You can create a new nPartition by using any one of the
following procedures: Creating a new nPartition involves specifying one or more
cells in a server complex, setting various attributes for the cells, and optionally
specifying other nPartition settings. The settings you specify then are used
to create a new nPartition, which has assigned to it the cells you selected. At least one cell in each nPartition must be connected
to an I/O chassis that has core I/O attached. To boot an operating system
from disk, the nPartition also must have a boot device and associated PCI
card. When creating an nPartition, follow the HP nPartition requirements
and guidelines. HP recommends only specific sets of nPartition configurations. Procedure 6-2 Creating a New nPartition (nPartition Commands) From the command line, use the parcreate command
to create a new nPartition. You also can use the parstatus and parmodify commands
to list nPartition and complex details and modify nPartition settings. Login to a system
that enables you to list the current cell assignments and details. For example,
login to HP-UX running on an existing nPartition in the server complex, or
login to a system with the Enhanced nPartition Commands or Partition Manager
Version 2.0. Plan your nPartition configuration by
selecting which cells will comprise the new nPartition. Use the parstatus -AC command to
list all unassigned (available) cells in the server complex. # parstatus -AC

You can select any of the cells listed to create the new
nPartition; only the cells that are not "absent" are present within the server
complex. All cells that you choose must meet the hardware requirements
for nPartitions (for example, they all must have the same firmware revision).
The cells also must form an HP-recommended nPartition configuration. At least
one cell must have an I/O chassis with core I/O. After confirming
that cells you have chosen would establish a valid nPartition configuration,
use the parcreate -c... command to create a new nPartition
with the cells. The -c... option differs slightly for the
nPartition command releases. When using the parcreate command,
only specify the -B option if you want the nPartition to
be booted and become active. The -B option causes parcreate to
immediately boot the newly-created nPartition past the default shutdown for
reconfig state. By not specifying -B, the new nPartition
can be further modified because it will remain inactive at the shutdown for
reconfig state (until you boot it using the BO command
at the service processor Command Menu). If creating a single-cell nPartition, use just one -c option. To create a multiple-cell nPartition, specify the -c option
multiple times (once for each cell) issuing a single command line. For example, with the Original nPartition Commands, the
following command creates a one-cell nPartition: # parcreate -c4:base:y:ri -c6:base:y:ri
Partition Created. The partition number is : 1
# |
When parcreate successfully creates
a new nPartition, it reports "Partition Created" and reports the nPartition
number ("partition number is..."). If parcreate detects any problems or
issues when creating an nPartition, it lists them in its output. If it cannot
create the nPartition, parcreate reports "Command failed"
along with more details. parcreate Command: Cell Attributes Differences for
nPartition Command Releases. The parcreate command's -c... option
specifies the cell number(s) and attributes to be used when creating the new
nPartition. For the Enhanced nPartition Commands, an additional cell local
memory attribute is optional. Both the syntaxes are given in the following
list. For the Original nPartition Commands, the parcreate command's -c option
is as follows: -c cell:[cell_type]:[use_on_next_boot]:[failure_usage] This option specifies the cell ID (cell) to be
assigned to the nPartition. The only valid cell_type value is: base (base
cell, the default). The valid use_on_next_boot values for
cells are: - y
Participate in reboot (the default). - n
Do not participate in reboot.
The only valid failure_usage value
is: ri (reactivate with interleave, the default).
For details, refer to the parcreate(1M) manpage. For the Enhanced nPartition Commands, the parcreate command's -c option
is as follows: -c cell:[cell_type]:[use_on_next_boot]:[failure_usage][:clm] This option specifies the cell ID (cell) to be
assigned to the nPartition. The cell_type, use_on_next_boot,
and failure_usage attributes are the same as supported
with the Original nPartition Commands. You can specify the clm value in either
of two forms: percentage or absolute amount of memory. Percentage cell-local memory (CLM). The percent
number can be any number in the range 0-100 with a suffix of %. This number is rounded to 12.5%, 25%, 37.5%, 50%, 62.5%, 75%, 87.5%
or 100%. If the cell contains less than 4 GBytes of memory, then the percentage
is rounded to 25%, 50%, 75% or 100%. Percentages are rounded up or down to
the nearest value, but are not rounded up to 100%. Absolute CLM specification. (The default.) The
absolute number is interpreted as an absolute number of gigabytes of memory
and can optionally have a suffix of GB. As needed, an absolute CLM specification is rounded up to the nearest
0.5 GBytes.
If the clm value is rounded, the command
reports the final value used.
For details, refer to the parcreate(1M) manpage.
Use the parmodify command
to modify the configuration of the new nPartition and set the nPartition name
(-P), boot paths (-b, -s,
and -t), and any core cell choices (-r).
On HP Integrity servers, nPartition boot paths must be set from the local
nPartition. When using the parmodify command,
you must use the -p# option to specify
the partition number for the nPartition. Use the partition number that the parcreate command
reported in the previous step. # parmodify -p1 -P "hostname05"
Command succeeded.
# parmodify -p1 -r0/4 -r0/6
Command succeeded.
# parmodify -p1 -b 4/0/1/0/0.9
Command succeeded.
# |
When each modification takes place, parmodify reports
"Command succeeded". Otherwise it reports any problems. You can specify each configuration option on a separate
command line or can combine all options into a single, longer command line. For details on the various options for modifying nPartition
settings, refer to the parmodify(1M) manpage. Use the parstatus
-V -p# command to list all details about
your newly created and configured nPartition. If
any configuration details need to be modified, use the parmodify command
before you boot the nPartition in the next step. # parstatus -V -p1

Boot your newly-created
nPartition past boot-is-blocked to make it active and make its system boot
environment available. (The BCH environment is provided
on HP 9000 servers; the EFI environment is provided on HP Integrity servers.) Use the BO command at the service
processor Command menu to boot the nPartition. Once the nPartition is booted, you can access its system
boot environment through its console. Use the service processor Console menu
(enter CO at the service processor Main Menu).
Procedure 6-3 Creating a New nPartition (Partition Manager) You can create a new nPartition by using Partition Manager. When using Partition Manager Version 1.0, use the Partition Create Partition action. When using Partition Manager Version 2.0, use the nPartitionCreate nPartition action. Access Partition
Manager. For details on accessing Partition Manager
or other tools, see “Tools for Configuring nPartitions”. Run the Partition
Manager task wizard for creating a new nPartition. From
Partition Manager Version 1.0, select the PartitionCreate Partition action. From Partition Manager Version 2.0, select the nPartitionCreate nPartition action. Partition Manager guides you through the steps it requires
for creating a new nPartition. Exit Partition
Manager. From Partition Manager Version 1.0, select
the FileExit action. From Partition Manager Version 2.0, select Log
off parmgr or exit the Web browser when finished.
