I'm assuming that your ltsn config lives in /usr/local/etc/ltsn?
Just making sure this is the same amanda.conf that amanda is using :)

Almost, it's all inside /usr/local/etc/amanda/ltsn

rawtapedev "/dev/null"  # the raw device to be used (ftape only)
^^^^^^^^^
The above item should be commented out.  Don't know if thats the cause
of the problem though.

I'll try it, but I don't think it's the issue.

changerdev      /dev/ch0    # Jukebox changer
Ahh, here be dragons^^^^

Substitute for /dev/ch0, whatever your dmesg (boot log) identifies the
changer mechanism as.  I'll insert the pieces from mine for an
example of what to look for.  Unforch, its for linux_x86 here, so the
actual device names are going to be different.

From my own dmesg:

ahc1 at pci0 dev 14 function 0 "Adaptec AHA-2940U2 U2" rev 0x00: irq 10
ahc1: aic7890/91: Ultra2 Wide Channel A, SCSI Id=7, 32/255 SCBs
scsibus1 at ahc1: 16 targets
(ahc1:A:1:0): refuses WIDE negotiation.  Using 8bit transfers
ahc1: target 1 using asynchronous transfers
ch0 at scsibus1 targ 1 lun 0: <ADIC, FastStor DLT, D118> SCSI2 8/changer removable
ahc1: target 3 synchronous at 10.0MHz, offset = 0xf
st0 at scsibus1 targ 3 lun 0: <BNCHMARK, DLT1, 3213> SCSI2 1/sequential removable
st0: density code 0x40, variable blocks, write-enabled

I'm running OpenBSD here, and it identifies changers in the ch driver, therefore my changer is /dev/ch0

The only problem now is that I had to reboot the machine last night, due to a routing issue, and now my tape drive is in some wierd state:

bash-2.05b# chio status
picker 0: <EXCEPT>
slot 0: <ACCESS,EXCEPT>
slot 1: <ACCESS,EXCEPT,FULL>
slot 2: <ACCESS,EXCEPT,FULL>
slot 3: <ACCESS,EXCEPT,FULL>
slot 4: <ACCESS,EXCEPT,FULL>
slot 5: <ACCESS,EXCEPT,FULL>
slot 6: <ACCESS,EXCEPT,FULL>
drive 0: <ACCESS,EXCEPT,FULL>

And I can't get it out of that. I think I need to power cycle the lot of it, which will have to wait until monday when I can get at the machinery... :(
