yet somehow
this is the first time I've posted to freebsd-questions.. Is this
a ringing endorsement for the quality of the docs in general? :)
