Configuring EVA Cluster Extension with SLE HA
EVA Cluster Extension Software is integrated with SLE HA using a configuration file and a custom
resource agent.
The executable clxevalxcs is called by EVA Cluster Extension before volume group activation. This
checks the status of an EVA DR group associated with a volume group configured for use with an SLE
HA agent. If necessary, EVA 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.
Configuration overview
1. Configure the SMI-S server information and copy it to all of the cluster nodes. For instructions,
