Configuring XP Cluster Extension with SLE HA
XP Cluster Extension Software is integrated with SLE HA using a configuration file and a custom
resource agent.
The executable clxxplxcs is called by XP Cluster Extension before volume group activation. This
checks the status of a device group configured for use with an SLE HA agent. If necessary, XP 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.

1. Create and configure an XP Cluster Extension resource. For instructions, see “Creating and
configuring an XP Cluster Extension resource” on page 102.
2. Configure the pair/resync monitor if you plan to use the pair/resync feature (optional). For
instructions, see “Configuring the pair/resync monitor” on page 108
