HP Superdome 2 Partitioning Administrator Guide HP-UX 11i v3 (766170-001, May 2014)

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
An nPartition may report a Partition State of Unknown and 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 or the virtual partitions, except parstatus, vparstatus and force poweroff.
Any active OS instances continue to run unhindered even when the nPartition is in 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, shutdown all OS instances and force
poweroff the partition from the OA.
To clear this state:
1. Shutdown all OS instances in the nPartition
2. Force poweroff the nPartition from the OA
3. Poweron the nPartition from the OA
This is an example of parstatus output for a partition in DETACHED state:
parstatus -P

(GB)** characters)
=== ======================= ======= ====== ====== ============= ===============
1 Unknown/DETACHED OK 1 2 10.0/84.0 nPar0001
To activate an inactive nPartition, either use the poweron command on the OA CLI, or the
Momentary Press button on the Virtual Devices tab on the nPartition page in the OA GUI.
To make an active partition inactive, use the poweroff command on the OA.
To list all the nPartitions and their boot states and run states (active or inactive states), use the
parstatus -P command on the OA CLI.
parstatus -P

To list all the nPartitions and their boot states in the OA GUI, use the Complex nPartition Summary
page.
