new at 11i original

Several system administration commands are provided with HP-UX 11i for creating and

Additionally, the existing commands shutdown, reboot, and setboot have been
modified to support nPartition platforms.
New Commands
Below are brief descriptions of the seven new commands used to manage an nPartition
server complex:
Modified Commands
The commands shutdown and reboot have been modified for systems that support hard
partitions. Two new options, -R and -H, have been added to both these commands.
The -R option is used to shut down the system to a “ready to reconfig” state and reboot
automatically. The -R -H option is used to shut down the system to a “ready to reconfig”
state but without rebooting. A partition must be put into the “ready to reconfig” state
before its newly assigned cells can be activated. (A normal reboot will not activate newly
assigned cells.) The “ready to config” state is also necessary to complete the removal of
active cells that have been unassigned from the partition. The commands’ default
behaviors, or the behaviors of all the other existing options, remain unchanged.
The interpretation of Autoboot and Autosearch in the command setboot has changed
for systems that support hard partitions. The firmware interprets the bits in
combination and not individually as done before.
In order to approximate the traditional behavior of setboot, the user input for the
Autoboot and Autosearch flags is internally mapped to the right combination to achieve
the desired behavior. This mapping should be transparent to the user of setboot, but it
