Updating the MLM Database
When the PostScan process on a cartridge is complete, the library writes
the scan date and a pass/fail test result to the cartridge MAM and updates
the MLM database with the scan date, the pass/fail test result, and when
(or if) the next scan should occur. The drive then unloads the cartridge and
the library returns it to its original slot. The library then posts a system
message showing that the cartridge was scanned. If the QuickScan used a
partition drive, the library reports that the unload move for the backup
operation that preceded the QuickScan is complete.
Global Spare Drive Cleaning
After a cartridge is unloaded from a Global Spare drive following a
PostScan verification, the library checks to see if the drive requires
cleaning. If cleaning is required and a cleaning partition is associated with
the storage partition to which the Global Spare is assigned, the drive is
cleaned before the next cartridge is processed.

Note: If a cleaning partition is not present, periodically check the Drive
Details screen for each drive to determine whether cleaning is
required. If cleaning is required, follow the instructions
provided in Manually Cleaning a Drive on page 419.
Description
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.
 FullScan, QuickScan, and QuickScan using Global Spare are available for all
Fibre Channel LTO and TS11xx technology drives.
 Partitions using SAS drives cannot use FullScan or QuickScan using a Global
Spare drive.
Note: While a drive is in use for QuickScan operations, it is unavailable to the
storage management software.
To protect you from making changes that could negatively impact the libraryʹs
operation, the BlueScale software automatically prevents you from performing
certain operations while either a FullScan or a QuickScan that uses Global Spare
drives is running. However, you can pause the FullScan or QuickScan
operation if you cannot wait for it to complete. See Background Operations on
page 253 for detailed information.
