# 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).

This package is known to build and work properly using an LFS 12.2 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.
