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.
4
From the Drive Enclosure list, select a Drive Enclosure.
Note: You can select any Drive Enclosure from the list. To ensure expedient
rebuild times, perform a drive failure test on the highest-tier Drive
Enclosure in the system.
