Example 1
An external volume with an internal standard label of 111111 is delivered to the data center. The tape librarian checks in the tape and finds that there is already an existing volume with this volser in the Media Database. A unique value, NEW111, is assigned to the volume and entered in the VOLSER field. The original volser value (111111) is entered in the SL-NAME field.
When the volume is requested for processing, the JCL statement includes the parameter VOL=SER=NEW111. The operator mounts volume NEW111. Normally, the operating system would reject the mounted volume since the internal label (111111) does not match the requested volser (NEW111). However, Control-M/Tape performs its own validation checking routine. Control-M/Tape determines that the value in the SL-NAME field (111111) matches the internal label of the mounted tape. Control-M/Tape forces the operating system to accept the volume for processing.
Example 2
Every Monday morning a tape is delivered from the social security office with the same physical standard label (SS0001). The tape librarian checks in the tape using the External Volume Check-In screen and an automatically generated volser, as shown in Figure 43.

A gummed label with the new logical volser (EXT045) is applied externally to the tape.
When online inquiries are made about the tape, the original volser (meaning, the SL-NAME) is entered in the Inquire/Update entry panel.
