I am sponsoring this update to the previously approved sg3 utilities case
sg3 utilities 1.25 [PSARC/2008/683]. It times out 01/22/2009.
Here are the detailed changes from v1.25 to v1.26:
Features changed:
1) add a new command, sg_sat_phy_event
2) enhanced some of the existing commands(new options added, code refinement)
3) enriched existing manpages
Major changes for ARC case documents:
1) add a new interface(command sg_sat_phy_event)
2) modify an existing interface(private library and its symbolic link) name
libsgutils.so -> libsgutils2.so
libsgutils.so.1 -> libsgutils2.so.2
libsgutils.so.1.0.0 -> libsgutils2.so.2.0.0
3) add a new interface(manpage of sg_sat_phy_event)
The updated documents and a diff file are in the case directory

2. Project Summary
2.1. Project Description
This project updates the Sg3 utilities from 1.25 to 1.26.
4. Technical Description
The sg3_utils package contains utilities that send SCSI commands to
devices. As well as devices on transports traditionally associated
with SCSI (e.g. Fibre Channel (FCP), Serial Attached SCSI (SAS) and
the SCSI Parallel Interface(SPI)) and many other devices use SCSI
command sets. ATAPI cd/dvd drives and SATA disks that connect via a
translation layer or a bridge device are examples of devices that
use SCSI command sets.
There are about 33 command line utilities inside this package.
Command name Notes
============ ===================================================
sg_get_config fetch features and profiles of a cd/dvd drive and/or
its current media
sg_ident default is to report (fetch) the device identifier.
With the '--set' option a new identifier is sent to
the device.
sg_inq fetch standard response, VPD pages or version
descriptors. Also can perform IDENTIFY (PACKET)
DEVICE ATA command. VPD page decoding also performed
by sg_vpd and sdparm.
sg_logs fetch log sense pages, decode standard and some vendor
pages
sg_luns fetch luns reported by a device (lun 0 or "well known
lu")
sg_modes fetch mode pages (output mainly in hex, to decode
output use sdparm)
sg_opcodes fetch supported SCSI commands or supported task
management functions
sg_persist control persistent reservations and report reservation
status
sg_prevent control media removal, mainly for those SCSI devices
which have removable media (e.g. CD/DVD and tape drives)
sg_raw send user supplied cdb
sg_rdac display or modify RDAC redundant controller mode page
sg_read_buffer read descriptors or data
sg_read_long read data from given lba which includes the block and
ECC data.
sg_readcap fetch the number of blocks and the individual block
size for disks and CD/DVD media
sg_reassign reassign a lba from one sector on a disk (typically
damaged) to a new (spare) sector. User data copied if
it is recoverable.
sg_requests fetch sense data from the given device. Modern uses
include getting a progress indication (e.g. during a
format) or finding the power condition state.
sg_rmsn Relatively new command added to SPC-3. Format of
response is vendor specific so this utility outputs
it in hex (default) or binary.
sg_rtpg Specialized for multi-ported SCSI devices where one
port (or a group of them) is preferred for IO over
another (or others).
sg_safte fetch information from a SAF-TE processor.
sg_sat_identify Send ATA IDENTIFY DEVICE or IDENTIFY PACKET DEVICE
commands via the SAT ATA PASS-THROUGH (16 or 12) SCSI
command.
sg_sat_phy_event Sends an ATA READ LOG EXT command via a SAT to
fetch log page 11h which contains SATA phy event counters.
sg_sat_set_features Sends ATA SET FEATURES command via SAT.
sg_senddiag Issues either a default self test or a short/extended
foreground/background self test. With no arguments it
uses RECEIVE DIAGNOSTIC RESULTS to list all supported
diagnostic pages.
sg_ses Fetches status diagnostic pages from, and sends some
control pages to, a SCSI Enclosure Services (SES)
device.
sg_start Controls the power condition state of a SCSI device.
Primary use is to spin up and down SCSI disks. Can
also load and eject removable media.
sg_stpg Specialized for multi-ported SCSI devices where one
port (or a group of them) is preferred for IO over
another (or others).
sg_sync Causes disk caches to be flushed to media.
sg_turs Issue one or more Test Unit Ready commands. Can be
used to time SCSI command overhead.
sg_verify reads indicated blocks on a SCSI disks, stops on the
first error found. Does not yield any data. Useful
for media scans.
sg_vpd Decodes standard and some vendor Vital Product Data
(VPD) pages.
sg_wr_mode writes mode pages supplied in ASCII hex (e.g. from
"sg_modes -r") to the SCSI device. See sdparm for
another method of setting mode page parameters.
sg_write_buffer write data; can be used to download firmware.
sg_write_long writes to a lba, data which includes the block and
ECC data. Suitable data typically fetched by prior
sg_read_long utility.
