a. LTO-2 drives do not reformat LTO-1 cartridges. The drives will write to the cartridges in the LTO-1 format (100 GB
capacity).
b. LTO-3 drives read LTO-1; they do not write to the LTO-1 cartridges.
c. LTO-3 drives do not reformat LTO-2 cartridges to contain the same density as the LTO-3 cartridges (400 GB). The
LTO-3 drives will write to the LTO-2 cartridges in the LTO-2 format (200 GB capacity).
d. LTO-3 WORM requires the installation of library firmware and WORM-supported LTO-3 tape drive code.
All LTO cartridges are the same size, which means they use the same magazines in the library.
LTO drives can be directly attached to hosts, attached to the SAN, or connected to FC I/O blades in the
I/O management unit. SCSI drives must be directly attached to hosts or to the SAN.
