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 File Manager
is running APF-authorized, File Manager 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.
