Booting HP-UX on vPars
This section provides a procedure for loading and booting HP-UX on a
Virtual Partition that is running in an nPartition on an HP Superdome
server.
As part of the vPar boot process, you will boot the /stand/vpmon vPars
monitor from the nPartition BCH interface instead of booting the
/stand/vmunix HP-UX kernel.
From the vPars monitor (the MON> prompt) running on an nPartition, you
can load one or more Virtual Partitions. Each vPar then can boot a single
instance of the HP-UX kernel.
Before performing this procedure, review the following list for an
overview of situations you may encounter when loading and booting
Virtual Partitions on an nPartition server.
• If one or more vPars already has loaded/booted HP-UX on the
nPartition, you can load/boot additional vPars from HP-UX running
on one of the existing vPars.
In this situation, you can issue the vparboot command to load other
vPars; see the vparboot (1M) manpage for details.
However, you can only load vPars that are defined in the currently
active vPars configuration database, which typically is the
/stand/vpdb file on the same boot device where /stand/vpmon was
booted.
• If HP-UX is booted in non-vPars mode on an nPartition, you must
shut down HP-UX on the nPartition and from the nPartition’s BCH
interface boot the /stand/vpmon vPars monitor before loading any
vPars.
These above situations also are addressed in the following procedure.
vPar Management: Booting HP-UX 11i on vPars in an nPartition
This procedure describes how to boot HP-UX on one or more Virtual
Partitions in a single nPartition on an HP Superdome server.
Also refer to the chapters An Overview of nPartition Boot and Reset on
page 161 and Booting and Resetting nPartitions on page 197 for details
on booting nPartitions.
Step 1. Login to the HP Superdome service processor (GSP) for the server where
the vPars will be booted.
