Nonzero allocation class examples with an asterisk indicate duplicate device names.
For one of the DSSI buses, the unit numbers need to be reprogrammed to avoid this error.

DSSI Device
Parameters Figure 6–8 shows sample DSSI buses and drive IDs for a sample
expanded DEC 4000 AXP system.
Following Figure 6–8 is an example in which the allocation class
will be set to 1, the devices for Bus A (in the DEC 4000 AXP) will
be assigned new unit numbers (to avoid the problem of duplicate
unit numbers), and the system disk will be assigned a new node
name.
