Upgrading a Standalone Appliance to a Clustered Configuration (BUI)
Use this procedure to upgrade a standalone appliance to a clustered configuration.
Note - It is strongly recommended that you use the BUI to configure clustered controllers.
Before You Begin
Check for the following:
-
The second controller is a new controller or a controller that has been reset to the factory settings. See Performing a Factory Reset in Oracle ZFS Storage Appliance Customer Service Manual.
-
Both controllers must be the same model. Note that the 7420 (with 2Ghz or 2.40GHz CPUs) is based on the same platform and can be clustered with the 7420 (with 1.86GHz or 2.00GHz CPUs).
-
The standalone appliance is powered on. There is no need to power down the standalone appliance during this procedure.
-
Connect the cluster cables between the standalone appliance and second
controller.
For cluster cabling details, see Connecting Cluster Cables in Oracle ZFS Storage Appliance Cabling Guide.
-
On the second controller, connect the power cables into power supply 0 and
power supply 1. Then connect each cable to the external power source.
The second controller powers on automatically.
-
Connect the second controller to the disk shelves.
See the documentation that came with your appliance or refer to Getting Started with Cabling in Oracle ZFS Storage Appliance Cabling Guide .
- On the standalone controller, go to Configuration > Cluster.
-
Confirm that the communication links between the two controllers are connected
and active.
If three solid lines are not shown, ensure that the three cluster cables are properly connected and secure in their connectors.
- Click SETUP.
-
Enter the host name for the second controller and the same root password that
is set on the first controller.
Note - An initial cluster configuration setup can take several minutes to complete. -
On the standalone controller, go to Configuration > Cluster and click the lock
icon
for the management interface.
Locking the management interface to the controller will prevent a transfer of resources when a failback occurs.
-
From the standalone controller, configure the management interface for the
second controller.
-
Go to Configuration > Network and click the add icon
next to Interfaces.
- Enter a name for the management interface, and check the boxes for Enable Interface and Allow Administration.
- Select an IP address and click APPLY.
-
Go to Configuration > Network and click the add icon
-
Go to Configuration > Cluster and click FAILBACK to bring the cluster to
Active:Active mode.
The two controllers are now configured as clustered peers.
-
On the second controller, go to Configuration > Cluster and click the lock
icon
for the management interface.
