[clug] ch0 missing

Here at work we have a fibre tape library (connected to a switch) which
I use to backup data with Amanda and tar.
One annoyance is that /dev/ch0 doesn't seem to be created on boot, which
means that I have to scan the scsi bus to find out the sg device and
update files with the new device if we lose power.
I have /dev/st0 and /dev/nst0, just no /dev/ch0. I would have thought
this device would be created by udev, but maybe I'm wrong?
I can't seem to find any information on how I should create this device.
For now I have a symlink but it's a little clunkalicious. Any ideas?
