SYS1.VVDS.Vvolser not cataloged in MASTER catalog

Question & Answer


Question

The Manual DFSMS: Managing catalogs states that all SYS1 data sets must be cataloged in the MASTER catalog.

Answer

Description:

The manual DFSMS: Managing catalogs states that all SYS1 data sets must be cataloged
in the MASTER catalog.

Resolution:

As of DFSMS 1.1.0 (OS/390 1.1) SYS1.VVDS entries are no longer required to be
in the MASTER catalog.

SYS1.VVDS entries will still at times be seen in the MASTER catalog for volumes on which some user catalogs reside. This is caused by the catalogs being created under previous levels of DFP. Also if a data set resides on the same volume as a user catalog and the data set is, or once was, cataloged in the MASTER catalog, then a SYS1.VVDS entry will be in the MASTER catalog.

Also, when a VVDS is created, it does not have to be cataloged in any catalog, although the user can catalog it if they want.
