basic - how to reset ?

[George Locke-2]

Hi,

I'm trying to track down a problem i'm having talking to this archaic
hardware, and among the tasks is to make sure my scsi controller is
working.  (the archaic hardware is a CAMAC crate, which in this case
communicates to the computer on the scsi bus.)

I'm running current fedora on a brand new dell tower, using an adaptec
aha-2940u pci card.

I would be happy to hear RTFM replies if they are accompanied by a link to
the manual!  haven't found a basic resource explaining the aic7xxx routines,
etc.

So all i want to do is write a little C++ (or other) program that i can run
to just reset the scsi bus to see if the driver is working properly.

thanks!

Hi again,

So i'm going through the aic7xxx header files and I find this routine:

ahc_reset <http://www.gelato.unsw.edu.au/lxr/ident?i=ahc_reset>(struct
ahc_softc <http://www.gelato.unsw.edu.au/lxr/ident?i=ahc_softc> *ahc,
int reinit <http://www.gelato.unsw.edu.au/lxr/ident?i=reinit>)

(see
http://www.gelato.unsw.edu.au/lxr/source/drivers/scsi/aic7xxx/aic7xxx_core.c#L3992)

this routine seems to be the function i'm looking for, but it takes a
ahc_softc as an argument, which is a struct defined in aic7xxx.h (
http://www.gelato.unsw.edu.au/lxr/source/drivers/scsi/aic7xxx/aic7xxx.h#L915)

this struct is huge and contains about a gagillion data-members.  There has
to be some way that I can create one in some automated way, right?  or do i
have to fill in each blank myself?

thanks,
George
