Types of Booting and Resetting
for nPartitions
All standard boot and reboot methods are supported for HP nPartition
servers, though some boot and reset procedures differ slightly or use
different tools than on other HP servers.
HP’s nPartition servers also provide two special types of reboot and reset
for managing nPartitions: performing a reboot for reconfig, and resetting
an nPartition to a ready for reconfig state.
• Reboot for Reconfig
After you assign a cell to an nPartition, or remove an active cell from
a partition, you can perform a reboot for reconfig of the partition to
complete the cell addition or removal.
Performing a reboot for reconfig resets all cells in an nPartition,
completes any pending partition changes (adding or removing cells),
and reboots the partition to its Boot Console Handler interface.
If a partition is configured to boot HP-UX automatically, it can do so
immediately following a reboot for reconfig.
The shutdown -R command performs a reboot for reconfig of the local
partition.
• Ready for Reconfig State
When you reset an nPartition to a ready for reconfig state, all cells in
the partition are reset and any partition changes take place, but the
partition and all its cells remain inactive at boot-is-blocked (BIB).
Resetting an nPartition to ready for reconfig prevents the partition
from automatically booting to its BCH interface or HP-UX.
To make a partition boot past ready for reconfig, use the service
processor Command menu’s BO command. The BO command makes
the partition active by allowing its cells to boot past BIB, rendezvous,
and boot to the BCH interface (and, if configured, automatically boot
HP-UX).
When a partition is at a ready for reconfig state you can add or
remove cells from the partition from a different, remote partition
within the server complex.
