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 disks CLXWEB uses are in the PAIR state:
#export HORCMINST=101 #pairdisplay –fcx –g clxwebvgs
b. Move the service CLXWEB to Host3. Verify that service has successfully moved and started
on Host3:
#clusvcadm -r CLXWEB -m Host3
#clustat -s CLXWEB
c. Verify that the disk pairs are now in read/write mode on the remote storage system:
#pairdisplay –fcx –g clxwebvgs
d. After verifying that the service CLXWEB, including P9000 Cluster Extension, can be run
on each system in the cluster, move the service back to its primary system:
#clusvcadm -r CLXWEB -m Host1
#clustat -s CLXWEB
#pairdisplay –fcx –g clxwebvgs
Managing P9000 Cluster Extension services (RHCS)
This section includes the instructions for starting or stopping an RHCS service.
Starting an RHCS service

Configuring P9000 Cluster Extension with SLE HA
P9000 Cluster Extension Software is integrated with SLE HA using a configuration file and a custom
resource agent.
The executable clxxplxcs is called by P9000 Cluster Extension before volume group activation.
This checks the status of a device/copy group configured for use with an SLE HA agent. If necessary,
P9000 Cluster Extension takes appropriate actions to allow access to the volume group's physical
disks before attempting to activate and mount the logical volume on a cluster node.
