6. Within several seconds, Cluster Administrator running on the surviving server
brings online all of the predefined resources and groups that were previously
owned by the powered-down server. If, after a minute, nothing seems to have
happened, press the F5 key to refresh the screen.
Verifying Network Client Failover
After you have verified that each server node is running correctly as a part of the
cluster, verify that network clients can interact with the cluster.
To validate the cluster:
1. Ensure that both servers are running, and use Cluster Administrator to verify that
all groups and resources are online.
2. For each hard drive in the storage system, Cluster Server automatically creates a
cluster group that consists of a single resource, the hard drive. Using Cluster
Administrator, add an IP address as another resource to one of these groups. (Do
not use the Cluster Group.)
3. Save the changes and return to the main Cluster Administrator screen.
4. Open an MS-DOS window on a network client machine.
5. Ensure that the network client can access the IP address added in step 2. From the
network client, execute a PING command using the cluster IP address as the
argument.
NOTE: Regardless of whether you are using WINS or DHCP, you can execute the
MS-DOS command PING to check the connection.
— If client access to the cluster resource is successful, the response displayed is:
Reply from IP Address: bytes=xx time=xxxms TTL=xx
— If the client could not access the cluster resource, the destination host is
reported as unreachable.
6. If the PING command is successful, use Cluster Administrator to perform a
manual failover of the cluster group that contains the IP address.
7. When the manual failover is complete, execute the PING command again.
