Failover a Controller Using the ILOM

You can use the Oracle Integrated Lights Out Manager (ILOM) to failover a Controller.

1. Log in to the Oracle FS System using the fscli with the primary administrator account.
2. Run the following command to enable secure shell (SSH) access:
   fscli system -modify -enableSsh [number of minutes]
3. Connect to the Pilot using SSH with the shared IP address of the Oracle FS System and log in using root / [root_password].
4. Connect to the Controller using SSH by running the following command on the Pilot:
   [root@pilot1 ~] cat /etc/nodenames
   172.30.80.2 WN2008fffffffffff2 WN2008000101000000 mgmtnode
   172.30.80.129 WN508002000158bb61 WN2008000101000001
   172.30.80.3 WN2009fffffffffffa
   172.30.80.128 WN508002000158bb60
   Note: You can connect to the Controller using SSH using either of the two IP addresses: 172.30.80.128 or 172.30.80.129.
5. Fail over the Controller by running the following command to shut down the Controller host:
   ipmitool chassis power off
   Chassis Power Control: Down/Off
6. Verify the Controller failure using the Oracle FS System Manager under: System > Alerts and Events > Status Summary.
   Note: Verify that the LUN and its resources are failed over to the alternate or buddy Controller and monitor the IOPs being generated from the LUNs and the SAN host using the Iometer interface.
