LABEL NL Option

Use the LABEL NL option to have CA VM:Tape use non-labeled processing. Non-labeled (NL) tapes have no internal labels.

When the tape is mounted, CA VM:Tape checks for a VOL1 label, then proceeds as follows:

• If CA VM:Tape does not find an internal label, CA VM:Tape prompts the tape operator for the volser on the external label. CA VM:Tape uses that volser to locate the information for the tape in the TMC.
• If CA VM:Tape finds an internal label, CA VM:Tape checks the LABEL configuration record and the Autopick Facility.
  • If either the LABEL record specifies label destruction or Autopick is active, CA VM:Tape destroys the label by writing a tape mark at the requested density.
  • If the LABEL record does not specify label destruction and Autopick is not active, CA VM:Tape unloads the tape and asks the operator to mount the correct tape.
