Enable PostScan
PostScanisenabledbyselectingoneofthePostScanoptionsandoneor
morescantriggerswhenyouconfigureapartition(seeEnableand
ConfigureMLMPreScanandPostScanonpage177).Theavailable
PostScanoptionsdependonwhichgenerationofdrivesareinthepartition
andwhetherornotaGlobalSparedriveisassignedtothepartition.
Schedule a Manual PostScan
TheautomaticPostScantriggersonlyaddMLM‐enabledLTOdata
cartridgestothePostScanqueue.However,cartridgescanalsobeaddedto
thePostScanqueuemanually.Thisisespeciallyusefulifyourlibrary
containsLTOcartridgesthatarenotMLM‐enabled.Youcanalsousethe
manualPostScanprocesstoverifyasuspectMLM‐enabledcartridgeeven
ifitwaspreviouslyscanned.
CartridgesthataremanuallyaddedtothePostScanqueueareprocessed
beforecartridgesthatwereaddedasaresultofthetriggercriteriaforthe
partition.TheyareprocessedusingthePostScanoptionthatwasspecified
forthepartition.
Global Spare Drives BothFullScanandQuickScanusing GlobalSparerequireaGlobalSparedrive.
AlthoughaGlobalSparedrivecanbesharedbymultiplepartition s,assigninga
separateGlobalSparedrivetoeachpartitionisrecommended.Eachpartition
canthe nperformPostScanwhenevertheprerequisitesaremet,withoutwaiting
forPostScaninanother
partitiontocomplete.
Blackout Periods Becausethestoragemanagementsoftwarecanpotentiallyrequestatapethatis
currentlyundergoingverification,youcanconfigureblackoutperiodsduring
whichthePostScanoperationissuspended.Configuringblackoutperiods
ensuresthatPostScandoesnotoperateduringyournormalbackupwindow.
Theblackoutperiodsapplytoallofthestoragepartitions
inthelibrary.See
ConfigurePostScanBlackoutPeriodsonpage239forinstructions.
Cleaning Partitions ThePostScanfeaturecannotbeenabledforacleaningpartitionanddoesnot
