Archive tape problem

Post by Michael Eng » Mon, 09 Jan 1995 22:08:35

Hello all,

I have a somewhat weird problem with my tape drive, an Archie 2150S.

My configuration:
386DX40 16 MB RAM
Adaptec 1542CF
Quantum LPS540S on SCSI ID 0
Quantum LPS425S on SCSI ID 1
Archie tape on SCSI ID 4

Whenever I try to access the tape (via tar, cpio or dd), the tape rewinds
for a few seconds, then I get a SCSI timeout error foer targets 0 and 1
(ie the disk drives). When the tape starts running, everything seems to work
OK. After the tape operation is completed, I get lots of messages complaining
about unexpected interrupts.

This did not happen with kernel 1.08, but with all later kernel versions
I was using : 1.1.35, 1.1.59 and 1.1.73. Still worse, 1.1.35 and 1.1.59
got a kernel panic with the message "can't find free mailbox for aha1542"
(or similar).

I assume the SCSI bus is not released while the tape is rewinding, so the disks
cannot be synced.
Additionally, from time to time I get lots of messages "inode xyz already
cleared." which sure as hell make fsck fail on the next reboot.

So, what am I doing wrong ? The tape works fine with my Sun-3/60, so it can't
be the drive.

Any help is appreciated  !
Thanks a lot,


1. Formatting tapes with an Archive 5945 tape drive

I have an Archive 5945 (QIC-24) tape drive with an Emulex MT-02
controller hooked up to my Seagate ST-01 SCSI host adapter in my PC.
(Not very modern equipment huh? ;-)

I'd like to format some QIC-24 tapes so I can make some backups
under Linux. But, AFAIK, noone has created anything that will format
tapes under Linux.

Does anyone know of any DOS software that will do the format with my
equipment??? Where can I get it???
