Can someone that understands CAM explain what (more or less) one needs to
do to handle the possible arrival/departure of a device?
It appears that if I send a rescan cdb to rescan an already existing
device, and the device is still present, something gets really upset.
Specifically, if I know that a particular bus/target may have undergone a
status change, and I want CAM to work out whether it's still there and
talking, what do I have to do in the case where a) we have a periph
attached to the b/t, and b) where there isn't a periph attached to it?
Examples would also be welcome.
Regards,
Mike
