Test LAN Failover of Administrative
Cluster Traffic
Use the following procedure to test the LAN administrative traffic
failover capability of HP Clustered File System:
1. Connect your cluster servers with at least two physically separate
LANs. Configure the Linux network software to enable the interfaces
to these networks on each of the cluster servers.
2. From the HP CFS Management Console, log into one of the cluster
servers.
3. Observe on the Management Console which of your LANs is
currently being used for cluster administrative traffic. Physically
disconnect one of the server's LAN connections to this network.
4. Observe on the Management Console that HP Clustered File System
has noticed the network disconnection and has failed over the
administrative cluster traffic to one of the other LANs.
5. Reconnect the disconnected server to the LAN. Observe on the
Management Console that HP Clustered File System has noticed that
network connectivity has been restored for this LAN.
