User Guide
Track exported cartridges. When a cartridge is exported from the
library, an asterisk (*) next to the bar code indicates that it is
currently out of the library. However, all of the MLM data for the
cartridge is still available. Define the frequency with which you will
export the complete MLM report and make a note of all exported
tapes.
Only use your MLM-capable media and cleaning cartridges in MLM-
compatible libraries and tape drives. For the most accurate tracking,
do not load your MLM-capable media into non-Spectra Logic libraries
or drive generations lower than LTO-4. The memory chip in the
cartridge will not be updated with information about usage in those
locations and the information will not be recorded in the MLM
database when the cartridge is returned to your library.
Choose relevant information for saved reports. When you save an
MLM report (see Generating Media Lifecycle Management Reports on
page 155), you can choose between saving all MLM data or selected
data. The data is saved as comma delimited format for export into any
spreadsheet software.
Use only Spectra certified MLM-media and cleaning cartridges in a
partition. The library uses information in the MLM database to
determine remaining capacity. If the partition contains non-MLM, the
usable capacity shown will only represent that available on the MLM-
media. In addition, you cannot track non-MLM media in the MLM
database, determine if the media is past its useful threshold, or
determine if a particular piece of non-MLM media is experiencing high
errors rates or retries.
The library also tracks the number of uses for MLM-cleaning cartridges
and alerts you when a cleaning cartridge is nearing the end of it's 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.
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.
