    1 Introduction The HP Integrity Superdome 2 servers (HP Superdome 2) are scalable systems based on blade system architecture. HP Superdome 2 systems support HP nPartitions and HP-UX Virtual Partitions (vPars v5). This administrator guide describes the steps to plan, create, and manage partitions – nPartitions and virtual partitions –...
  • Page 8: Hp Superdome 2 Terminology

    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.

Managing Partitions – basics The partition management architecture on HP Superdome 2 is designed to adapt to the new hardware and firmware architecture.
  • Page 11: Virtual Partitions (vpars)

    Boot an existing nPartition. Remove an nPartition. Rename an nPartition. Reset an nPartition. Assign and unassign resources such as blades and I/O bays. You can define many possible configurations for an nPartition complex, and then control the configurations or partitions that can exist at any given point in time. This is possible by using partition specifications.
  • Page 12: Commands: Partition Commands Logging

    NOTE: — Run the help command at the OA prompt, to view the current list of Partition Help pages. — The Partition Help pages are: nPartition Commands ◦ parcreate, parmodify, pardefault, parremove, parstatus, and parperm vPartition Commands ◦ vparcreate, vparmodify, vparreset, vparremove, vparstatus, vparresources, resourcepath and vecheck vparresources and resourcepath are not commands.
  • Page 13: Cases Where Logging Occurs

    Cases where logging occurs Logging occurs when the commands either change or affect the state of partitions. The commands include parcreate, parmodify, parremove, vparboot, vparcreate, vparenv, vparremove, vparmodify, and vparreset. Constraints and restrictions to logging The command line text will be logged on only the partition from which the command was executed.
  • Page 14: Related Software Licensing

    NOTE: HP Integrity servers running the new HP sx3000 chipset are quad core (4 cores per processor or per socket), but HP-UX licensing is per socket or per processor. Therefore, one per socket software license is required for each quad-core processor. The processor and the socket represent a processing unit, and includes 4 cores.
  • Page 15 NOTE: Use the getconf command or the confstr() call to obtain the unique identifiers. Do not use the uname -i command, which does not report unique IDs for nPartition systems. To guarantee compatibility on current and future platforms, use the interfaces to getconf(1) and confstr(3C) to retrieve unique machine identifiers.

  • Page 17: Getting Started With Npartitions

    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.

  • Page 20: Active And Inactive Blades

    Active and inactive blades Blades that are assigned to an nPartition and have been booted are active blades whose resources (processors, memory, and on-board I/O) can be actively used by software running in the nPartition. Blades that are Inactive are either not assigned to an nPartition (recognized by the empty Par Num field against the blades in the parstatus command output) or are assigned to an nPartition that is not yet powered on (partition status Inactive/DOWN in the parstatus command output).
  • Page 21: Partition Names

    Partition names Specifies the name of the nPartition. The parcreate —P name command is used to create an nPartition with a name associated with it. An nPartition name must have at least one of the following non-numeric characters: a-z, A-Z, dash (-), under-score (_), or period (.). An nPartition name with the same format as the default name can only be specified if the specified name matches the nPar number.
  • Page 22: Blade Resource Attributes

    SLM can be specified as a blade resource attribute when creating nPartitions. The remaining available memory after specifying SLM is specified automatically as Interleaved Memory (ILM). For more information, see “Blade resource attributes” (page 22). Blade resource attributes With HP Superdome 2 nPartitions, blade attributes are specified using the parcreate and parmodify commands.

Additionally, there is also a user specified attribute “failure_usage” for a blade and I/O bay. You can set this attribute to indicate whether the partition to which the nPartition resource or blade or I/O bay is assigned should be activated or not if it is found faulty.
  • Page 79: Planning Your System For Virtual Partitions

    7 Planning Your System for Virtual Partitions Planning Your Virtual Partitions A virtual partition is created by specifying the resources needed for the vPar. The resources that can be assigned to a vPar are: CPU-cores - You must either specify the number of CPU-cores that are part of the vPar, or specify the resource paths of individual CPU-cores, or specify the socket resource paths and quantity from where the CPUs are to be assigned.
  • Page 80: Minimal Hardware Configuration

    Minimal Hardware Configuration Every bootable virtual partition must have at least: 1 CPU-core On HP Integrity Superdome 2, by default, a vPar is created with zero CPU-cores. Such a vPar cannot boot. System memory (sufficient for HP-UX and the applications in that partition) A boot disk (when using a mass storage unit, check your hardware manual to verify that it can support a boot disk) Although it is not required for booting a virtual partition, you can add a LAN card for networking.
  • Page 81: Cpu-core: Adding And Deleting By Total

    NOTE: On an HP Integrity Superdome 2 system, a vPar is created with zero CPUs by default. Therefore, the default cpu:::[min] value is zero. The default cpu::::[max] value is the total number of CPUs in the nPartition. The virtual partition must be in the “Down” state to set the minimum or maximum value. The total count of CPUs in the virtual partition must always be greater than or equal to min and less than or equal to max.

    Example To create a virtual partition with 3 CPUs, set num to 3: vparcreate -N nParID -p vParID -a cpu::3 vparcreate -p nparID:vParID -a cpu::3 vparmodify With the vparmodify command, you can use: -a option to add num CPUs to the virtual partition, -d option to delete num CPUs from the virtual partition, -m option to modify (set) to num the number of CPUs assigned to the partition.

    Deleting CPU-cores Summary If you want to control which CPU-core is deleted, use the same method—by SLP, by resource path, or by count-on your deletion command line that you used on your addition command line. CPU Allocation On HP Integrity Superdome 2, the parstatus command provides all the required CPU information from the OA without installing or booting to the nPar mode.

    NOTE: The memory granules are not the actual memory DIMMs. You can specify the granularity for SLM and ILM separately. However, the following applies to both types of memory: Memory granularity is specified during the creation of nPartition. Any modification thereafter requires you to reboot the nPartition.
