Updating the Universal Unique Identifier (UUID)
The Universal Unique Identifier (UUID) must be updated when the system board is
replaced. Use the Advanced Settings Utility to update the UUID in the UEFI-based
server. The ASU is an online tool that supports several operating systems. Make
sure that you download the version for your operating system. You can download
the ASU from the IBM Web site. To download the ASU and update the UUID,
complete the following steps.
Note: Changes are made periodically to the IBM Web site. The actual procedure
might vary slightly from what is described in this document.
1. Download the Advanced Settings Utility (ASU):
a. Go to http://www.ibm.com/systems/support/.
b. Under Product support, select System x.
c. Under Popular links, select Tools and utilities.
d. In the left pane, click System x and BladeCenter Tools Center.
e. Scroll down and click Tools reference.
f. Scroll down and click the plus-sign (+) for Configuration tools to expand the
list; then, select Advanced Settings Utility (ASU).
g. In the next window under Related Information, click the Advanced Settings
Utility link and download the ASU version for your operating system.
2. ASU sets the UUID in the Integrated Management Module (IMM). Select one of
the following methods to access the Integrated Management Module (IMM) to
set the UUID:
v Online from the target system (LAN or keyboard console style (KCS) access)
v Remote access to the target system (LAN based)
v Bootable media containing ASU (LAN or KCS, depending upon the bootable
media)
3. Copy and unpack the ASU package, which also includes other required files, to
the server. Make sure that you unpack the ASU and the required files to the
same directory. In addition to the application executable (asu or asu64), the
following files are required:
v For Windows based operating systems:
– ibm_rndis_server_os.inf
– device.cat
v For Linux based operating systems:
– cdc_interface.sh
4. After you install ASU, use the following command syntax to set the UUID:
asu set SYSTEM_PROD_DATA.SysInfoUUID <uuid_value> [access_method]
Where:
<uuid_value>
Up to 16-byte hexadecimal value assigned by you.
[access_method]
The access method that you selected to use from the following
methods:
v Online authenticated LAN access, type the command:
[host <imm_internal_ip>] [user <imm_user_id>][password
<imm_password>]
