Dynamic Reconfiguration User's Guide 2.5.1

2.3.2 DR configuration and OBP (Open Boot PROM)

All listed OBP environment variables in this section are provided specifically for DR. When you change an OBP environment variable by the eeprom(1M) command, the system must be rebooted to make the change effective. However, if DR attaches the system board listed on an OBP environment variable, the change becomes effective without reboot.

OBP environment variables exist on each partition. The setting for one partition does not influence other partition.
