If you specified DISPLAY in the EXPIREBV command, DFSMShsm allocates and opens the output data set for the expire backup listing. DFSMShsm uses the OUTDATASET | SYSOUT parameter that you specified in the EXPIREBV command to allocate the data set. If an error occurs in allocating or opening the output data set, DFSMShsm issues a message, and EXPIREBV processing ends.
