Auto-Start use cases

A System Engineer is tasked with server administration.

System reboot

The Administrator must reboot a Cloverleaf server. The Administrator shuts down all processes on the server and issues the reboot command. Upon start-up the auto-start scripts ensure the Cloverleaf Integration Service is running and starts all sites.

System failure

The clustering software has detected a network loss on the active server. The clustering software takes these actions:

  • Calls a stop on the active server with the failure:
    • Stops the Cloverleaf application.
    • Unmounts the shared file system.
    • Releases the IP address.
  • Calls a start on the standby/passive server:
    • Mounts the shared file system.
    • Assigns the IP address
    • Starts the Cloverleaf application and sites.
