If the SCM dies the only thing that is hindered is adding new users/changing passwords and the creation of new volumes. It is trivially to select one of the other server as the new SCM. All required data is already replicated, you just need to tell every server who the new SCM is ( echo 'newscmhostname' > /vice/db/scm ; /etc/rc.d/init.d/update.init restart ) Regular Coda clients accessing the system are not disturbed at all.
