This section identifies and describes the different types of messages on the LCD and suggests corrective actions for problems associated with the message.

Some of the corrective actions require you to contact a service technician to replace hardware components.

The system console messages are logged to /etc/messages. If you contact Dell tech- nical support for service, report both the LCD and the console message.

If you are starting the system from a system boot diskette, the system does not dis- play the system prompt after it is started. Instead, it asks you for input. The LCD displays the following message: Waiting for user input.

For more information about starting the system boot diskette, refer to the Dell PowerVault 720N, 740N, and 760N System Administrator and Command Reference Guide .
