Using the ASMI to verify and set the configuration ID and MTMS value

You can use the Advanced System Management Interface to verify and set the configuration ID and machine type, model, and serial number (MTMS) value for your system.

1. Login in to ASMI.
2. Expand System Configuration.
3. Select Configure I/O Enclosures.
4. Select Clear Inactive Enclosures.
5. If you were directed here from a replacement procedure, the expansion unit that was replaced contained the nonvolatile storage where the expansion unit machine type-model-serial (MTMS) was stored. It is necessary to restore the expansion unit MTMS now. It may also be necessary to set or change the expansion unit configuration ID (power control network identifier).

   The nonvolatile storage where the expansion unit MTMS value is stored in a new replacement expansion unit is uninitialized. The system will detect the uninitialized value and assign an obvious, unique value of the form TMPx.xxx.xxxxxxx, where x can be any character 0-9 and A-Z. As a result, the expansion units location code will change to UTMPx.xxx.xxxxxxx. You must use the new UTMPx.xxx.xxxxxxx location code in the instructions below when selecting the expansion unit to power off and selecting the expansion unit to change settings for.

6. From the ASMI utility, expand System Configuration.
7. Select Configure I/O Enclosures.
8. Verify the configuration ID and MTMS data
   1. Compare the power control network identifier value shown for the expansion unit you are working with to the power control network identifier (configuration ID) values in the following list.
      • 0x84 for 5096 and 5296 expansion units
      • 0x88 for 7311-D11 and 5790 expansion units
      • 0x89 for 5088 and 0588 expansion units
      • 0x8A for 5094, 5294, 5096, and 5296 expansion units
      • 0x8B for 5095 and 0595 expansion units
      • 0x8C for 7311-D20 expansion units
      • 0x8D for 7314-G30 and 5796 expansion units
      • 0x8E for 5802 and 5877 expansion units
   2. Compare the values shown on the ‘Type-Model' and ‘Serial number' columns for the expansion unit you are servicing to the type, model, and serial values on the label located on the expansion unit. The expansion unit location code format will be either UTMPx.xxx.xxxxxxx or UTTTT.MMM.SSSSSSS, where TTTT, MMM, and SSSSSSS are the enclosure type (TTTT), model (MMM), and serial number (SSSSSSS).
      Notes:

      • A 10009132 information log will be produced following a platform IPL, or when an expansion unit is added indicating that a temporary MTMS was assigned to an expansion unit. The temporary MTMS has the following location code format, UTMPx.xxx.xxxxxxx. This is an indication that the MTMS should be updated.
      • Serial numbers are case sensitive. (All alphabetic characters contained in the serial number must be entered as a capital letter.)
   3. If any changes must be made, go to step 9. Otherwise go to step 21.
9. If the server is powered on to the firmware running state, go to step 10. If the server is powered on to the firmware standby state, go to step 11.
10. Choose from the following options:
    • If the configuration ID must be changed, perform the following steps:
      1. Read the notes below.
      2. Power off the I/O enclosure.
      3. Go to step 11.
    • If the MTMS data must be changed and the system has partitions running the AIX® or Linux operating system and any of the resources in the expansion unit are owned by active partitions running AIX or Linux, perform the following steps:
      1. Read the notes below.
      2. Power off the I/O enclosure.
      3. Go to step 11.
    • If neither of the above statements apply, go to step 11.
    Note:

    • Do not disconnect the ac power cables after powering off the expansion unit.
    • If the expansion unit is not immediately displayed on the service utility used to power off the expansion unit, refresh the utility periodically for up to ten minutes until it does. If it still is not displayed, go to step 1 and repeat this procedure.
    • Remember to use the new UTMPx.xxx.xxxxxxx location code when selecting the expansion unit to power off if you were directed here from a replacement procedure.
    • If the procedure that directed you here involved powering off the expansion unit and while powering off the expansion unit you were instructed to use panel function 69 to power on the expansion unit, perform panel function 69 now (with the control panel set to manual mode) from the system unit control panel. Do this even though the expansion unit is already on.
11. From the ASMI utility, expand System Configuration.
12. Select Configure I/O Enclosure.
13. Select the expansion unit you are working with.
14. Select Change settings.
15. If in step 8 you determined that the power control network identifier (configuration ID) value is not correct, enter the correct value now.
16. If in step 8 you determined that the Type-Model and Serial number values are not correct, enter the correct values now.
    Note: Serial numbers are case sensitive. All alphabetic characters contained in the serial number must be entered as a capital letter.
17. Click Save settings to complete the operation.
18. Verify that the values you just entered are reflected in the Power Control Network Identifier, Type-Model, Serial number, and Location code columns for the expansion unit you are servicing. Do not use the browser Back button to do this. Rather, expand System Configuration. Then select Configure I/O Enclosures.
19. If the server is powered on to a firmware standby state and you entered a new power control network identifier (Configuration ID) in step 15, the expansion unit will power off and back on automatically. If this is the case, go to step 21. Otherwise go to step 20.
20. If you powered off the expansion unit in step 10, read the notes below to power on the expansion unit.
    Notes:

    • If the system is not managed by an HMC, disconnect all power to the expansion unit by disconnecting the cables from the power supplies on the expansion unit. Wait for the display panel to go off, wait an additional 30 seconds, and then reconnect the power cables. The expansion unit will power on automatically.
    • If the system is managed by an HMC, power on the expansion unit using the Power On/Off Unit utility on the HMC. If the values you just entered are not immediately reflected in the location code of the expansion unit in the Power On/Off Unit utility, restart the utility periodically for up to ten minutes until the values you entered are reflected.
21. Log off and close the ASMI.
22. Return to the procedure that sent you here.
