For example, if a component is hot-plug removed from one slot and a different component is hot-plug inserted into another slot, Oracle ILOM might report the insertion occurring before the removal.
Oracle ILOM monitors each slot in the server in a sequential manner. Checking all slots completes a cycle. If after the cycle completes Oracle ILOM detects a change, it reports the change to the log file. If components are inserted into or removed from slots after the slots have been checked, Oracle ILOM might not report any change until the end of the next cycle.
Consider the example situation where a component is removed from slot A after Oracle ILOM has checked that slot, and the same component is inserted into a different slot F before Oracle ILOM has checked that slot. At the end of the cycle, Oracle ILOM reports that the component was inserted into slot F. In the next cycle, Oracle ILOM checks slot A and finds the component missing. At the end of this cycle, Oracle ILOM reports that the component was removed from slot A.
Workaround: Wait for at least 60 seconds between any hot-plug removal or hot-plug insertion operations to allow Oracle ILOM to cycle through the slots several times. The hot-plug operations should be reported in the order they occurred.
