Need HSM support for LTO7 M8 media.

The LTO program introduced a new capability with LTO 8 tape drives: the ability to write 9 TB (native) on a brand new LTO Ultrium 7 cartridge instead of 6 TB (native) as specified by the LTO 7 format. Such a cartridge is called an LTO Ultrium 7 cartridge initialized as Type M media (M8). These cartridges are identifiable by using an automation barcode label ending with the characters M8.

Only new, unused LTO Ultrium 7 cartridges can be initialized as M8 cartridges. Once a cartridge is initialized as M8, it cannot be changed back to L7. Initialized M8 cartridges can only be written and read in an LTO 8 tape drive; LTO 7 tape drives cannot read initialized M8 cartridges.
