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.

1. Download the Advanced Settings Utility (ASU) from thehttp://www.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=TOOL-ASU&brandind=5000016.
2. Select one of the following methods to access the IMM to set the UUID:
   • Online from the target system (LAN or keyboard console style (KCS) access)
   • Remote access to the target system (LAN based)
   • Bootable media containing ASU (LAN or KCS, depending upon the bootable media)
     Note: IBM provides a method for building a bootable media. You can create a bootable media using the Bootable Media Creator (BoMC) application from thehttp://www.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=TOOL-BOMC&brandind=5000016. In addition, the Windows-based and Linux-based toolkits are also available to build a bootable media.
3. Copy and unpack the ASU package, which also includes other required files, to the server. Be sure to unpack the ASU and the required files to the same directory. In addition to the application program (asu or asu64), the following files are required:
   • For Windows-based operating systems:
     • ibm_rndis_server_os.inf
     • device.cat
   • For Linux-based operating systems:
     • cdc_interface.sh
4. After you unpack ASU, use the following command syntax to set the UUID:

   asu set SYSTEM_PROD_DATA.SysInfoUUID uuid_value [access_method]

   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:

   • Online authenticated LAN access, use the following syntax:

     [host imm_internal_ip] [user imm_user_id][password imm_password]

     Where:

     imm_internal_ip

     The IMM internal LAN/USB IP address. The default value is 169.254.95.118.

     imm_user_id

     The IMM account (1 of 12 accounts). The default value is USERID.

     imm_password

     The IMM account password (1 of 12 accounts). The default value is PASSW0RD (with a zero, not the letter O).

     Note: If you do not specify any of these parameters, ASU uses the default values. When the default values are used and ASU is unable to access the IMM by using the online authenticated LAN access method, ASU automatically uses the unauthenticated KCS access method.
     The following commands are examples of using the user ID and password default values and not using the default values:

     Example that does not use the user ID and password default values:
     asu set SYSTEM_PROD_DATA.SYsInfoUUID uuid_value user user_id
     password password
     
     Example that does use the user ID and password default values:
     asu set SYSTEM_PROD_DATA.SysInfoUUID uuid_value

   • Online KCS access (unauthenticated and user restricted):

     You do not need to specify a value for access_method when you use this access method.

     Example:
     asu set SYSTEM_PROD_DATA.SysInfoUUID uuid_value

     The KCS access method uses the IPMI/KCS interface. This method requires that the IPMI driver be installed. Some operating systems have the IPMI driver installed by default. ASU provides the corresponding mapping layer. See the Advanced Settings Utility User's Guide for more details. You can access the guide from thehttp://www.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=TOOL-ASU&brandind=5000016..

   • Remote LAN access. Use the following syntax:
     Note: When you use the remote LAN access method to access IMM using the LAN from a client, the host and the imm_external_ip address are required parameters.

     host imm_external_ip [user imm_user_id[[password imm_password]

     Where:

     imm_external_ip

     The external IMM LAN IP address. There is no default value. This parameter is required.

     imm_user_id

     The IMM account (1 of 12 accounts). The default value is USERID.

     imm_password

     The IMM account password (1 of 12 accounts). The default value is PASSW0RD (with a zero, not a letter O).

     The following commands are examples of using the user ID and password default values and not using the default values:

     Example that does not use the user ID and password default values:
     asu set SYSTEM_PROD_DATA.SYsInfoUUID uuid_value host imm_ip
     user user_id password password
     
     Example that does use the user ID and password default values:
     asu set SYSTEM_PROD_DATA.SysInfoUUID uuid_value host imm_ip

   • Bootable media:

     You can also build a bootable media using the applications available at thehttp://www.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=TOOL-CENTER&brandind=5000016..

5. Restart the blade server.
