Deleting a tape library definition removes the definition for that tape library from the specified SCDS and, upon activation of that SCDS, the tape library data server is unavailable to the system. Deleting a tape library dataserver has no effect on the TCDB because there may be other SCDSs that still contain the tape library data server. In order to delete a tape library from the TCDB, IDCAMS with the DELETE LIBENTRY parameters must be used.

As part of the tape library definition deletion, all storage group constructs in the SCDS that are defined as including the library undergoing deletion are updated to remove that library from the storage group definition. When the last library is deleted from a tape storage group, the invalid tape storage group definition remains in the SCDS. The SCDS will not validate until all invalid tape storage group definitions are either deleted or altered so that they contain at least one tape library.

From the Tape Library List panel (see Figure 1 through Figure 7):

1. Enter DELETE in the LINE OPERATOR column next to the tape library you wish to delete.
2. Press ENTER.

   The Confirm Delete Request panel, Figure 1, is displayed.
