You can scratch tape volumes with either the CA 1 TMSCLEAN program or by an online SCRATCH command.
TMSCLEAN can optionally enforce SMS Management Class maximum retention specifications. Any tape data set found with an expiration date exceeding the SMS Management Class retention is scheduled for SCRATCH processing the following day.
TMSCLEAN determines which of the tapes held by Days Since Last Used Control and Catalog Days Control are to become eligible for scratch or reset to Catalog Control. If the CA 1 system option OCTLG is set to NO, TMSCLEAN process data sets under Catalog Control.
