I would try these combinations:
2 2 0 1
2 2 1 0
2 2 1 1

There was, and might still be, I recall a command in RHEL 3 I think it
was but I don't see it in newer versions. Looking at one of my
Debian Sarge systems running on a 2.4 kernel there is a scsiadd -s
command to scan for new devices but I don't see a scsiadd command
on my newer systems.
