3 Getting Started with nPartitions HP Superdome 2 with sx3000 processors uses c-Class technology for the architecture of the system. The management of Superdome 2 is done by an Onboard Administrator (OA) with enhanced firmware. This Onboard Administrator has partitioning capabilities, both for hard partitions (nPartition) and for virtual partitions (vPar) . You can manage the nPartitions and virtual partitions through the OA without the need to install software on any disk. Partitions can also be managed from the OS's in the partitions (nPartition or vPar). The same set of commands as in legacy servers can be used for partition management on HP Superdome 2 servers. This chapter addresses the following topics: • "Administration Tool for nPartitions" • "nPartition Resources" • "nPartition Properties" • "Blade Resource Attributes" • "Operating System Specific Default Values for nPartition Attributes" • "Partition State and RunStates" • "Partition Specifications (parspec)" Administration Tool for nPartitions The administration tool for nPartitions is the OA, which provides a graphical user interface and a command-line interface.

Administration Tool for nPartitions
The administration tool for nPartitions is the OA, which provides a graphical user interface and
a command-line interface. This section discusses the following topics:

“Commands for Configuring nPartitions”
Onboard Partition Manager
The Onboard Partition Manager is a set of tools integrated with the HP Superdome 2 Onboard
Administrator. The tools in the Onboard Partition Manager allow you to configure both nPartitions
and virtual partitions. These tools replace the legacy tools for partition configuration (ParMgr
for nPartitions and vparmgr for virtual partitions). The Onboard Partition Manager tools provide
many enhancements over the previous tools The OA GUI can be launched either directly from
the OA or from an operating system instance via the HP System Management Homepage (SMH).
Commands for Configuring nPartitions
You can use the nPartition commands within an instance of HP-UX to create, modify, monitor,
and remove nPartitions (with the exception of
parperm
, which is available only from the OA).
Table 3-1
describes the nPartition configuration commands.
NOTE:
To execute partition commands from the operating system,
root
access is required.
