NOTE: In some HP documents, you might see the acronym POSSE used in place of or in
combination with EFI. EFI is an Intel specification of an interface between firmware and the
operating system. POSSE (Pre-OS System Environment) is the HP implementation of EFI
that extends the EFI Shell and EFI Boot Manager to include additional features for managing
hardware and system boot options.
• Management Processor (MP)
Management Processor (or, on entry-class Integrity servers, iLO) provides both local and
remote access for controlling the system console, reset/power management, and transfer of
control (TOC) capabilities. It also enables you to monitor tasks and display detailed
information about various internal subsystems. On cell-based servers, MP is a complex-wide
tool and is always available, even if nPartitions are not configured or booted in the server
complex. In contrast, EFI does not operate as a complex-wide tool and is only available when
the nPartition is in an active state but has not booted an operating system; each nPartition
has its own EFI interface. Using MP, you can select the partition for which you want EFI
access. You can access all hardware and nPartitions in the complex. The following is a brief
summary of MP’s main features:
— Console connectivity
As a console interface, MP enables you to interact with EFI and to power the server on
or off; ultimately, it can function as the OPA0: terminal port on OpenVMS.
— Virtual Front Panel (VFP)
MP provides a virtual front panel that you can use to monitor the front panel LEDs
from a remote location.
— Command interface
MP provides an extensive menu system and a command-line interface.
— Multiple, simultaneous viewers
Multiple users can access the MP console or a particular nPartition console. Only one
user at a time is allowed interactive access. All other users have read-only access. (Output
from the interactive user is reflected to the read-only users currently accessing the
console.) Access to MP can be restricted by password-protected user accounts.
— Availability/standby power
MP is available whenever the system is connected to a power source, even if the server’s
main power switch is in the off position.
— Accessibility
MP is accessible in several ways, including by direct monitor connection using a terminal,
PC, laptop or desktop computer connected to the MP serial port (with certain Integrity
servers, you can also use a VGA monitor and USB keyboard and mouse); by modem
through an EIA-232 port; or by Telnet or Web browser on the LAN. MP is accessible
through Secure Shell (SSH), which is provided by TCP/IP Services for OpenVMS. This
method of access is more secure than any of the other methods.
— Console log
MP records recent output from the system console. The cl command enables you to
view the recorded information.
— Event logs
MP includes event logs that include information about system events and booting. The
sl command displays the contents of system status logs.
On some systems, such as the rx1600, MP is optional. For more information about MP options
and commands, see the appropriate hardware documentation.
