Normally, a BCS is recovered separately from a VVDS. A VVDS usually does not need to be recovered, even if an associated BCS is recovered. However, if you need to recover a VVDS, and a BCS resides on the VVDS's volume, you must recover the BCS as well. If possible, you should export the BCS before recovering the volume, and then recover the BCS from the exported copy. This ensures a current BCS.

Before recovering a BCS or VVDS, try to recover damaged records. If damaged records can be rebuilt, you can avoid a full recovery. BCS records can be recovered using access method services DELETE and DEFINE commands with appropriate parameters. VVDS and VTOC records can be recovered using the DELETE command and by recovering the data sets on the volume. See Updating the Catalog After Recovery for more information on recovering individual entries.
