Verifying Node Failover
IMPORTANT: Do not run any client activity while testing failover events.
To verify failover of a cluster node:
1. From the desktop on both servers, select Start, Programs, Administrative
Tools (Common), Cluster Administrator.
2. When you are prompted for the Cluster Name or Server Name, enter the name
or IP address of the cluster.
3. Be sure that all cluster resources and cluster groups are online. Verify that some
of the cluster groups are owned by the server you will be powering off so that a
failure event will result in a failover of cluster groups.
4. Power off the server mentioned in step 3.
Within several seconds, Cluster Administrator running on the surviving node
should bring online all the predefined resources and groups that were previously
owned by the powered-off server. If, after a minute, nothing appears to have
occurred, refresh the screen by selecting Refresh (or by pressing the F5 key).
5. If failover is not working correctly, refer to the installation troubleshooting tips in
Chapter 6.
6. Power on the powered-off server to continue.
Verifying Network Client Failover
Now that you have verified that the server is correctly running as a cluster node, the
next step is to verify that network clients can interact with the cluster.
To verify network client failover:
1. Be sure that both cluster nodes are running and verify through Cluster
Administrator that all groups and resources are online.
