Nonzero allocation class examples with an asterisk indicate duplicate device names.
For one of the DSSI busses, the unit numbers need to be reprogrammed to avoid this error.
You should configure your system to have unique unit numbers even if
you have a standalone system using an allocation class of zero. That
practice will avoid problems with duplicate device names if you later
decide to form a cluster.
