Uuid For Npartitions; Npartition States - HP integrity superdome x Service Manual

Command Line Interface User Guide.

UUID for nPartitions

The partition firmware subsystem will generate an unique nPar UUID when a user creates an nPartition.
The UUID will be communicated to system firmware, which places the UUID on the SMBIOS for the OS
and the management applications to pick up and use this as "Universally Unique Identifiers" of the
partition. The UUID would also be available for the manageability and the deployment tools and
applications through established SOAP interfaces that can query UUID. Customers can view the UUID of
the nPartition by issuing parstatus –p <npar_id> -V under the field "Partition UUID".

nPartition states

The nPartition state indicates whether the nPartition has booted and represents the power state of
nPartition. The nPartitions will 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.
Unknown nPartition
An nPartition might report a partition state of "Unknown" and a runstate of "DETACHED" after an OA
restart. This state is possible when the firmware is not able to identify the correct nPartition state due to
internal firmware errors at OA startup. The state is persistent and can only be cleared by force powering
off the nPartition from the OA. A partition in this state will not accept any partition operation for the
nPartition, except parstatus and force poweroff. Any active OS instances continue to run unhindered
even when the nPartition is in an Unknown state.
If any attempts are made to issue partition administration operations, the following error occurs:
Error: Partition state unavailable due to firmware errors. All OS instances
running in this partition will continue unimpacted.
NOTE:
To clear this partition state:
1. Shut down all OS instances in the nPartition.
2. Force power off the nPartition from the OA.
3. Power on the nPartition from the OA.
This is an example of parstatus output for a partition in the DETACHED state:
parstatus -P
