LTO7 Type M media
20 Dell EMC Tape Compatibility Matrix | Rev. A51
10 LTO7 Type M media
The LTO consortium approved a new media format to be used with LTO8 tape drive technologies. The new
LTO7 Type M media format allows an LTO8 drive within a supported Dell EMC library to format a new,
unused, LTO7 tape cartridge for 9 TB of native data capacity. The media designator for the LTO7 Type M
format is M8.
10.1 Using LTO7 Type M media in Dell EMC tape libraries
To use the LTO7 Type M format the LTO8 drive, library and tape cartridge must all meet minimum
requirements:
• Tape Drive must be at Firmware Revision HB8x or higher.
• Library Firmware must be at Firmware Revision:
- ML3–1.1.1.1-B00 or higher
- TL1000–0080.3000 or higher
- TL2000/TL4000–F.10/3.20e or higher
- ML6000 – 710G.GS007 or higher
• LTO7 tape cartridge:
- Uninitialized and unformatted to LTO7 Type M:
o Must have an M8 designated barcode.
o Must be new non-formatted tape cartridge.
- Initialized and formatted to LTO7 Type M:
o Must have an M8 designated barcode.
10.2 Using LTO7 Type M media in Dell EMC tape drives
Standalone LTO8 tape drives write or read to the 9TB format provided the drive is at firmware version of
HB8x or higher and the tape is already formatted with the LTO7 Type M format. Standalone tape drives do
not have a process to format uninitialized LTO7 media into the Type M format.
10.3 Formatting an LTO7 Type M tape in a Dell EMC library
To create Type M media from LTO7 tape cartridges in a Dell EMC tape library, users must only ensure that all
hardware and tape cartridges meet the requirements from section 10.1. The remaining steps are transparent
to the end user.
When a backup job begins, the backup application signals to the library to move a piece of media from a slot
to a drive. The library scans the barcode, picks the media, and signals to the drive the media type before
inserting it into the drive. The tape cartridge is initialized when it is first loaded into the drive and the backup
application writes data at the beginning of tape. This action is sometimes called "labeling a tape" or "writing
from BOT." The tape drive then establishes the density of the media. There must be a “Write from BOT”
before the media can be formatted to the 9 TB capacity. Loading a tape into the drive and ejecting does not
format the media.
