An Overview of nPartition Boot and Reset
Types of Booting and Resetting for nPartitions
HP System Partitions Guide: Administration for nPartitions, rev 5.1 163
• Reset
A reset resets the nPartition immediately. Only the nPartition’s
active cells are reset.
You can reset an nPartition using the BCH interface’s REBOOT
command or the service processor Command menu’s RS command.
The RS command does not check whether the specified nPartition is
in use or running HP-UX—be certain to correctly specify the
nPartition.
• Boot an nPartition from the Service Processor (GSP or MP)
A boot initiated from the service processor boots an inactive
nPartition past the ready for reconfig state.
The nPartition’s cells proceed past boot-is-blocked (BIB), rendezvous,
and the nPartition boots to the BCH interface.
To boot an inactive nPartition, use the service processor Command
menu’s BO command.
• Boot HP-UX from the BCH Interface
To boot HP-UX on an nPartition, use the BCH interface’s BOOT
command and specify the device path from which the program
loaders and HP-UX kernel .
The BCH interface’s BOOT command loads and boots HP-UX on an
nPartition. This command also can be used to load and interact with
the Initial System Loader (ISL) interface. Likewise on Superdome
servers the Virtual Partitions monitor (MON> prompt) is loaded
following the BOOT command.
• Reboot for Reconfig
A reboot for reconfig shuts down HP-UX, resets all cells assigned
to the nPartition, performs any nPartition reconfigurations, and
boots the nPartition back to the BCH interface.
To perform a reboot for reconfig of the local nPartition, use the
shutdown -R command.
All cells—including any inactive cells and all newly added or deleted
cells—reboot and are reconfigured. All cells with a “y”
use-on-next-boot setting participate in partition rendezvous and
synchronize to boot as a single nPartition.
