Managing Partitions - basics The partition management architecture on HP Superdome 2 is designed to adapt to the new hardware and firmware architecture. This OA-based architecture supports integrated nPartition and virtual partitioning. nPartitions can be further subdivided using virtual partitions. You interact with both partition types in the same way. User interfaces for routine operations such as boot, shutdown, and reset are common across vPars and nPartitions, and are available from both the OA user interfaces. Each virtual partition has a separate console and presents the UEFI Shell just like an nPartition. Operating System (OS) install operations and OS boot methods for an nPartition and a virtual partition are the same. The core of partition management functionality now resides on the management processor or OA. A partition is identified by its unique number and name. The range of partition numbers for nPartitions is 1 to 255, and the range of partition numbers for virtual partitions is 1 to 255. Partition numbers cannot be modified but the name can be changed. nPartition names must be unique within a complex, and virtual partition names must be unique within an nPartition. Both nPartitions and virtual partitions have a state and a run-state. A state can be active or inactive. The runstates of an nPartition or vPar are described in "Partition State and RunStates" (page 26). NOTE: The terms "nPartition" or "nPar" and "virtual partition" or "vPar" are interchangeably used throughout the document. nPartitions An nPartition is a hard partition that contains one or more blades, and zero or more I/O bays. nPartitions can run a single OS (either a standalone OS or an HPVM host), or can be divided into virtual partitions. An nPartition on an HP Superdome 2 system is similar to an nPartition on cell based servers. On HP Superdome 2, you can create an nPartition without assigning any resources (no blade or I/O bay resources assigned). However, you must assign resources to such an nPartition before it can be activated or powered on for use. An nPartition provides electrical isolation. You can use the OA to perform the following nPartition functions: • Create a new nPartition. • Modify an existing nPartition. 10 Partitioning in HP Superdome 2
