Testing the service configuration

The procedure and commands in this section are based the sample configuration in “HP HP 3PAR

Cluster Extension for Linux: Sample configuration” (page 48)

Use this procedure as a guide for configuring your environment.

1. Use the Cluster User Service Administration Utility (clusvcadm) to start the service on Host1.

#clusvcadm -e CLXWEB –m Host1

2. Verify that the service started successfully.

#clustat –s CLXWEB

3. Stop the service and verify that the service stopped successfully.

#clusvcadm –s CLXWEB Or #clusvcadm –d CLXWEB

4. Start the service on Host2.

#clusvcadm –e CLXWEB –m Host2

5. Relocate the service to a remote data center node.

a. Verify that the Remote Copy volume group is in destination mode on the remote HP 3PAR

storage system using the HP 3PAR Inform Management GUI or CLI.

For more information, see HP 3PAR Remote Copy User Guide.

b. Relocate the service using the cluster administration command.

#clusvcadm –r CLXWEB –m Host3
