HPI subagent initialization

WhentheHPIsubagentisstarted,initiallyyouwillseejustthestaticscalarobjectsdefinedin

theHPI‐B0101‐MIBmodule.OneofthesescalarobjectsisthesaHpiDiscover.0variable,which

initiallyreturnsthevaluetrue(1).

OncetheHPIserverisrunning,theHPIsubagentopensanHPIsessiontoitandstartsto

dynamicallypopulateallofthecolumnsandrowsintheHPI‐B0101‐MIBmoduletables.When

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

operation.Whentheoperationcompletes,theHPIsubagentre‐populatesitstablesand

changesthevalueofthesaHpiDiscover.0variablefromtrue(1)tofalse(2).

tableswhilethesaHpiDiscover.0variablehasthevaluetrue(1),becausetheHPIsubagentis
