Erase Sensitive Data

CA 1 provides the following utilities to erase sensitive data left over from the prior use of a tape:

CTSDEU: This utility erases media types that employ servo tracks and that cannot be bulk erased. CTSDEU erases residual data after new data has been written to the tape. CTSDEU positions to the end of the active data on the volume and performs security erase processing until the end of the physical volume. While positioning to the end of the volume, CTSDEU verifies that the files on the volume match the information saved in the CA 1 TMC.
TMSTPPRO: This utility erases tapes containing sensitive data, once the volume is in scratch status. Set the CA 1 system option DSEALL to force all scratch tapes to be erased before they are allowed to be used again. An exit is available to control the processing of the tapes.

The online ERASE command can be used to indicate that degauss processing has been performed for a volume.
