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.
POSSE is an HP implementation of EFI that aids HP support.
NOTE: The output shown for these EFI commands are samples, and might differ depending
upon your server and its configuration.
help
Provides information on the EFI Shell commands. The help command also aids administrators
familiar with the BCH menus to adjust to their equivalent functions in EFI.
Syntax
help [-b] <category>
help [-b] <cmd>
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 BCH 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 you issue the help command with no parameters, a list of shell command categories displays.
To list all of the commands within a category, enter help <category>. If help is issued with
the -b option, any output longer than one page pauses after each page displays. If a shell
command name is used as a parameter, verbose help displays for that command.
If you issue the help command with the bch option, it displays a list of BCH commands and
their corresponding EFI/POSSE commands. It instructs you to repeat the command line followed
by a menu name for more information on that menu. If you issue help within the bch option
and a menu name, it displays a list of commands that appear under that BCH menu. You can
then issue help followed by bch, the menu name, and a BCH command name to display
information about that command. This points you to the EFI command that has taken the place
of that BCH functionality, or will inform the user that the functionality no longer exists.
Alternately, enter help followed by bch and a BCH command name to go straight to that
command.
