Important
The library must be using BlueScale12.0.3 or later and the drives must be using
firmware version B6W0 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 unload 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.
Important
When an LTO-5 drive is running a firmware version earlier than B6W0, 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, the MLM data for the cartridge is lost.
Important
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.
