Recovering a Failed Primary Controller
Once you fail over to the Secondary controller, you can continue operating normally.
Both system controllers are identical in network and system management capabilities.
However, to recover the failed unit, you may have to replace or service the controller,
and then restart it. Once you've recovered the failed controller, you need to initiate a
Sync (synchronization) to ensure configuration data is up to date on both units.
Note: If you don't sync the system controllers, the recovered Primary controller may
push out-of-date configuration data to the host and remotes. Any configuration changes
you made while the failed controller was offline will be lost.
To recover a Primary controller after a failover:
1. Disconnect the failed system controller from the network.
2. Replace or service the unit, and then restart it by plugging in the AC cable into an
AC power source. There is no power switch. The controller starts up as Primary, but
is offline because it is disconnected from the network.
3. Log into the offline Primary controller.
4. Select the system controller in the tree, and display the Unit information view
.
5. Click the Failover Status button to toggle the unit to
Secondary
