MABRCFG: multi-adapter bridge configuration error.
The multi-adapter bridge hardware detected a configuration problem.
1. If you are working from the Service Action Log and there is a card position that is listed with this failing
item, then that is where the error is located. Continue with the next step in this procedure. Otherwise,
to determine the card location where the multi-adapter bridge configuration error is, go to "Bus PIP
PCIBUS-PIP1" on page 99. Return here after locating the card.
2. Use the following table to determine the corrective action.
Table 1. Multi-adapter bridge errors and meaning or corrective action
Problem or message
(these appear in upper case in the console)
Multi-adapter bridge has no IOP for the I/O adapters
Meaning or corrective action
v Step a. System code detected one or more I/O
adapters under the multi-adapter bridge specified in the
DSA, but no I/O processor to control them. The I/O
adapters are not available to the system. The SAL
entry lists the card locations controlled by the
multi-adapter bridge. If you do not have the card
locations listed in the SAL, find them by performing the
rest of step A. Otherwise, go to Step b (See page
361).
To locate the I/O adapters, search for the card
locations controlled by the multi-adapter bridge. The
multi-adapter bridge is in the DSA in word 7 of the
SRC. See "Breaking down the SRC" on page 63 (in
the Bus PIP overview) to determine the multi-adapter
bridge number. See the "Card positions" on page 65 (in
the Bus PIP overview) to determine all the card
locations controlled by the multi-adapter bridge.
v Step b. To make the I/O adapters available to the
system, install an I/O processor in a card slot controled
by the multi-adapter bridge to control the I/O adapters
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 the Locations
page for the frame type on which you are working).
