Overview BlueScale Drive Lifecycle Management works in conjunction
with MLM to help you identify drives that experience a high number of
errors or other problems during operation.
Each time a cartridge is unloaded from a drive, the library collects the
media health data from the drive. This data includes read/write errors,
tape alerts, and flags generated during the time the most recent cartridge
was loaded in the drive. It also includes the current value for the drive's
single character display (SCD) and any errors detected at the time the
cartridge is unloaded. All of this data, plus the MLM data for the 50 most
recently loaded cartridges, is stored in the DLM database. This data is used
to generate an overall drive health status for the library, as well as health
reports for each individual drive.
Enabling DLM BlueScale Drive Lifecycle Management (DLM) is
automatically enabled when Media Lifecycle Management (MLM) is
enabled and cannot be used without MLM. See Chapter 9 – Configuring
and Using Media Lifecycle Management, beginning on page 245 for
detailed information about enabling and using MLM.
