Enable PostScan
PostScanisenabledbyselectingoneormoretriggercriteriawhenyou
configureapartition(see
EnableandConfigureMLMPreScanand
PostScanonpage199).TheavailablePostScanoptionsdependonthedrive
typeandwhetherornotaGlobalSparedriveisassignedtothepartition.

Configuration
WhenusingautomaticPostScantocheckyourcartridges,configureyour
storagemanagementsoftwaretoallowatleast15minutesforarequestedmove
tocomplete.Ifacartridgeisintheprocessofbeingscannedwhenitis
requestedforabackuporrestoreoperation,itmustbeunloadedfromthe

Globalspareandmovedtoanotherdrivebeforethemoverequestisreported
ascomplete.
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partit ions,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

Cleaning Partitions ThePostScanfeaturecannotbeenabledforacleaningpartitionanddoesnot
