3 Getting started with nPartitions HP Superdome 2 with sx3000 processors uses c-Class technology for the architecture of the system. The HP Superdome 2 is managed by an OA with enhanced firmware. The OA has partitioning capabilities, both for hard partitions (nPartition) and for virtual partitions (vPar). You can manage the nPartitions and vPars through the OA without installing the 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 to manage partitions on HP Superdome 2 servers. This chapter addresses the following topics: • "Administration tool for nPartitions" (page 17) • "nPartition resources" (page 18) • "nPartition properties" (page 20) • "Blade resource attributes" (page 22) • "Operating system specific default values for nPartition attributes" (page 25) • "Partition State and RunStates" (page 26) • "Partition specifications (parspec)" (page 28) 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: • "Onboard Partition Manager" (page 17) • "Commands for configuring nPartitions" (page 17) 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 enables 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 are enhanced over the previous tools. The OA GUI can be launched either 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 within the privileges granted via parperm (with the exception of parperm, which is available only from the OA). Table 13 lists the nPartition configuration commands. NOTE: To execute partition commands from the operating system, you must have root user access. Table 2 nPartition Commands Command parcreate pardefault parmodify Description Creates a new nPartition. For more information, see help parcreate . Displays or changes default values of certain nPartition attributes. For more information, see help pardefault. Modifies an existing nPartition. For more information, see help parmodify.
