Explanation: ARECOVERPERCENTUTILIZED(nnn) is an optional parameter that allows you to change the percentage to which DFSMShsm allows DFSMSdss to fill non-SMS-managed DASD recovery volumes. For nnn, substitute an integer number between 1 and 100.
SMS relationship: Parameter does not apply to SMS-managed DASD volumes or data sets.
DFSMShsm default: If you do not specify this parameter on any SETSYS command, the DFSMShsm default is 80% (080).
