Managing Serviceguard Sixteenth Edition, March 2009

• Fail one of the systems. For example, turn off the power on node 1. Make sure
the package starts up on node 2.
• Repeat failover from node2 back to node1.
2. Be sure to test all combinations of application load during the testing. Repeat the
failover processes under different application states such as heavy user load versus
no user load, batch jobs vs online transactions, etc.
3. Record timelines of the amount of time spent during the failover for each
application state. A sample timeline might be 45 seconds to reconfigure the cluster,
15 seconds to run fsck on the filesystems, 30 seconds to start the application and
3 minutes to recover the database.
