[NTLUG:Discuss] SCSI scanner question

[Stephen Klein]

Let's see if I can help on this one.

As usual when troubleshooting SCSI, check for proper termination at both
ends of the SCSI chain (the controller does this automatically if it is
at the end of the SCSI chain).

First do a "cat /proc/modules" and make sure the aic7xxx (I think that's
it) module is loaded.  If you don't see it, try loading it yourself by
typing "modprobe -av aic7xxx".  If the module is not already loaded, you
will see something like this:

yoursystemname:~# modprobe -av aic7xxx
/sbin/insmod -L /lib/modules/2.2.17/scsi/aic7xxx.o
yoursystemname:~#

Scanners are accessed with the SCSI Generic (sg) driver.  It can either
be compiled into the kernel, or compiled as a module.  Try doing
"modprobe -av sg" and see if it loads, then do a "cat /proc/scsi/scsi"
and see if it lists your scanner.

On this, you might try running ldconfig, at least that's what I'd have
to do on my system (Slackware 7.0).  I'm not sure about Red Hat.
