You can manage partitions on HP Superdome 2 systems using the following methods: • From the OA: The OA Graphical User Interface (GUI) and Command Line Interface (CLI) support partition management user interfaces. NOTE: The initial release of HP Superdome 2 does not support iCAP CLIs on the OA. • From the partitions: The operation system based (Legacy) partition management command interfaces are supported from the partition OS instance, until these operations are targeted to that vPar instance. Operations targeting other vPars need explicit authorization using the "parperm" command (available only from the OA). However, vparstatus does not need explicit permissions and it can display status of all vPars contained in an nPar, irrespective of which vPar OS instance it is invoked from. • From a Central Management System (CMS): The HP Systems Insight Manager (HP SIM) and other plug-ins from the CMS can be used to manage partitions. HP Superdome 2 terminology Table 1 (page 8) lists the terms specific to HP Superdome 2. Table 1 HP Superdome 2 terminology Term Resource path LAN on Motherboards (LoMs) Monarch OA Partition specifications (parspecs) Standby/Redundant OA Socket Blades IOX / I/O Bay Enclosure Description On HP Superdome 2 platforms, resources in the complex are identified by a resource path. The resource path describes the physical hardware resources in a hierarchy of elements called entity. Each resource path consists of a hierarchical list of entity numbers. The hierarchy describes the parent-child relationships. The parent is listed to the left of the child. Each entity number is relative to the parent. The separator between the entity numbers is the slash (/) character. For more information on resource path, see help resourcepath. For example, the resource path 1/2 identifies blade 1 in enclosure 2 of a HP Superdome 2 complex. LoMs represent the network ports on the blade. This is the active instance of the Onboard Administrator (OA). Platforms that have OA based partition management support partition specifications (parspecs). A parspec is a collection of data that defines the configuration of a specific nPartition. It includes the virtual partitions in the nPartition if the customer has defined any virtual partitions. For more information on partition specifications, see "Partition specifications (parspec)" (page 28). This is the Onboard Administrator instance that can perform the role of the Active or Monarch OA in the event of a failure of the Monarch OA. A socket on HP Superdome 2 represents the Field Replacable processing unit on a blade. Each socket presents 4 CPU-cores. A unit that contains CPU-cores, memory and onboard Network Interface cards (NICs). A blade is the equivalent of a cell (in cell-based platforms) in terms of being the unit of assignment for defining nPartitions. A unit that can be added to an HP Superdome 2 complex to add I/O slots to the complex. An IOX provides upto 12 PCIe slots. The unit that hosts either a blade or an IO Bay in an HP Superdome 2 complex. 8 Introduction
