PCI expansion card (PIOCARD) problem isolation procedure
The hardware that controls PCI adapters and PCI card slots detected an error. The
direct select address (DSA) portion of the system reference code (SRC) identifies
the location code of the failing component.
The following table shows the syntax of a nine-word B700xxxx SRC as it might be
displayed in the event log of the management module.
The first word of the SRC in this example is the message identifier,
B7001111
. This
example numbers each word after the first word to show relative word positions.
The seventh word is the direct select address, which is
77777777
in the example.
