6944 Missing or failed I/O processor cards
A system bus appears to be empty. If the bus is not empty, two
I/O processors in consecutive slots may be missing or broken.
If there are broken I/O processors, then another more serious
SRC has occurred. Otherwise find the bus number for this
failure from the Product activity log and use the system
configuration list to verify the configuration of the I/O
processors on that bus.

For this reference code the failing item list presented in the
"Service Action Log" can be different from the failing item list
documented here. That is due to the differences in system
models and features installed.
If the "Service Action Log" is available then use the failing item
list presented there for servicing this reference code.
If the "Service Action Log" is not available then use the failing
item list documented here. By following the procedures in the
symbolic FRUs listed here you will isolate to the correct FRU
