Well... after having discovered mt rdhpos/sethpos :), and mounted
the drive into a new external case (the old ones PSU died), i now have
some more data:
1. exactly the same happens when i use mt sethpos instead of the
camcontrol script: the 1st tar returns `tar: rec 0: Blocksize = 12 records',
(ok so maybe the position i gave is a few blocks off), the next goes
hanging like mentioned above. And if i then look at the console there
is this:
Apr 27 19:00:22 saturn /kernel: (sa0:ncr0:0:5:0): WRITE FILEMARKS. CDB: 10 0 0 0 0 0

Apr 27 19:02:51 saturn /kernel: (sa0:ncr0:0:5:0): Command sequence error
Huh!?? Why on earth is it trying to write filemarks?? Good that the
tape was write protected...
2. reading the tape from beginning (repeated tar tfvR /dev/nrst0 until
the wanted position is reached) works ok i.e. i then can read past the
failing spot without problems. (except that doing it this way takes
looong...) so i presume something in the internal state of the nrst (sa)
driver is causing the problem... (the tape drive is most likely
innocent, see below.)
3. mt bl(ocksize) doesn't work. regardless what blocksize i give i get:
Apr 27 16:00:47 saturn /kernel: (sa0:ncr0:0:5:0): MODE SELECT(06). CDB: 15 0 0 0 c 0
Apr 27 16:00:47 saturn /kernel: (sa0:ncr0:0:5:0): ILLEGAL REQUEST asc:26,0
Apr 27 16:00:47 saturn /kernel: (sa0:ncr0:0:5:0): Invalid field in parameter list sks:8f,4
(should the requested blocksize appear in the CDB? it is always
15 0 0 0 c 0...) the default blocksize is OK (tape is streaming)
so this doesn't worry me too much, but i thought i'll mention it anyway.
(on a related note, i cant get camcontrol defects to work on any of my
4 disk drives, i only get this:
Apr 27 15:55:48 saturn /kernel: (probe0:ncr0:0:0:0): COMMAND FAILED (6 ff) @0xf07a1400.
dmesg below.)
4. on one reboot i got this:
Apr 27 15:55:48 saturn /kernel: Waiting 5 seconds for SCSI devices to settle
Apr 27 15:55:48 saturn /kernel: ncr0: restart (scsi reset).

and then it goes on listing the SCSI devices as usual. should i worry?
5. back to the tape, booting a 2.2.8-stable kernel: the tape is not
streaming and regardless what blocksize i set it to it stays that way
(always start/stop behavior). i did not try my positioning script.
6. booting a 2.1-stable kernel: everything works! the tape is
streaming, i can position it (using my old version of the script thats
doing scsi -f), and then i can read from there on without problems.
well, there is one minor nit: i first have to read a few blocks off
/dev/nrst0 or else it will rewind before starting to read after the
positioning command...
Here is the latest dmesg (boot -v, 3.1-stable):
