Explanation: PERCENTUTILIZED(nnn) is an optional parameter that allows DFSMSdss to fill the L0 volumes in the associated ARPOOL up to 100% (100) for this aggregate.
For nnn, substitute an integer between 1 and 100.
Defaults: If you do not specify a PERCENTUTILIZED value, the default value is specified by the SETSYS ARECOVERPERCENTUTILIZED parameter. The SETSYS ARECOVERPERCENTUTILIZED default value is 80% (080).
