When a VSAM cluster is archived and recataloged to the CA Disk pseudo-volume, alias entries are also defined for each of the alternate index and path names, as well as for each of the components' names for the cluster. This enables the auto- restore function to be invoked when you reference the base cluster, any of its components, an alternate index, or path name associated with the base cluster.
Restore processing removes the catalog entry to the pseudo- volume and all of the aliases associated with it, and redefines the correct VSAM catalog entries. Should the restore process fail, CA Disk attempts to re-create the initial status by recataloging the cluster to the pseudo-volume and associating the proper alias names to it.
