Description
An informational message is something that was recorded for
audit purposes, usually a user action or a change of states that is
normal behavior.
A warning is not as severe as an error, but if possible, the
condition should be corrected before it becomes an error. It
might also be a condition that requires additional monitoring or
maintenance.
An error typically indicates a failure or critical condition that
impairs service or an expected function.
1. This message could occur with messages about
other Processor configuration problems. Resolve
those messages first.
2. If the problem persists, ensure that matching
processors are installed (i.e., matching option part
numbers, etc)
3. Verify that the Processor's are installed in the
correct sockets according to the service information
for this product. If not, correct that problem.
