LTO Drives

From TechPubs Wiki

LTO drives, also called Ultrium drives, are magnetic Tape Drives backup drives that can store larger amounts of data than DDS Tape 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.
