Tape Label Display (option 4.8)

If a tape is labeled (or if you want to find out if it is labeled) use Tape Label Display (option 4.8) to print the tape labels. This lets you determine the volume serial number of the tape, or determine which data sets are on the tape.

When you select Tape Label Display (option 4.8), the Tape Label Display panel shown in Figure 1 is displayed.

You can use Tape Label Display even if you do not have access to the data on the tape, because only the tape labels are read. To mount and process tapes with unknown volsers and labels, the Tape Label Display turns on BLP internally. If your installation does not allow BLP usage but Z Data Tools is running APF-authorized, Z Data Tools forces BLP for this function; for security reasons, the tape is freed (unallocated) when Tape Label Display ends.

Figure 2 shows an example of the default output from Tape Label Display. You can also request a shorter report that lists only the VOL1 label and the header labels for the first data set.
