9.7 Advanced Settings Utility (ASU)
The Advanced Settings Utility (ASU) allows you to modify your server firmware settings from
a command line. It supports multiple operating systems, such as Linux, Solaris, and Windows
(including Windows Preinstallation Environment (PE)). The firmware settings that can be
modified on the eX5 platform include UEFI and IMM settings.
You can perform the following tasks by using the ASU:
Modify the UEFI CMOS settings without the need to restart the system and access the F1
menu.
Modify the IMM setup settings.
Modify a limited set of VPD settings.
Modify the iSCSI boot settings. To modify the iSCSI settings through ASU, you must first
manually configure the iSCSI settings through the server setup utility.
Remotely modify all of the settings through an Ethernet connection.
ASU supports scripting environments through batch-processing mode. Download the latest
version and the Advanced Settings Utility User’s Guide from the Advanced Settings Utility
website:

9.7.1 Using ASU to configure settings in IMM-based servers
ASU 3.x supports configuring settings on servers with integrated management modules
(IMMs), such as the eX5 family of servers. The ASU uses the same set of commands and
syntax that is used by previous versions of the ASU tool. Certain commands are enhanced to
manage and display groups of settings, including new classes that are used as filters if you
display the supported settings by using the show set of commands.
In IMM-based servers, you configure all firmware settings through the IMM. The ASU can
connect to the IMM locally (in-band) through the keyboard console style (KCS) interface or
through the LAN over USB interface. The ASU can also connect remotely over the LAN
(out-of-band).
When the ASU runs any command on an IMM-based server, it attempts to connect and
automatically configure the LAN over a USB interface, if it detects that this interface is not
configured. The ASU also provides a level of automatic and default settings. You have the
option of specifying that the automatic configuration process is skipped, if you have manually
configured the IMM LAN over a USB interface. We recommend that the ASU configure the
LAN over a USB interface.
See the User’s Guide for the Advanced Settings Utility at the following website for more
details:

Tip: After you use the ASU to change settings, you must reset the IMM before you flash
new firmware; otherwise, the changes to the settings might be lost. To reset the IMM, use
the following ASU command:
asu rebootimm
