HP-UX 11i Version 2 Release Notes (October 2003)

General System Administration

HP Partitioning

Chapter 4

—The -u command option enables access to a remote partition using a

Web-Based Enterprise Management (WBEM) LAN connection.

—The -g command option enables access to a remote complex using an

Intelligent Platform Management Interface (IPMI) over LAN connection.

The -g option is valid only on those platforms which support IPMI (hp

Integrity Superdome, hp Integrity rx8620, hp Integrity rx7650, hp 9000

rp8420, and hp 9000 rp7420). IPMI is not available on the hp 9000

SuperDome, hp 9000 rp8400, or hp 9000 rp7410.

—The -h command option should only be used in combination with either the

-u or -g option.

— The arguments to the -u, -g and -h options consist of partition or complex

• Cell local memory (CLM) setting:

—The parcreate and parmodify commands have been enhanced to allow users to

specify/modify for each cell the amount of total cell memory that will be

configured as cell local (non-interleaved) memory. The arguments to the -c, -a

and -m options have been extended to include the value of cell local memory.

—The parstatus command has been enhanced to display cell local memory

information for individual cells and partitions.

• Integration with Instant Capacity On Demand (iCOD):

— Parmodify is fully integrated with iCOD.

• nPartition Configuration Privilege policy (restricted state) check:

— nPartition Configuration Privilege can be set to restricted or unrestricted state,

using the service processor menu, to prevent a superuser on one partition from

affecting the configuration of other partitions, or from performing tasks that

affect the complex.

—The parcreate, parmodify, parremove, cplxmodify, and frupower commands

have been enhanced to check for this restricted state. If the state is restricted, a

superuser on a partition cannot modify the complex profile (also known as Group

A Profile or Complex Configuration Data), including changes that only affect the

local partition: cell assignment, CLM parameters. Nor can the superuser modify

the cell profile (also known as Group C Profile or Partition Configuration Data)

of partitions other than then local partition. Finally, the superuser cannot power

on/off resources that are free or not owned.

Impact

• Itanium and PA-RISC: Starting with HP-UX 11i v2, the nPartition configuration

commands will work on both PA-RISC and Itanium-based partitionable platforms.

• CLM: The user can specify the cell local memory of any cell in the partition.

• nPartition Configuration Privilege: If set to the restricted state, the following

modifications will cause the command to fail:

— Create/remove partitions

— Add/delete cells to any partition in the complex.

— Modify the CLM parameters of any cell in the complex.
