Remove Data Sets from VMS Control

When a data set no longer needs to be vaulted and the volumes currently controlled by VMS are returned to the library, follow these steps to remove the data set from VMS control:

Redefine Associated DSN Entries

• Add the keyword REDEFINED to the DSN= control statement.
• Change the V= control statement associated with the DSN= control statement to reflect V=LIB,EXP. (You may need to use a new V= statement if other DSNs that are associated with it are not to be REDEFINED; this prevents invalid movement.) Another method is to use V=vltx,CR=1; as long as there are no creations of the data set on the same day that VMS runs, all volumes are returned to the library with an OUTCODE of (blank)VMS.

Note: Removal of a DSN= entry from the pattern does not direct VMS to return the tapes to the library immediately. The tapes remain in the VMS location until expired, at which time they are returned to the library.

Execute VMS Job with PARM=TEST for TMSVMUPD

The VMS job should be executed using PARM=TEST on TMSVMUPD JCL to suppress updating of the TMC. Review the CA Earl reports to determine if the movement is correct.

Execute VMS Job

When you are satisfied with the results of the CA Earl reports, remove PARM=TEST from the TMSVMUPD JCL; the next execution of the VMS job establishes the new pattern. The DSN= control statement can then be removed from the VPD.
