Behavior of Event History

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

Figure 1. Behavior of 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.
    • LSA starts maintaining the event history for Gateway, StandAlone, and DirectAgent installers from the time LSA is started.
