Introduction
============
The Solaris port of sg3_utils contains those utilities that are _not_
specific to Linux. In some cases a utility could be ported but
requires more work. An example is sg_dd which needs more work
beyond the SCSI command pass through mechanism.

Supported Utilities
===================
Here is a list of utilities that have been ported:
    sg_format
    sg_get_config
    sg_ident
    sg_inq          [dropped ATA IDENTIFY DEVICE capability]
    sg_logs
    sg_luns
    sg_modes
    sg_persist
    sg_opcodes
    sg_prevent
    sg_raw
    sg_rdac
    sg_read_buffer
    sg_read_long
    sg_readcap
    sg_reassign
    sg_requests
    sg_rmsn
    sg_rtpg
    sg_safte
    sg_sat_identify
    sg_sat_phy_event
    sg_sat_set_features
    sg_senddiag
    sg_ses
    sg_start
    sg_stpg
    sg_sync
    sg_turs
    sg_verify
    sg_vpd
    sg_wr_mode
    sg_write_buffer
    sg_write_long

Most utility names are indicative of the main SCSI command
that they execute.  Some utilities are slightly higher level, for
example sg_ses fetches SCSI Enclosure Services (SES) status pages and
can send control pages. Each utility has a man page (placed in
section 8). An overview of sg3_utils can be found at:
http://www.torque.net/sg/sg3_utils.html .
A copy of the "sg3_utils.html" file is in the "doc" subdirectory.


See the INSTALL file (at the end) for instructions on how to build
sg3_utils on FreeBSD. Some man pages have examples which use linux
device names which hopefully will not confuse the FreeBSD users.


Details
=======
The ported utilities listed above, all use SCSI command functions
declared in sg_cmds_basic.h and sg_cmds_extra.h . Those SCSI command
functions are implemented in the corresponding ".c" files. The ".c"
files pass SCSI commands to the host operating system via
an interface declared in sg_pt.h . There are currently four
implementations of that interface depending on the host operating
system:
  - sg_pt_linux.c
  - sg_pt_freebsd.c
  - sg_pt_osf1.c  [Tru64]
  - sg_pt_solaris.c
  - sg_pt_win32.c

The sg_pt_solaris.c file uses the "uscsi" SCSI pass through
mechanism.

See the Solaris section in the INSTALL file for install directions.
