System Setup and Configuration for SuSE Linux Enterprise Server 7.1 Validating the LifeKeeper Cluster Configuration After the systems are configured and the resource hierarchy tree is functional from within LifeKeeper, system failover should be tested. To test failover: 1. Run the LifeKeeper console GUI on server node B. The console screen shows server node A as active and server node B in standby. 2. Right-click server node B and select In Service. A window displays as the scripts are run to switch server node B into service as the active system. 3. After server node B is active, right-click server node A and select In Service. Again, a window displays as the scripts run to make server node A active. 4. After server node A is active, turn off the power to server node A. This initiates a failure and server node B should become active. There will be a slight pause before server node B takes over. This is normal because it takes a few seconds for server node B to see that the heartbeat signal for server node A is gone. Configuration is now complete. IMPORTANT: If the packaged cluster is being transferred, return to "Setup in the Configuration Fixture" in Chapter 2 or refer to the packaged cluster hardware installation and configuration poster to complete the process.

Validating the LifeKeeper Cluster Configuration
After the systems are configured and the resource hierarchy tree is functional from
within LifeKeeper, system failover should be tested. To test failover:
1.
Run the LifeKeeper console GUI on server node B. The console screen shows
server node A as active and server node B in standby.
2.
Right-click
server
node B
and select
In Service.
A window displays as the
scripts are run to switch server node B into service as the active system.
3.
After server node B is active, right-click
server node A
and select
In Service.
Again, a window displays as the scripts run to make server node A active.
4.
After server node A is active, turn off the power to server node A. This initiates a
failure and server node B should become active.
There will be a slight pause before server node B takes over. This is normal
because it takes a few seconds for server node B to see that the heartbeat signal
for server node A is gone.
Configuration is now complete.
IMPORTANT:
If the packaged cluster is being transferred, return to “Setup in the
Configuration Fixture” in Chapter 2 or refer to the packaged cluster hardware installation and
configuration poster to complete the process.
