EFI/POSSE Commands

This section describes the EFI/POSSE commands developed for the server.

NOTE EFI and Pre-OS System Environment (POSSE) are similar. EFI is an Intel specification,

whereas POSSE is the HP implementation that aids HP support.

help

Provides information on the EFI shell commands.

Syntax

help [-b] <category>

help [-b] <cxnd>

help [-b] bch <bchmenu> <bchcmd>

Parameters

-b Enable page breaking

category Category of commands to view help on commands cmd Shell command name on

which to provide verbose information

bch Display the list of SCM commands and their corresponding EFI bchmenu BCH menu

name taken from the top level of the BCH menu bchcmd BCH command on which to

display information

Operation

If help is invoked with no parameters, it displays a list of shell command categories. To list all of the

commands within a category, the user should type “help <category>” (see examples). If invoked with the -b

switch, any output longer than one page pauses after each page is displayed. If a shell command name is

used as a parameter, verbose help is displayed for that command.

If help is invoked with the bch option, it displays a list of BCH commands and their corresponding

EFI/POSSE commands. It instructs the user to repeat the command line followed by a menu name for more

information on that menu. If help is invoked followed by bch and a menu name, it displays a list of

commands that appear under that BCH menu. The user may then invoke help followed by bch, the menu

name, and a BCH command name to display information on that command. This would point the user to

the command that has taken the place of that BCH functionality, or will inform the user that the

functionality no longer exists. As a shortcut, the user may enter help followed by BCH and a BCH

command name to go straight to that command.
