Setting the system enclosure type

Set values that uniquely identify the type of enclosures attached to the system.

About this task

When setting the system enclosure type, ensure that the enclosure serial number field matches the original value, which can be found on a label affixed to the unit. Updating the enclosure serial number field keeps the configuration and error information synchronized, and this information is used by the system when creating the location codes. This task must be done using the ASMI, not with the control panel. However, if you do not have access to the ASMI, the system will still operate without updating this information.

For example, when replacing the system backplane, you must re-enter the original enclosure serial number into the enclosure serial number field to overwrite the serial number that is recorded for the new system backplane. Failure to enter the correct enclosure serial number will result in logical partition mappings being incorrect.

Notes:
  • You cannot boot the system until valid values are entered for all fields in the enclosure-type information.
  • The field is case-sensitive. You must use uppercase letters.
To perform this operation, you must have one of the following authority levels:
  • Administrator
  • Authorized service provider

To change the system enclosure type, complete the following steps:

Procedure

  1. On the ASMI Welcome pane, specify your user ID and password, and click Log In.
  2. In the navigation area, expand System Configuration > Program Vital Product Data.
  3. Select System Enclosures. In the content pane, the current system enclosures are displayed.
  4. Enter the settings for the following fields using the information from the label that is located on your enclosure and the naming conventions described in the ASMI help:
    • Enclosure location
    • Feature Code/Sequence Number
    • Enclosure serial number: This value is different from the serial number of the system. The enclosure serial number can be found on a barcode label on the front, top, or rear of the system unit.
    • Reserved: Set the Reserved field to blank spaces unless directed otherwise by service and support.
  5. Click Save settings to update the system enclosure type information and save it to the VPD.
