Partitioning
This chapter provides information on partition identification and operations.
Partition Identification
Every partition has two identifiers: a partition number (the primary identifier from an internal perspective)
and a partition name (a more meaningful handle for administrators).
Partition Number
• A numeric value that is well suited for programmatic use and required by the hardware for configuring
routing, firewalls, etc. related to nPartitions.
• Once a partition has been created, its partition number cannot be changed. In effect, a different
partition number implies a different partition.
• Only one instance of an nPartition with a given partition number can exist within a complex.
• The range of partition numbers for nPartitions is 1 – 255.
Partition Name
• A partition name is a string value which directly conveys meaning.
• The name of a partition can be changed; this includes after the partition has been created and even if
a partition is active (such is the nature of an alias).
• A partition name should at least have one of the following non-numeric characters:
◦ a-z
◦ A-Z
◦ - (dash)
◦ _ (underscore)
◦ . (period)
Any other non-numeric character is not allowed in a partition name.
• nPartition names are unique within a complex.
Partition Power Operations
To activate an inactive nPartition, use the
poweron partition
command on the OA CLI.
To make an active partition inactive, use the
poweroff partition
command on the OA CLI.
To reboot an active nPartition, use the
reboot partition
command on the OA CLI.
To do a TOC on the nPartition and obtain a core dump, use the
toc partition
command from the OA
CLI.
To list all the nPartitions and their boot states and runstates (active or inactive states), use the
parstatus -P
command on the OA CLI.
For more information on the usage of these commands, see “Partition commands” in the
HPE Integrity
Superdome X and Superdome 2 Onboard Administrator Command Line Interface User Guide
.
PARSTATUS
The status of a partition and its assigned resources can be obtained by exercising various options
available with the OA CLI command
parstatus
. For more information on the
parstatus
command,
