Getting to Know Your Integrity Server
The hardware, firmware, and software supported might vary
significantly from system to system. Integrity servers come in
many different configurations. The hardware, utilities, and hardware
configuration procedures might differ significantly across models,
and even across versions of the same model. This manual provides
basic information about the firmware, hardware, and utilities offered
on Integrity servers. This information is not meant to replace
the hardware documentation. For the most up-to-date and relevant information
for your particular model, refer to the hardware documentation
for your Integrity server. The hardware documentation includes
model-specific illustrations to guide you. The latest version of documentation
for your server can be found online at the following Web sites:
http://docs.hp.com/en/hw.html

Refer also to the HP OpenVMS Version 8.2-1 for Integrity Servers New Features and Release Notes and the Cover Letter for HP OpenVMS Version 8.2-1 for Integrity Servers for the latest information about firmware and software requirements and for considerations for your Integrity server.
Entering
Commands at Integrity Server Console Interfaces
When entering commands for the Integrity server, if you press
the Delete key on a VTxxx terminal (or press the
key you have mapped to send the DEL/RUBOUT character code in your
terminal emulator), the last character typed is not deleted, as
would be expected on an OpenVMS Alpha system. Integrity server
facilities use Ctrl/H to delete the last character typed. For information
about how to remap a terminal to use Ctrl/H instead of DEL/RUBOUT,
refer to
Using the Delete or Backspace Key with Integrity Server Utilities.
Integrity
Server Tools
Integrity servers include multiple interfaces for working
with various aspects of the server or server complex.
The Management Processor (MP), which is
also known on entry-class Integrity servers as Integrated
Lights-Out (iLO), is available on most systems. It provides
a service interface that allows access to all hardware and, in a
complex, all nPartitions. MP is always available,
even when the main power source is turned off (MP can operate on
standby power). On cell-based servers (rx7620,
rx8620, and HP Integrity Superdome), MP is available whether or
not nPartitions are configured or booted in the server complex.
You can navigate from MP to and from the operating system (if it
is booted).
The Extensible Firmware Interface (EFI) provides support for operating system loaders and allows you to configure the firmware and control the booting environment. EFI is accessible only when the operating system is not booted. On cell-based servers, each nPartition has a separate EFI console interface. EFI provides support for managing nPartitions. The EFI interface is available from an nPartition console only when the nPartition is in an active state but has not booted an operating system.
You can move from the EFI interface to MP and back again. Similarly, you can move from MP to the operating system and back.
Cell-Based
Server Terminology
A cell-based server--such as the HP rx7620, rx8720,
or HP Integrity Superdome server--is a hardware complex
that can run one or more operating systems and that supports dividing
hardware resources into nPartitions. Thus, it enables you to configure
a complex into one large system or into several smaller systems.
All processors and memory are contained in cells, each of which can be assigned for exclusive use by an nPartition. An nPartition defines a subset of the server hardware resources that is used as an independent system environment. An nPartition has its own EFI system boot interface and each nPartition boots and reboots independently. Each nPartition provides both hardware and software isolation so that hardware or software faults in one nPartition do not affect other nPartitions within the same server complex.
By using HP software-based nPartition management tools, you can configure nPartition definitions for a server without physically modifying the server hardware configuration. The main administration tools for nPartitions are the Partition Manager, which provides a graphical interface, and the nPartition Commands, which provide a command-line interface. Versions of these interfaces are provided on HP-UX and Microsoft® Windows® systems. nPartition Commands are also available on Linux® systems. MP and EFI can also perform nPartition administrative tasks. Slightly different tool sets and capabilities are available on different server models. For more information, refer to your hardware documentation. In addition, refer to the HP System Partitions Guide: Administration for nPartitions .
