View source for LTO Drives


LTO drives, also called Ultrium drives, are magnetic tape backup drives that can store larger amounts of data than DAT/DDS drives can and are well-supported under IRIX.

=== Configuration ===
To configure an LTO drive requires a configuration to be placed in /var/sysgen/master.d/scsi.

=== Compatibility ===
Most documented cases include LTO1 through 4 drives. Others could potentially work but have not been tried.

=== Examples ===
