This package is a collection of tools for manipulating SCSI hardware:

scsiinfo: displays SCSI drive low-level information and modifies SCSI drive settings, scsidev: makes permanent SCSI LUN -> devicename connections, scsifmt: low-level SCSI formatter, sraw: benchmarks raw SCSI I/O rates bypassing the buffer cache, scsi-spin: program to manually spin up and down a SCSI device.

Beware that, to be used properly, these tools require some knowledge of what they're doing as they can cause damage to your system.
