parcreate(1M)

For OA Based Partition Management Systems

parcreate(1M)

the parspec change policy is enabled (default), the affected partition operation is

continued with available or modiﬁed resources or attributes after making the

required changes in the parspec. If the parspec change policy is disabled, the

affected partition operation fails and no changes are made to the parspec.

-Z parspec_name Creates an nPartition from a partition speciﬁcation (parspec). On successful nParti-

tion creation, the parspec speciﬁed with the

-Z option is made the current parspec

for the nPartition. When the

-Z option is not speciﬁed, a default parspec of the for-

mat

psNNNN is created and made the current parspec (where NNNN is a 4 digit

nPartition number). If a parspec with the same name exists, it is overwritten.

When this option is speciﬁed, any other option specifying resource assignments or

nPartition attributes is not allowed.

Note: the

-Z and -C options are mutually exclusive.

RETURN VALUE

The

parcreate command exits with one of the following values:

0 Successful completion.

1 Error condition occurred.

ERRORS

syslog contains additional description of errors encountered during partition operations. Users can

view the OA syslog from the OA using the "SHOW SYSLOG OA" command.

Error: System unable to accept partition commands

The above error message is printed out under the following circumstances:

• Attempting to run command from an OA other than the active OA in enclosure 1.

• System has been shut down (e.g. with POWEROFF XFABRIC, or ambient overtemp).

• The OA has not ﬁnished initializing.

In the above scenarios, please ensure the system and OA are completely up and you are running the com-

mand from the active OA in enclosure 1.

EXAMPLES

Create a new nPartition

nextPartition

with two blades. The blades are located in enclosure 1, slot 1

and slot 2. This example uses the default values for the blades. The default blade_type will be

base.

The default failure_usage policy will be

ri. The default use_on_next_boot will be y. By default there will

be no SLM for the blades.

parcreate -p nextPartition -a blade:1/1:::: -a blade:1/2::::

Create the new two-blade nPartition nextPartition from the previous example that uses IO slots in IOX

enclosure 5, bay 1.

parcreate -p nextPartition -a blade:1/1:::: -a blade:1/2:::: \

-a io:5/1:

Create a new nPartition myPartition with two blades. One of the blades is located in enclosure 1, slot 3.

The blade_type for the blade is base. The failure_usage policy for this blade is ri. The SLM value for

this blade is 1 GB. The other blade is located in enclosure 2, slot 6. The blade_type and failure_usage

are not speciﬁed for this blade. The use_on_next_boot for both blades is y.

parcreate -p myPartition -a blade:1/3:base:y:ri:1GB \

-a blade:2/6::y::

Re-create the two-blade nPartition nextPartition from the saved parspec nextPartition_copy.

parcreate -Z nextPartition_copy

Create a new nPartition slmPartition with three blades. The blades are located in enclosure 1, slot 1, slot

2, and slot 3. This example speciﬁes 50% of the memory on the ﬁrst two blades to be conﬁgured as SLM

and 25% of the memory on the third blade to be conﬁgured as SLM.

parcreate -p slmPartition -a blade:1/1::::50% \

-a blade:1/2::::50% -a blade:1/3::::25%
