Console log and the RLM

The RLM 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 RLM stores them in the console log, which resides in a 96-KB buffer in its main memory.

The console log can store approximately 2,000 lines of system console messages. When the buffer is full, the oldest messages are overwritten by the newest messages.

The console log persists as long as the RLM has power from either of the storage system’s power supplies. Since the RLM operates with standby power, it remains available even when the storage system is power-cycled or turned off.

If the autosupport.content option is set to complete, and a “down filer,” a system hang, or a reboot loop condition occurs, the console logs are attached to the AutoSupport messages sent by the RLM.

You display the contents of the console log with the RLM CLI system log command.
