Delete MLM Records From the Database

When the maximum number of records for the MLM database is reached,
the record for the least recently exported cartridge, as determined by the
Export Date tracked by MLM, is automatically deleted. The library does
not notify you when it reaches the maximum number of records.
When a tape is retired or permanently exported from the library, you can
manually delete its record from the MLM database. Records can be deleted
individually or as a group.

Follow these steps...
1. Plug the USB device into a PC. The PC does not need to be connected to the
library.
2. Examine the list of files on the USB device and locate the SavedMLMDB
folder.
3. Open the folder to verify that it contains the following file, where <date-
time> is the time stamp for when the backup was created:
 x mlinfo<date-time>.db
— OR —
 Zipped file — c minfo_<date-time>.zdt
4. Verify that the file is more than 0 bytes in size.
5. If a file with the correct filename format is present and is more than 0 bytes in
size, the database backup was successful and the file is usable. Store the USB
device in a safe location.
6. If the MLM database file is not present or if it is 0 bytes in size, repeat the
backup process (Back Up the MLM and DLM Databases on page 284) using a
different USB device.
1. Open the email attachment and verify that:
 The attachment contains a zip file called
cminfo_<date-time>.zdt
— AND —
 The file is more than 0 bytes in size.
2. If the zip file is present and is more than 0 bytes in size, the backup was
successful and is usable. Save the email attachment to a safe location from
which you can copy it to a USB device, if needed.
3. If the zip file is not present or if it is 0 bytes in size, repeat the backup process
(Back Up the MLM and DLM Databases on page 284) to generate the email
again.
