The "etch" system is setup to handle discovery order for cd's and
network interfaces while keeping device names the same.  

The scsi rules are not set up to stabilize the assignments in a similar 
manner, but should be easy to fix.

Look in /etc/udev/ and /etc/udev/rules.d 

- tweak /etc/udev/persistent.rules
to work the same as the pair: /etc/udev/persistent-net-generator.rules
and /etc/udev/rules.d/z25_persistent-net.rules

I.E: Turn /etc/udev/persistent.rules into a "generator" of
/etc/udev/rules.d/z20_persistent_scsi.rules
and
rename the /etc/udev/rules.d/z20_persistent.rules link into
/etc/udev/rules.d/z23_persistent.rules so that it will be
run if the corresponding "generator" has not been run.

Contact me off-list if you have trouble with this local solution.

The above is a "local" solution - not approved by Debian.
I am not guessing here if their solution will be the same or not.
