5-6 Getting Started with Logical Partitions
5.3
Halting All Partitions to Reconfigure
You may wish to change the allocations set with the lp_* environment
variables, in effect reconfiguring your partitions. Shut down the
operating system in each partition, reset the system, change the
settings as desired, reset the system, and issue an lpinit command.
Example 5–3 All Consoles: Shut Down Operating System
# /usr/bin/shutdown –h +5 “Shutting down to reconfigure partitions”
