my second scsi bus dies if dump reaches the end of a tape and i abort the
dump. the ncr scsi driver now report errors for each scsi operation. i
an using an archive anaconda QIC-1305 tape drive and dump. (boot dmesg
output at end, with kernel config file)
i have SCSIDEBUG and superscsi in the kernel, so i can provide more data
as requested.
scsi chain:
sc200 card----nakamichi---archive---fujitsu 1GB harddrive
ncr 53c810 7 cdrom anaconda
changer qic tape
target: 7 0 4 6
luns: 0-6 none none
dump process:
DUMP: 49.01% done, finished in 0:10
DUMP: End of tape detected
DUMP: Closing /dev/rst0.2
DUMP: Change Volumes: Mount volume #2
DUMP: Is the new volume mounted and ready to go?: ("yes" or "no")
DUMP: Is the new volume mounted and ready to go?: ("yes" or "no")
DUMP: Do y
ou want to abort?: ("yes" or "no") DUMP: The ENTIRE dump is aborted.
so i did an "mt -f /dev/rst0 rewoffl" the tape was ejected.
resulting dmesg output:
ncr1:4: ERROR (80:140) (8-2a-0) (0/13) @ (544:900b0000).

then i tried to mount a cdrom: (mount -t cd9660 /dev/cd6c /mnt)
the mount failed: "cd9660: /dev/cd6c: Input/output error"

inserted a tape into the drive, which accepted the tape.
then did another "mt -f /dev/rst0 rewoffl"
producing this output:
ncr1:4: ERROR (80:140) (8-2a-0) (0/13) @ (544:900b0000).

the tape was ejected. the cdrom changer sounds as if it changed cdroms!
the archive anaconda tape drive chatters/buzzes as if it is resetting ??
the only other item on this scsi chain is a fujitsu 1GB drive. trying
to mount causes:

and in dmesg:
