Table 3-2 RunStates for nPartition
(continued)
Description
Runstate
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
