DuringthePreScanprocess,thelibraryautomaticallyinsertseach
cartridgeintoanavailableLTO‐4orlatergenerationdriveassignedtothe
partition.Thedriveloadsthecartridgeandchecksittodeterminewhether
ithasanyofthefollowingcharacteristics:
 Non‐MLM‐enabled
 Brokenordislodgedleader
 Redmediahealth
 Writeprotected
 Encryptedtapewithamonikernotcurrentlystoredinthelibrary
WhenthePreScanprocessiscomplete,thelibrarystoresthetapehealth
informationforthecartridgeintheMLMdatabase.ItalsowritestheMLM
datatothecartridgeMAM.Whenthedriveejectsthecartridge,thelibrary
returnsittoitsoriginalslot.
Requirements for Use InordertousePreScan,makesurethatthelibrary,
drives,anddatacartridgesmeetthefollowingrequirements:
Consideration Requirement
Drive Firmware  LTO‐4:requires97F9orlaterfirmware.
 LTO‐5:requiresB171orlaterfirmware.
 LTO‐6:supportedwithanyfirmware.
 LTO‐7:supportedwithanyfirmware.
Updating MLM
Data on MAM
UpdatingthecartridgeMAMrequiresthecartridgetobewrite‐enabled.
Important: If a cartridge is write-protected when it is inserted into a drive, the
information about the cartridge is added to the MLM database, but the library
cannot update the MLM information on the cartridge’s MAM.
Drive Availability Themediadiscoveryprocessloadsthecartridgesinthepartitionintothedrives
