Re: more with Amanda and Sun L9

I've had another go at this today by shifting the entire Amanda host
setup to a different machine (Sun Ultra 2) and recompiling mtx and
amanda from source. I'm using the same sort of Sbus Qlogic
differential SCSI card to communicate with the L9 array that I had in
the previous host system.
After figuring our the right config for the 'sgen' driver, I changed
the amanda.conf file to show the device name for the changer (it's
been detected as /dev/scsi/sequential/c1t1d0).
I have all the directories that Amanda needs created and chowned to be
owned by amanda with group 'sys' and I also changed all the /dev/rmt
nodes along with /dev/scsi/sequential/c1t1d0 to be owned by amanda
with group 'sys'.
However when I rum 'amcheck' I still get the:
Changer problem: no slots available
error message that occured with the previous host system. Running
'amtape ORBnet update' produces the same thing.
If I replace 'tapelist' with a blank file, same result.
I'm also starting to think the problem is the array itself but I am
sure others are using L9's with Amanda without any problems, even
connected to a Sun box for the host.
Can anyone think of anything else I should be checking?
Running 'mtx -f /dev/scsi/sequential/c1t1d0 inquiry' reports the DLT
drive type, etc. as expected.
Just a possible note on this.
When I configured my AIT5 library, I configured the tape drive with
st.conf and the library with sgen.conf. I ended up getting the tape as
/dev/rmt/1 and the library as /dev/scsi/changer/something. In the
process of setting it up, I did everything one step at a time. I first
just played with the front panel of the library to load a tape and mt
and ufsdump to do things with the tape. Then I installed mtx and
configured it and spent some time playing with that to see that I could
move tapes around and load them and unload them. Finally, I configured
chg-zd-mtx and amanda to use the tape drive and changer. Then I played a
bit with amtape and amlabel to see that I could set the current slot,
check the tape in the current slot, label it and so on. Only after that
did I set up a tape rotation and launch amdump. That process kept it
from being too complicated.
The question I would have on your setup is whether your changer presents
itself as 2 different devices and needs to be set up this way (using
both st.conf and sgen.conf). I never had to mess with ownership of
anything in /dev.
