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.
Bring a Controller Online Using the ILOM
You can use the Oracle Integrated Lights Out Manager (ILOM) to bring a
Controller online after testing the failover process works smoothly.
1
From the Pilot, connect to the alternate or buddy Controller using secure
shell (SSH).
2
Identify the alternate Controller by running the following command from
the Pilot:
cat /etc/nodenames
3
On the alternate Controller, run the following command:
ipmitool -H 169.254.2.9 -U root -P changeme chassis power on
This brings the failed Controller online.
4
Monitor the Oracle FS System Manager to verify that the Controller is back
online under: System > Alerts and Events > Status Summary
5
Clear the failure history by logging in to the Oracle FS System using the
primary administrator account and running the following command:
./fscli controller -reenable -controller [controller_name]
Command Succeeded
Failover and Bring Controller Online Using the Power Button
You can failover the Controller to the alternate or buddy Controller using the
power button on the Controller.
1
Manually press and hold the power button on the Oracle FS
SystemController for several seconds until the red LED is illuminated.
2
Bring the Controller back online after verifying that I/O is being performed
by manually pressing the power button for several seconds until the green
LED is illuminated on the Controller.
Perform a Drive Failure Test
Prior to copying production data to the Oracle FS System, perform a drive failure
test. A drive failure test verifies that the system is using the spare drive and that
the system can successfully rebuild a failed drive.
1
Using the Administrator account, log in to Oracle FS System Manager
(GUI), and navigate to System > Hardware > Drive Enclosure.
2
Select Actions > Drive Enclosure Console.
3
Click Next.
