adaptec 2940u/uw dump card state ends

[Jesse Guardiani]

Howdy list,

I'm having trouble with a Sony AIT TSL-SA300C autochanger
attached to an adaptec 2940u/uw SCSI card and a Seagate AIT
tape drive. Hopefully someone can shed some light on my
problem.

The physical (as in cable) SCSI topology looks like the
following, with terminated devices marked by a (T):

(T)AIT Autochanger <-> 2940u/uw <-> Seagate AIT Tape(T)

I have termination manually turned off in the 2940u/uw's
software configuration utility. The Seagate AIT tape drive
is terminated via jumper (Term PWR is off, and SCSI Term
is ON, if I remember correctly). The Sony Autochanger is
terminated using a long yellow external wide SCSI ribbon
cable. The cable has a little black thing on the end that
I am ASS-U-MEing is a resistor pack for termination. The
Autochanger's PDF indicates that it is not capable of
active termination, which makes sense because it's external
and you can turn it off.

Admittedly, termination may be the issue. I'm relatively
new to SCSI, and I may not have gotten it right. In
particular, I don't have a clue what the TERM PWR jumpers
do on devices that also include a SCSI TERM jumper...

Here is the problem I'm having:

The first time I issue a `chio move drive 0 slot 0` command,
I get this:

So far, all further commands have been successfull.

Here's my uname:

Any suggestions?

Thanks!
