Ma_Brdg - IBM iSeries Series Hardware Problem Analysis And Isolation

Problem or message
(these appear in upper case in the console)
PCI I/O processor rejected assignment or removal of an
IOA
Linux owned slot - no IOP is allowed
This ends the procedure.

MA_BRDG: multi-adapter bridge.
The problem is the multi-adapter bridge hardware on a system bus.
1. Is the location information for this failing component available in the Service Action Log?
v No: Continue with the next step.
v Yes: Use the location information in the Service Action Log, and go to step 4 (See page 364).
2. Were you sent here by an A6xx xxxx or B6xx xxxx SRC, and no location information was available in
the Service Action Log?
v No: Continue with the next step.
v Yes: Record the bus number value, BBBB, in word 7 of the SRC. See "Breaking down the SRC" on
page 63 (located in the Bus PIP Overview topic) for help in determining the bus number. Search for
the bus number in HSM or the System Configuration Listing to determine which frame or I/O tower
contains the failing component. Record the frame or tower type, and go to step 4 (See page 364).
Meaning or corrective action
The I/O processor's (IOP) licensed internal code (LIC)
has rejected the assignment of an I/O adapter (IOA) to
that IOP, or the IOP's LIC has rejected the removal of an
IOA which the IOP owns.
Word 5 of the SRC is the Direct Select Address (DSA) of
the IOP. Word 7 of the SRC is the DSA of the IOA.
1. To find the IOP go to "Bus PIP PCIBUS-PIP1" on
page 99 using the DSA in word 5 of the SRC.
2. To find the IOA go to "Bus PIP PCIBUS-PIP1" on
page 99 using the DSA in word 7 of the SRC.
Use HSM concurrent maintenance functions to assign or
remove the IOA. See Hardware Service Manager in the
(TM)
iSeries Service Functions
using the HSM concurrent maintenance functions.
Assignment failures can be from:
v The IOP already being at its capacity to accept IOA
assignments.
v The IOA is not a type supported by the IOP.
Corrective action:
v Add another IOP for LIC to assign the IOA to if
necessary.
v Re-assign the IOA to another IOP using concurrent
maintenance.
Removal failures:
v This is a LIC problem and should be reported.
v Call your next level of support.
An I/O processor 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.
