ADR255E
(ttt)-mmmmm(yy), EXTENT starting_c:h-ending_c:h ON VOLUME volser COULD NOT BE ERASED USING A FAST ERASE METHOD

Explanation

DFSMSdss is unable to erase the source extent using a fast erase technique following successful relocation of the extent during DEFRAG or CONSOLIDATE processing. DFSMSdss does not attempt to erase the source extent using traditional I/O because FASTREPLICATION(REQUIRED) is specified. The extent is either part of an erase-on-scratch data set or the ADMINISTRATOR keyword is specified. This can potentially cause sensitive data to be left at the source location on the volume.

System action

DFSMSdss DEFRAG or CONSOLIDATE processing continues. The return code is 8.

Operator response

None.

Programmer response

See the previously issued ADR933W for an explanation of why the ANTRQST SRELEASE request failed. Specify FASTREPLICATION(PREFERRED) if you want DFSMSdss to always retry and erase the source extents using traditional I/O when the ANTRQST SRELEASE fails.

To alleviate the case where the sensitive data is left at the source location, the ICKDSF TRKFMT command can be used to erase the data left on the source location. See the Device Support Facilities (ICKDSF) User's Guide and Reference for more information.
