When clusters are restored using the NEWNAME parameter, CA Disk must determine the new name to use for the data and index components. If AMS originally generated the name, CA Disk will allow VSAM to generate the new name for the component. However, if the user specified the component name at define time, CA Disk must generate a new name based on changes detected between the original base cluster name and the new name specified for the base cluster. In addition, the VSNEWNEX user exit is available to either specify a new component name or to instruct AMS to generate a new name. You can also assign new names on the RESTORE command via the DNAME and INAME parameters.
