Behavior of Event History
LSI Storage Authority supports retrieving the list of previous events, also known as event history.

LSA maintains the event history in three different log levels:
-
0
– Always read from firmware.Firmware maintains a separate space to save event history, which can be retrieved using the
LSA.conf
file.- MegaRAID Behavior – The source of an event is firmware. All events are persisted in firmware and can be retrieved at any point in time.
- Non-MegaRAID Behavior – The source of an event is Firmware, Driver, and StoreLIb. Firmware generated events can only be persisted and can be retrieved.
1
– By default, persists only non-MegaRAID events in the log file.- Non-MegaRAID events include IR/HBA.
255
– Persists all events in the log file.- LSA monitors the log location of the individual controller under $LSA_HOME/Conf/monitor/logs.
- The maximum number of events persisted in a file is 300. This can be configured through the
LSA.conf
file. - The maximum number of events that can be retrieved on a single page is 30. This can be configured through the
LSA.conf
file. - LSA maintains a set of events in the log file.
