Table 3-2 RunStates for nPartition (continued)
DescriptionRunstate
This is a partition definition in an alternate parspec.ALT_DEFINED
The nPartition is either running or is ready to run virtual partitions.RUN_VPARS
The status is not known. This may reflect an error condition or a transitionary state
while partition states are being discovered.
UNKNOWN
1 An inactive nPartition can be in the DEACTIVATING, RESETTING or MCA RunStates, if it encounters an error or
is interrupted during the activation process.
Partition Specifications (parspec)
A parspec is a collection of data that defines the configuration of a specific nPartition, including
any defined vPars.
You may use the parspec functionality to do the following:
• Save nPartition and vPartition configurations.
• Modify configurations
• Create partitions
The following are the key features of parspecs.
• Every parspec defines only one nPartition.
• Multiple nPartitions must be described in multiple parspecs.
• A nPartition can be created from a specified parspec.
• Every nPartition that exists has a parspec associated with it (referred to as a current
parspec), and there can be only one current parspec for a given nPartition.
• Any parspec not associated with an existing nPartition is an alternate parspec.
• Every parspec has a unique name (scope of uniqueness is a complex).
• Parspecs can be managed through the partition commands.
• The vPar database resides within a parspec.
Creating a Partition Specification
You can create a parspec using the following command in the OA CLI:
• parcreate -C PartitionSpec:[:create_partition_flag]
Where PartitionSpec is the name of the parspec to be created. The
create_partition_flag can take the following values:
— y – the corresponding nPartition is created.
— n – the corresponding nPartition does not get created. This is the default.
NOTE:
— The -C option creates only a partition specification.
— All user supplied arguments to parcreate that are used to define an nPartition may
be used to create a parspec.
Creating an nPartition from a Partition Specification
You can create an nPartition and assign resources using the parspec with the help of the following
commands:
• Use the following command to create an nPartition using PartitionSpec
parcreate -Z PartitionSpec
