HP-UX Virtual Partitions Release Notes (A.04.03)

Known Problems and Workarounds
System Activity Events Reported Through IPMI by EMS
Chapter 3 41
Workaround
Note that in a vPars environment, when system events are reported via
EMS either from system firmware or an OS instance, the system events are
decoded and reported on all virtual partitions. The OS instance that is
shown as sending the event is not necessarily indicative of the actual virtual
partition that encountered the problem.
The Reporting Entity ID is the only clue to which virtual partition reported
the problem. The output will be similar to the following:
Reporting entity ID: 6 ( Cab 0 Cell 0 CPU 6 ) (possibly from one vPar)
