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

You can use the Advanced System Management Interface (ASMI) to verify and set certain values for an expansion unit. These values include the machine type, model, and serial number (MTMS) and the configuration ID.

1. Log in to ASMI.
2. Expand System Configuration.
3. Click Configure I/O Enclosures > Clear Inactive Enclosures.
4. If you were directed here from a part replacement procedure, you must restore information that was contained in the nonvolatile storage of the original part. The expansion unit MTMS must be restored, and you might also be required to set or change the configuration ID (power control network identifier).
   Note: In the replacement part, the nonvolatile storage that contains the expansion unit MTMS value is uninitialized. Following the Clear Inactive Enclosures task, the system detected the uninitialized value and replaced it with an obvious, unique value. The replacement MTMS value is formatted as TMPx.xxx.xxxxxxx, where x is any character 0 - 9 or A - Z. The expansion unit location code, which you must use to select the expansion unit for operations in this task, became UTMPx.xxx.xxxxxxx.
5. From the ASMI utility, expand System Configuration.
6. Click Configure I/O Enclosures.
7. Verify the configuration ID and MTMS data by completing the following steps:
   1. Compare the Power Control Network Identifier value shown for the expansion unit you are working with to the following Power Control Network Identifier (configuration ID) values:
      • 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 Type-Model and Serial number column values for the expansion unit you are working with to the type, model, and serial values on the expansion unit label. The expansion unit location code displayed in the Location code column appears in one of the following formats:
      • UTMPx.xxx.xxxxxxx, where x is any character 0 - 9 or A - Z.
      • UTTTT.MMM.SSSSSSS, where TTTT is the enclosure type, MMM is the model, and SSSSSSS is the serial number.
      Note: A 10009132 informational log is produced during an initial program load (IPL), or if a temporary MTMS was assigned to an expansion unit that was added concurrently. The temporary MTMS causes the expansion unit to have a location code of UTMPx.xxx.xxxxxxx, where x is any character 0 - 9 or A - Z.
   3. If any changes must be made, go to step 8. Otherwise, go to step 18.
8. If the system is powered on to the firmware running state, go to step 9. If the system is powered on to the firmware standby state, go to step 10.
9. Choose from the following options:
   • If the configuration ID must be changed, perform the following steps:
     1. Read the following notes.
     2. Power off the I/O expansion unit.
     3. Go to step 10.
   • If the MTMS data must be changed and any expansion unit resources are owned by active system partitions that are running the AIX® or Linux operating system, perform the following steps:
     1. Read the following notes.
     2. Power off the I/O enclosure.
     3. Go to step 10.
   • If none of the previous options apply, go to step 10.
   Notes:

   • Do not disconnect the power cables after powering off the expansion unit.
   • If the expansion unit does not display immediately on the service utility that is used to power off the expansion unit, refresh the utility periodically for up to 10 minutes. If the expansion unit does not display during this timeframe, go to step 1 and repeat this procedure.
   • If you were directed here from a part replacement procedure, remember to use the new UTMPx.xxx.xxxxxxx location code when you select the expansion unit to power off.
   • 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 control panel of the logical partition where you were instructed to use panel function 69. Do this even though the expansion unit is already on.
10. From the ASMI utility, expand System Configuration.
11. Click Configure I/O Enclosure > the expansion you are working with > Change settings.
12. If in step 7 you determined that the Power Control Network Identifier (configuration ID) value was not correct, enter the correct value now.
13. If in step 7 you determined that the Type-Model and Serial number values were 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.
14. Click Save settings to complete the operation.
15. 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 working with by expanding System Configuration > Configure I/O Enclosures. Do not use the Back button to do this.
16. If the system is powered on to firmware standby state and you entered a new power control network identifier (configuration ID) in step 12, the expansion unit will power off and back on automatically. If this is the case, go to step 18. Otherwise, go to step 17.
17. If you powered off the expansion unit in step 9, read the following notes to power on the expansion unit.
    Notes:

    • If the system is managed by an HMC, power on the expansion unit by using the Serviceability > Hardware > Power On/Off Unit task 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 task, restart the task periodically for up to 10 minutes until the values you entered are shown.
    • 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 power indicator light on the expansion unit control panel to go off, wait an additional 30 seconds, and then reconnect the power cables. The expansion unit will power on automatically.
18. Log off and close the ASMI.
19. Return to the procedure that sent you here.
