Note
Ownership (O-bit) memory correctable or fatal errors (MESR <04> or
MESR <03> of the processor Register Subpacket set equal to 1) are
processor module errors, NOT memory errors.
5.2.7 Interpreting System Bus Faults Using ANALYZE/ERROR
If hardware register CESR <09> ( ) and/or CQBIC hardware register DSER
<07>, <05>, or <02> (
) is set equal to 1, there may be a problem with the
Q–bus or Q–bus option.
When CESR <09> is set equal to 1, examine the hardware register CIOEAR2
(
) to determine the address of the offending option.
Example 5–7 provides an error log showing a faulty Q–bus option. The
CIOEAR2 error register indicates the first UQSSP controller as the offending
address.
