How to display information about the storage system and the BMC

The BMC provides several ways to display information about the storage system and the BMC itself. You can display real-time information using the commands in admin or advanced mode, or you can display information stored in the BMC's System Event Log (SEL) or Console Log.

You can also view the information displayed in the AutoSupport messages generated by the BMC. Most of the information is stored in the SEL or in captured console messages.

• BMC CLI commands that display real-time information
  Using the BMC CLI commands in admin mode, you can view information such as the BMC version and configuration, system console log history, storage system events, and storage system power status. Using the BMC CLI commands in advanced mode, you can view information about the BMC battery and active BMC network services.
• System Event Log and the BMC
  The BMC has a non-volatile memory buffer that stores up to 512 system events in a System Event Log (SEL). The SEL is stored in onboard flash memory on the BMC. If the buffer is full, new messages are dropped and Data ONTAP does not run, in order to preserve the diagnostic history.
• System console log and the BMC
  The BMC monitors the storage system console regardless of whether administrators are logged in or connected to the console. When storage system messages are sent to the console, the BMC stores them in the system console log, which resides in a 64-KB buffer in its main memory.
• AutoSupport messages for systems with BMC
  For storage systems with BMC, there are two additional types of AutoSupport messages—BMC-generated AutoSupport messages about the storage system, and storage system-generated AutoSupport messages about the BMC.
