The configuration file defines the relation between the source and target volumes that need to be synchronized or verified. After you have created the configuration file make sure that it is available in the directory from where you intend to run the vxrclient or vxrserver command.
Each host system must have a configuration file that contains the following information:
A description of all host systems and the local host
Association of the volumes between each host system that is linked for synchronization
Association between the volumes on different host systems
To facilitate managing multiple volumes present on one or more hosts with ease, vxrclient associates one or more related volumes into an organizational construct that is called a group. A group is identified by its <group name>. You can use the concept of a group to synchronize a number of volumes in one operation.
