An Overview of nPartition Boot and Reset
Types of Booting and Resetting for nPartitions
HP System Partitions Guide: Administration for nPartitions, rev 5.1 164
After you assign a cell to an nPartition, or remove an active cell from
an nPartition, you can perform a reboot for reconfig of the nPartition
to complete the cell addition or removal.
If an nPartition is configured to boot HP-UX automatically, it can do
so immediately following a reboot for reconfig.
• Ready for Reconfig State
A reboot to the ready for reconfig state shuts down HP-UX, resets
all cells assigned to the nPartition, performs any nPartition
reconfigurations, and keeps all cells at a boot-is-blocked (BIB) state,
thus making the nPartition and all of its cells inactive.
When an nPartition is at the ready for reconfig state you can add or
remove cells from the nPartition from a remote nPartition within the
server complex.
To put an nPartition into the ready for reconfig state use the
shutdown -R -H command, the BCH interface’s RECONFIGRESET
command, or the service processor Command menu’s RR command.
To make an nPartition boot past ready for reconfig, use the service
processor Command menu’s BO command. The BO command makes
the nPartition active by allowing its cells to boot past BIB,
rendezvous, and boot to the BCH interface (and, if configured,
automatically boot HP-UX).
• TOC: Transfer-of-Control Reset
When you initiate a transfer-of-control reset, the service
processor immediately performs a TOC reset of the specified
nPartition, which resets the nPartition and allows a crash dump to
be saved.
If crash dump is configured for HP-UX on an nPartition, then when
you TOC the nPartition while it is running HP-UX, the nPartition
performs a crash dump and lets you select the type of dump.
To perform a TOC reset, use the service processor Command menu’s
TC command.
HP nPartition systems do not have TOC buttons on the server
cabinet hardware.
