You should control access to EDGINERS because it can overwrite previously labeled tapes regardless of expiration date and security protection. DFSMSrmm helps you prevent unauthorized users from using EDGINERS by using the RACF security resource STGADMIN.EDG.OPERATOR. Only users with access to STGADMIN.EDG.OPERATOR can use EDGINERS.

For more information about using STGADMIN.EDG.OPERATOR, see Authorizing DFSMSrmm users and ensuring security.
