Recovering a Tape: No Duplex Available

The following steps describe the actions you must take to recover a tape when no duplex is available.

1. Map the contents of the backup tape by using the SARTCP program.

   You might have to use bypass label processing (BLP) in the JCL to have SARTCP start at a point in the tape that is read-able.

2. Run SARTCP to copy the backup tape to a new tape.

   Use the SKIP control statements to bypass the unreadable portions of the input tape.

   Each SKIP statement must have a corresponding NULL statement to maintain proper positioning on the output tape.

3. Uncatalog the old (damaged) backup tape, and then catalog the new backup tape.

   To perform this processing, see Example 2, in the JCL.
