I think this has probably been asked in one form or another (Gee, we
really need to re-activate the Linux-SCSI FAQ/HOWTO), but I have a
specific need.
I have a BusLogic BT-958 for the disks with all my *main* partitions
(/ /usr /var /usr/local /home /cdrom, etc.), and I have an aha152x for
my ZIP drive. (Since the ZIP uses that 25pin pseudo-SCSI, I didn't
want to *infect* my *real* SCSI chain with that. :))
The aha152x support is modularized, so if I don't really want it, or if
the ZIP isn't connected, I can remove the modprobe in my /etc/rc.d/rc.modules
and it won't load. I was wondering, then, if I can do the following
with the machine *ON*:
# rmmod aha152x
<power down ZIP>
<unplug ZIP from aha152x>
<take ZIP to another machine>
<do stuff>
<bring ZIP back to Linux PC>
<reconnect ZIP to aha152x>
<power up ZIP>
# modprobe aha152x
If it's the only thing on the bus, it should be fine, no?
If this works, then could I also add/remove other devices the same way,
so long as nothing on the chain was mounted?
