When you need to perform routine maintenance or other tasks on a LifeKeeper Server, you can use the LifeKeeper GUI to move in-service resources to another server. To transfer in-service resource hierarchies from Server A to Server B, use the GUI to bring the hierarchies into service on Server B. Repeat until all of Server A’s resources have been placed in-service on their respective backup servers. See Bringing a Resource In Service for instructions.
When all of Server A’s resources are active on their backup server(s), you can shut down Server A without affecting application processing. For the maintenance period, however, the resources may not have LifeKeeper protection depending on the number of servers in the cluster.
Thanks for your feedback.
