This task must be done regularly to keep your Integrity servers up-to-date and secure. With clustered systems, you can do maintenance even when users are online. Wait until a convenient, off-peak time when one of the nodes in the cluster can be taken offline for maintenance and its workload distributed among the remaining nodes. Before the upgrade, however, you must evaluate the entire cluster to verify that the remaining nodes can handle the increased workload. Pick the node you want to upgrade, then use the Failover Cluster Management tool to move all the Services and Applications onto one or more of the remaining nodes. You can also use scripts to move resources. Once all the resources have been failed over to the other nodes, the selected node is ready to upgrade. For more information about how to upgrade your Integrity servers with the latest drivers and hot fixes, see the latest Smart Setup Guide for Integrity servers at: http://docs.hp.com/en/hw.html#Windows%2064-bit%20on%20HP%20Integrity%20Servers Once the upgrade to the first node is complete, reboot it if necessary and move the resources back to it. As soon as possible, repeat this process to upgrade the other nodes in the cluster. This minimizes the amount of time the nodes are operating with different versions of software or drivers. Evicting a Node from the Cluster To evict a node from the cluster, complete the following steps: 1. Click Start→Programs→Administrative Tools→Failover Cluster Management to run the Failover Cluster Management tool. 30 Installing and Configuring the Cluster
