B Utilities

This appendix describes the boot console handler (BCH) utility that is part of the server.
High-level information is also provided on iLO MP. For complete information on the iLO MP,
see the HP Integrity and HP 9000 iLO MP Operations Guide on the HP website at
h20000.www2.hp.com/bizsupport/TechSupport.

Boot Console Handler

The BCH user interface provides the interface between you and the firmware through the menus
and simple commands.
The BCH is separate code in processor-dependent code (PDC). The BCH code has two purposes:
• Enables the bootstrap code to know which path to boot from.
• Enables you to interact with PDC to view and modify a set of specific system parameters.
Booting is standard for PA RISC, but can be transparent depending on the state of the autoflags
(boot, search, and start). If the autoflags are clear and you override autobooting, a boot
sequence ends in the interactive portion of BCH where modification and viewing of some system
parameters is possible.
NOTE:
When the autostart flag is off, autoboots are interrupted if a configuration change
occurs, which causes reduced performance. Therefore, you must intervene before booting to the
internal system loader (ISL).
The auto boot halts at the BCH prompt. Continue booting by entering boot.

BCH Commands

The PDC user interface provides the following types of commands:
