okay, i'll try to help as far as i can with my nonexistant udev rules.
the catchall is there because you *don't* know which scsi disk it is,
wether it is sda, sdb or whatever. 
however, the DISK does have a unique serial number (even raid slices do)
or at least a WWN.
so you basically need to find out which unique number your unique disk
has (by using /sbin/scsi_id -p 0x83 -g -u -s /block/sda), tell that the
udev system and let it create a symlink you name whatever you like. this
way, every node get's a symlink with the same name for the same disk,
whatever the state of it's device enumeration is. 
oh, any udev gurus.. i suppose udev uses page 0x83 rather then 0x80, is
that correct?
