Introduction

Performing nPartition management tasks

Chapter 1

Creating a Genesis Partition for a server complex

To create a Genesis Partition, use the management processor CC command to specify

that an initial, one-cell nPartition be created within the server complex. The complex

must not have any nPartitions defined or all nPartitions must be shutdown for reconfig

(inactive).

Creating additional nPartitions in a server complex

You can use one of two methods to create nPartitions in a complex where one or more

nPartitions already are defined:

Create a new nPartition locally

will be created and use Partition Manager’s Create Partition task, or

issue the parcreate command.

Create a new nPartition remotely

will be created and use Partition Manager’s Create Partition task.

You can also execute the parcreate command using either the WBEM

or with IPMI-over-LAN method. For remote administration using

WBEM, the tool accesses the nPar Provider running on an nPartition

in the target complex (for example, with the -u... -h... options). For

remote administration using IPMI over LAN, the tool accesses the

management processor (for example, with the -g... -h... options).

Modifying nPartitions

Modifying an nPartition involves using an nPartition administration tool to revise one or

more parts of the server Complex Profile data, which determines how hardware is

assigned to and used by nPartitions.

•Use parmodify or Partition Manager from an nPartition running in the same

complex as the nPartition. Some nPartition details can also be modified locally from

an nPartition console by using EFI Shell commands.

•Use parmodify or Partition Manager running on a remote management station or

Windows system.

— Using WBEM, the tool accesses the nPar Provider running on an nPartition in the

target complex. Use the -u... -h... set of parmodify options (or equivalent

Partition Manager login options).

— Using IPMI over LAN, the tool accesses the management processor of the target

complex. Use the -g... -h... set of parmodify options (or equivalent Partition

Manager login options).

Modifying nPartitions includes the following tasks:

Assign (add) or unassign (remove) cells from an nPartition:

In the Partition Manager Hardware tab, select the desired nPartition

and cell and use a menu path of

nPartition > Assign cell(s) / Cell > Assign

cell(s)

or nPartition > Unassign cell(s) / Cell > Unassign cell(s).

Or, use the parmodify -p# -a#... command to add a cell or the

parmodify -p# -d#... command to remove a cell from the specified

nPartition (-p#, where # is the partition number).
