Management interface options

You can manage nPartitions remotely using one of two management interfaces: the Intelligent
Platform Management Interface (IPMI) and the Web-Based Enterprise Management (WBEM)
infrastructure. This section provides a brief overview of these interfaces.

Intelligent Platform Management Interface (IPMI)

On cell-based HP Integrity servers, the MP supports the Intelligent Platform Management Interface
(IPMI). IPMI is an industry-standard interface that defines common, message-based interfaces
to platform management hardware and common records for describing devices and their
characteristics. The IPMI specification supports extensions, such as the nPartition and server
complex management features introduced by HP. On cell-based servers, the MP supports two
of the communication paths defined by the IPMI specification: Block Transfer and IPMI over
LAN.

IPMI Block Transfer (IPMI BT)

IPMI Block Transfer (IPMI BT) provides a communication path between the MP and the operating
system running on an nPartition. IPMI BT uses the MP device driver and a hardware buffer on
each cell to establish a private path (using the block transfer hardware on the core cell) from each
nPartition to the MP. On Windows, the device driver that provides the IPMI BT interface is called
the "HP Health Driver."
The nPartition Configuration Privilege setting enables you to control the access of a user
managing an nPartition on a complex. To set the nPartition Configuration Privilege, run the
PARPERM command using the MP. The nPartition Configuration Privilege has two settings:
Unrestricted
Restricted
The nPartition Configuration Privilege does not restrict deallocation of processors across nPartition
boundaries. When the nPartition Configuration Privilege is restricted, some management tasks
require IPMI over LAN instead.

IPMI over LAN

IPMI over LAN enables the management tool to communicate directly (without going through
an nPartition) with the MP through its LAN port. To enable IPMI LAN access to the MP, use the
SA command at the MP Command menu. The MP accepts IPMI requests at its LAN port only

station used to remotely manage the complex. Also, you
must set the admin IP address for individual nPartitions
using the nPar commands. This cannot be done with any
other tool.
Extensible Firmware Interface (EFI) provides support for
nPartition management. The EFI interfaces are accessible
from an nPartition console when the nPartition is in an
active state but has not booted an operating system.
that provides access to all hardware and nPartitions in the
complex. The MP is always available, whether or not any
nPartitions are configured or booted in the server complex.

Restricts use of the IPMI BT interface to the following capabilities:
• Retrieving information about the server, including everything displayed
by Partition Manager and the parstatus command.
• Changing the local nPartition's Partition Configuration Data.
• Manipulating any of the attention indicators (LEDs).
• Powering cells and I/O chassis belonging to the local nPartition.
