HP Superdome 2 Partitioning Administrator Guide (5900-2540, December 2012)

NOTE: On SD2, for an nPar in npar mode, nPars are created with a default ILM/SLM distribution
of 1:7 when no value is specified for SLM. For an nPar created in vpar mode, the default value of
SLM will be 0% and ILM will be 100%. For more information, see “Modes: Switching between
nPars and vPars Modes ”.
Operating system specific default values for nPartition attributes
When an nPartition is created for a specific operating system type, the default values specific to
that operating system type are applied to the nPartition attributes. By default, hyperthreading is
enabled when nPartitions are created to run HP-UX. The default attribute values are applied without
a need for user intervention. The partition management software applies pre-determined OS specific
defaults when you create a partition for a specific operating system type. However, there is also
support for a new pardefault command, which displays the operating system specific attribute
values and allows users to change them if needed:
pardefault

Partition State and RunStates
Each nPartition has a State, and a RunState. The nPartition state indicates whether the nPartition
has booted and represents the power state of nPartition.
The nPartition runstate indicates the state of the nPartition with respect to OS instances. For more
information on RunState, see “RunStates” (page 26).
The nPartitions have one of the following states:
• Active nPartition
• Inactive nPartition
• Unknown
Active nPartition
An nPartition is active when a poweron operation is initiated on the nPartition and the firmware
boot process is started.
Inactive nPartition
An nPartition is considered inactive when it is not powered on. An nPartition is in inactive state
after it has been created or shut down.
