The library also tracks the number of uses for MLM-cleaning cartridges 
and alerts you when a cleaning cartridge is nearing the end of its useful 
life. With MLM-capable cleaning cartridges, usage information is 
retained even when the cleaning cartridge is exported from the library. 
With non-MLM cleaning cartridges, the library’s record of whether a 
cleaning cartridge is good or expired is lost when the cartridge is 
exported from the library. 
ƒ Always operate the library with Media Lifecycle Management 
enabled. If you disable and then re-enable Media Lifecycle 
Management, any loads, reads, writes, errors, and any other tape 
related events that occur while MLM is disabled are not recorded in the 
MLM database. 
ƒ Regularly back up your MLM database. Determine how frequently to 
export the MLM database to a USB key for storage. The database can be 
loaded back into the library from the USB key in the event of an error. 
See 
 for detailed information.
Note:
Backing up the MLM database produces a point-in-time 
snapshot of the MLM database. Based on the number of tapes 
you routinely import into and export from the library, determine 
how frequently backups are needed to ensure that you can easily 
restore the MLM database.
Using Media Lifecycle Management
After you enable Media Lifecycle Management (see 
Logic Certified MLM media and cleaning cartridges into the library, 
BlueScale MLM writes the cartridge bar code information and other 
information about the library to the cartridge’s memory chip and to the 
library’s MLM database the first time the cartridge is loaded and then 
unloaded from a drive. You can then use BlueScale MLM to monitor the 
health of the cartridges and generate a variety reports. If desired, you can 
save the reports to a USB key or email them to a previously configured 
mail user.
Note:
Until a cartridge is loaded into a tape drive in the library the first 
time, it does not appear on the Media Lifecycle Management 
reports. 
If a new cartridge is write-protected when it is inserted into a 
drive, the library cannot update the information on the 
cartridge’s memory chip.
