1.2.1.3.2 Powering Off Oracle Exadata Storage Servers

Oracle Exadata Storage Servers are powered off and restarted using the Linux shutdown command.

The following command shuts down Oracle Exadata Storage Server immediately: 

# shutdown -h now

When powering off Oracle Exadata Storage Servers, all storage services are automatically stopped.

If you use the -r option, then the shutdown command shuts down and then restarts Oracle Exadata Storage Server. The -now option indicates you want to stop the server immediately. 

# shutdown -r now

Another system command to reboot a server is the reboot command. However, shutdown -r now is the preferred command to restart a server. You should never use the reboot -f command to shut down Oracle Exadata Storage Servers.

Note:

Do not perform successive shutdown or reboot commands, which is essentially the same as reboot -f.

Note the following when powering off Oracle Exadata Storage Server:

  • All Oracle Database and Oracle Clusterware processes should be shut down prior to shutting down more than one Oracle Exadata Storage Server.

  • If you are powering off the entire Oracle Exadata Rack and the system uses Oracle Exadata Exascale, then stop the Exascale cluster before you shut down the Oracle Exadata Storage Servers. See Stop the Exascale Cluster.

  • Powering off one Oracle Exadata Storage Server does not affect running database processes or Oracle Automatic Storage Management (Oracle ASM).

  • Powering off or restarting Oracle Exadata Storage Servers can impact database availability.

  • The shutdown commands can be used to power off or reboot Oracle Exadata Storage Server.
