DFSMShsm maintenance commands are submitted primarily by a DFSMShsm-authorized system programmer who uses the HSENDCMD command to issue these commands from a TSO session. They can also be submitted by a system operator from the system console.

For descriptions of other DFSMShsm commands, see z/OS DFSMShsm Storage Administration.

For descriptions of the DFSMShsm control data set records, see z/OS DFSMShsm Data Areas, which is available online at the z/OS Internet Library at http://www.ibm.com/systems/z/os/zos/bkserv/.
