Restart and Shutdown

Use the Restart and Shutdown module to restart or shutdown the Netra server.

If the Netra server is used by normal users, always try to notify them in advance if the system is to be shut down or restarted. All users that are logged in when the process is initiated receive messages on their terminals informing them that the system is about to be shutdown. If it is known that users are currently logged in on the server, it is best to specify a reasonable delay to give them time to close applications and log out.

    Check for new devices during restart? 

    If "Yes" is chosen, the operating system regenerates the list of devices attached to the Netra server upon start-up. Select yes if adding or removing a tape drive, CD-ROM drive, external hard disk, or network interface hardware to the server. Choice: Yes or No. 

    Delay (in minutes) 

    The time, in minutes, after which the Netra server shuts down or restarts. Users who are logged on receive broadcast messages during the countdown that the system is about to shut down. Use 0 for immediate restart or shutdown. 

  3. Click the OK button to confirm the operation.
