Setting the system enclosure type

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

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 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 I/O 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 I/O backplane. Failure to enter the correct enclosure serial number will result in logical partition mappings being incorrect.

Note: You cannot boot the system until valid values are entered for all fields in the enclosure-type information.

To perform this operation, your authority level must be one of the following:

Administrator
Authorized service provider

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

On the ASMI Welcome pane, specify your user ID and password, and click Log In.
In the navigation area, expand System Configuration > Program Vital Product Data.
Select System Enclosures. In the right pane, the current system enclosures are displayed.
Enter the desired settings for the Enclosure location, Feature Code/Sequence Number, and Enclosure serial number fields using the naming convention described in the ASMI help.
The value of the Enclosure serial number field is different from the serial number of the system. Set the Reserved field to blank spaces unless directed otherwise by service and support.
Click Save settings to update the system enclosure type information and save it to the VPD.
