AlphaServer 1000A with TLZ09 DAT

[Rui Barreiros]

Hi there,

I recently acquired an alphaserver 1000A 5/400 with a TLZ09 DAT tape,
been having alot of trouble to have a decent linux distro working on it
due to the scsi driver, and also tried some bsd distros but with
problems too regarding to the eisa bus...

Well, finally, AlphaCore works very well, (as always, redhat/fedora
never let me down) but i have some strange quirks working with the tape,
whatever command i issue (except an mt status) it get's offlined, here
is the relevant part of messages log:

Jun 26 23:33:03 gimli kernel: scsi0 (4:0): rejecting I/O to offline

this happened when i was doing a mt erase on the tape, but whatever i do
(erase, rewind, forward, a simple tar) i get the same errors above, and
the tape get's offline, since i don't know how to get here back online,
i have to reboot the machine.

Currently using stock alphacore 1.0 with kernel 2.6.11-1-1180

Tape is a TLZ09 and SCSI is a Qlogic 1040

Does anyone know how can i solve this ? or do i have to sit tight and
wait for a kernel patch that solves this ??

i don't mind to be the testbed for any issue as along as this can be
solved :)

Regards,
