theHPI‐B0101‐MIBmodule.OneofthesescalarobjectsisthesaHpiDiscover.0variable,which
initiallyreturnsthevaluetrue(1).

thistaskiscompleted,theHPIsubagentchangesthevalueofthesaHpiDiscover.0variable
fromtrue(1)tofalse(2).
ThesaHpiDiscover.0variablecanalsobesettotrue(1)toinitiateanewHPIdiscovery
