Preboot Menu Command Summary

The preboot menu includes the following commands.

Command

Description

boot

Boots the ILOM. The preboot menu exits and the ILOM boots.

Note - This command executes a modified boot sequence that does not offer the choice to select the diagnostic level, or to interrupt the boot sequence and return to the preboot menu. To execute the normal boot sequence, use the reset warm command instead.

vers

Displays version information including the hardware type, board rev, ILOM rev, revisions of PBSW and recovery U-Boot. Shows the checksum integrity of the images, and the preference between redundant images.

help

Displays a list of commands and parameters.

show

Displays a list of SP settings.

edit

Starts an interactive dialog that prompts and changes settings one-by-one. See Using the edit Command and Configuring the Preboot Menu For Remote Access for details.

diag

Runs the U-boot diagnostic tests in manual mode. See the x86 Server Diagnostics Guide for more on U-boot diagnostic tests.

host

Initiates various activities related to the host.

clearcmos – Clears CMOS and BIOS passwords.
console – Connects the SP console to host serial console.

Note - To quit, type: Ctrl \ q
show – Shows information about the host state.
enable-on – Enables the front-panel power button, which is usually disabled unless the ILOM is running.

Caution - If you start the host when the ILOM is off, the BIOS does not send error events, or power messages to the SP. This can cause all server modules to lose power.
hard-off – Turns the host off.

net

{ config | dhcp | ping | flash }

config - Starts a dialog that allows you to change the ILOM’s network settings.
dhcp - Changes the network addressing from static to dhcp.

ping - Sends a ping.
flash - Downloads an ILOM firmware image. See Recovering the SP Firmware Image
Type help net command for more details on these commands.

reset

warm - Resets the SP without affecting a running host.
cold - Resets the SP and the host. It has the effect of powering off the server module.

users - Resets all configured user information.
password - Resets the ILOM root password to the default. See How to Reset the Root Password to the Factory Default for more details.
ilom_conf - Resets configuration settings but preserves SP network and baudrate, preferred, and check_physical_presence.
most - Resets the SP data storage, but preserves network and baudrate, preferred, and check_physical_presence settings.
