The library must be using BlueScale12.0.3 or later and the LTO-5 drives must be
using firmware version B6W1 or later in order to move the MLM data to the new
location on the cartridge MAM.
If you reformat LTO-5 data cartridges to use LTFS in a library using an earlier version
of the BlueScale software or if you reformat the cartridges before you load and
unloaded them from a drive to move the MLM data, the MLM data for the cartridge
is lost. The cartridges are subsequently treated as non-MLM-enabled.
When an LTO-5 drive is running a firmware version earlier than B6W1, it can only
access the MLM data at the old MAM location. The BlueScale software does not
attempt to move the MLM data; it continues to use the old location for the MLM data.
If the cartridge is reformatted to use LTFS without moving the data to the new
location, the MLM data for the cartridge is lost.
If the BlueScale software already moved the MLM data, the cartridge appears to be
non-MLM enabled when loaded into a drive that is using down-level firmware. The
MLM data is not updated.
To ensure full MLM tracking of your LTO-5 data cartridges, make sure that the
library is using BlueScale12.0.3 or later and that all LTO-5 drives are using firmware
version B6W1 or later.
