# sg3_utils-1.48

## Introduction to sg3_utils

The sg3_utils package contains low level utilities for devices that use a SCSI command set. Apart from SCSI parallel interface (SPI) devices, the SCSI command set is used by ATAPI devices (CD/DVDs and tapes), USB mass storage devices, Fibre Channel disks, IEEE 1394 storage devices (that use the "SBP" protocol), SAS, iSCSI and FCoE devices (amongst others).

### Note

This package is known to build and work properly using an LFS 13.0 platform.

## Installation of sg3_utils

Install sg3_utils by running the following commands:

    ./configure --prefix=/usr --disable-static &&
    make

This package does not come with a test suite.

Now, as the `root` user:

    make install

## Command Explanations

`--disable-static`: This switch prevents installation of static versions of the libraries.
