Thanks everyone for suggestions and ideas.
I'm actually looking for something that can be done from
within a driver without any manual intervention.
Hmmm... Since:
echo "scsi add-single-device 0 1 2 3" >/proc/scsi/scsi
appears to result in the following call:
scan_scsis(HBA_ptr, 1, channel, id, lun);
is it possible for a SCSI driver to just make this call directly?
Before I try it, does anyone know of any reasons why this
wouldn't work?
Thanks again,
