Basics Of Npartition Creation - HP Rp7410 - Server - 0 MB RAM Administrator's Manual

Basics of nPartition Creation

Creating an nPartition involves using an nPartition administration tool to assign one or more
cells in a complex to the new nPartition. At the time an nPartition is created you also can optionally
specify various configuration options for the nPartition, such as its name, cell use-on-next-boot
values, and other details. After an nPartition is created you can modify the nPartition, as described
in "Basics of nPartition Modification" (page
NOTE: When creating an nPartition, follow the HP nPartition requirements and guidelines.
HP recommends only specific sets of nPartition configurations. For nPartition configuration
requirements and recommendations, see
The method you choose for creating an nPartition can depend on whether you are creating the
first nPartition in a complex, creating a "Genesis Partition" for a complex, or creating an additional
nPartition in a complex that already has one or more nPartitions defined.
• Creating the First nPartition in a Server Complex
you can do so either by creating a Genesis Partition or by using an nPartition administration
tool to remotely manage the complex using IPMI over LAN.
— All cell-based servers support creating a Genesis Partition. See
Partition for a Server Complex" (page
— Only cell-based servers based on the HP sx1000 or sx2000 chipset support remote
administration using IPMI over LAN.
From a system with the Enhanced nPartition Commands, use the parcreate command
-g... -h... set of options. Or from Partition Manager Version 2.0 use the Switch
Complexes dialog to connect to the complex and use the nPartition Create nPartition
action.
For remote administration details see

Creating a Genesis Partition for a Server Complex
•
the service processor (MP or GSP) CC command to specify that an initial, one-cell nPartition
be created within the server complex. To create a Genesis Partition, the complex either must
have no nPartitions defined, or all nPartitions must be shutdown for reconfig (inactive). For
details see
Creating Additional nPartitions in a Server Complex
•
create additional nPartitions in a complex where one or more nPartitions already are defined:
either use parcreate or Partition Manager from an nPartition running in the complex, or
use the remote administration feature of those tools running on a system outside the complex.
For a detailed procedure see
— Creating a New nPartition Locally — To create a new nPartition in the same complex
where parcreate or Partition Manager is running at least one nPartition must be
booted with an operating system that has the nPartition tools installed.
Login to HP-UX on the nPartition and issue the parcreate command, or access Partition
Manager running on the nPartition and use its Create nPartition action.
— Creating a New nPartition Remotely — To remotely create a new nPartition in a complex,
do so either by using the Enhanced nPartition Commands version of parcreate, or
by using Partition Manager Version 2.0.
Only cell-based servers based on the HP sx1000 or sx2000 chipset support remote
administration.
Both parcreate and Partition Manager support two methods of remote administration:
WBEM and IPMI over LAN. For remote administration using WBEM the tool remotely
accesses a booted operating system running on an nPartition in the target complex (for
41).
