To restore a VVDS or VTOCIX data set, you must specify the fully qualified data set name. The VVDS and the VTOCIX data set cannot be restored with other data sets in the same RESTORE command. VVDS and VTOCIX data sets should not be restored by data set as a normal recovery procedure. The VTOCIX data set is an extension of the VTOC and can be rebuilt using the Device Support Facilities program (ICKDSF) BUILDIX command.

The VVDS is an extension of the VTOC and of the catalogs for the VSAM data sets on the volume. If it is restored by a data set restore operation, it is possible that some of these data sets can become unusable because of a mismatch between the catalog, the VVDS, and the VTOC. If this occurs, run the diagnose function of access method services to determine the extent of the problem and to take appropriate corrective action.

DFSMSdss/VVDS Manager does not support dumping a multiple-extent VVDS and restoring the VVDS to a nonpreallocated VVDS. DFSMSdss can restore to a nonpreallocated VVDS only when the source VVDS resides on one extent.
