The multi-adapter bridge hardware detected a configuration problem.

Procedure

This is an unexpected error for this machine type. You should first resolve any other serviceable events on this machine.If this problem persists, contact your next level of support.

Support Information

About this task

The following is the information from the eServer™ product on which this machine is based. This information might be of use to your support engineer.

Note: This is background information for support use only. It is not necessarily applicable to this machine.

The multi-adapter bridge hardware detected a configuration problem.

In some cases, the user interface view of the serviceable event will list more than one card position for the location of this FRU. The problem might be with any one of the FRUs in those locations. When there is a list of locations in the location code for this FRU, the card locations will be separated by commas. A range of card positions will show the starting card position, a colon, and the ending card position.

Procedure

  1. Are you working from the service event user interface from an operating system, service processor, or the management console and are there card positions listed with this failing item?
    • Yes, the listed card positions are where the error is located. Continue with the next step.
    • No, go to MABIP53 to determine the card location where the multi-adapter bridge configuration error exists. Return here after locating the card, and continue with the next step.
  2. Use Table 1 to determine the corrective action.
    Table 1. Multi-adapter bridge errors
    Problem or message (these appear in uppercase in the console) Meaning or corrective action
    Multi-adapter bridge has no IOP for the I/O adapters.

    1. The system code detected one or more I/O adapters under the multi-adapter bridge specified in the DSA. There are no I/O processors to control them. The I/O adapters are not available to the system. The problem view lists the card locations controlled by the multi-adapter bridge.

      If you do not have the card locations listed in the problem view, find them by continuing with the next step. Otherwise, go to step 3.

    2. To locate the I/O adapters, search for the card locations controlled by the multi-adapter bridge. The multi-adapter bridge number is in the DSA (see DSA translation). See Card positions to determine all the card locations controlled by the multi-adapter bridge.
    3. To make the I/O adapters available to the system, install an I/O processor in a card slot controlled by the multi-adapter bridge or move the I/O adapters to a multi-adapter bridge with an I/O processor. When adding an IOP, place it in a card position that is ahead of the IOAs according to the "IOA Assignment Rules" table located in Finding part locations for the frame type on which you are working.
    Card type not supported in this slot.

    The system code detected a card type that is not supported in the multi-adapter bridge card location in which it is installed. Move the card to a location that will support that card type (check the installation instructions for the card to determine which card locations can support it).

    For reference codes where word 1 is B6006964 and word 4 is xxxx 2015, if the SAL does not show a card position for this error, then the card position can be determined by creating a Direct Select Address (DSA) from information in the reference code. To create the DSA, use the first 5 digits of word 7 and the 6th digit of word 5 followed by two zeros. Using this DSA, perform MABIP53 to determine the position of the card that is not supported in that slot.
    I/O processor removed from multi-adapter bridge card slot. The system code detected that an I/O processor card was located in that card location on the previous IPL. The I/O processor is no longer installed in that location.
    I/O adapter unavailable due to moved I/O processor card. The system code detected that the I/O processor which controlled the I/O adapter card specified in the DSA has been moved since the last IPL. The I/O adapter card is unavailable to the system.
    IOA removed from multi-adapter bridge slot. The system code detected that the card location specified in the DSA had an I/O adapter installed on the previous IPL. The I/O adapter is no longer installed in that card location.
    I/O adapter replaced by I/O processor card. The system code detected that the card location specified in the DSA had an I/O adapter installed on the previous IPL. The I/O adapter has been replaced by an I/O processor.
    Multi-adapter bridge configuration change or error. The system code detected a change in the multi-adapter bridge configuration or a configuration error since the last IPL.
    PCI I/O processor rejected assignment or removal of an IOA.

    The I/O processor's (IOP) Licensed Internal Code (LIC) rejected the assignment of an I/O adapter (IOA) to that IOP, or the IOP's LIC has rejected the removal of an IOA that the IOP owns.

    Word 5 of the reference code is the Direct Select Address (DSA) of the IOP. Word 7 of is the DSA of the IOA. To find the IOP and IOA, go to MABIP53 using the DSA.

    Use Hardware Service Manager (HSM) concurrent maintenance functions to assign or remove the IOA. See Hardware Service Manager for details.

    Assignment failures can result from either of the following conditions:
    • The IOP is already at its capacity to accept IOA assignments.
    • The IOA is not a type supported by the IOP.
    Corrective action:
    • Add another IOP for LIC to assign the IOA to if necessary.
    • Reassign the IOA to another IOP using concurrent maintenance.
    Removal failures:
    • This is a LIC problem and should be reported.
    • Contact your next level of support.
    Linux-owned slot - no IOP is allowed. An IOP card was found in a PCI bridge set that is allocated to a Linux® partition. The IOP will not be supported in this card position.
