Package: sg3-utils (1.21-1ubuntu1~dapper1) [universe]

Utilities for working with generic SCSI devices

This package includes a number of utilities to manipulate the linux "sg" (version 3) device driver.

This driver is only found in 2.4.x linux kernels; if you are using 2.2 (or earlier), please install the sg-utils package instead. In the 2.4 series SCSI generic device names (e.g. /dev/sg0) must be used. In the 2.6 series other device names may be used as well (e.g. /dev/sda).

The package includes:

    * sg_dd - a variant of 'dd' that works at the SCSI command level
    * sg_emc_trespass - vendor specific for Clariion hardware
    * sg_format - format SCSI disks
    * sg_get_config - get features and profiles of MMC devices
    * sg_ident - report and set device identifiers
    * sginfo - a re-porting of the 'scsiinfo' program, updated
    * sg_inq - a utility for poking around with the SCSI INQUIRY command
    * sg_logs - prints out log sense pages
    * sg_luns - prints out REPORT LUNS response
    * sg_map - shows the mapping between SCSI devices and sg devices
    * sg_map26 - utility to map sg devices in 2.6 kernel
    * sgm_dd - like sg_dd, but uses mmap()'d IO
    * sg_modes - prints out mode sense pages
    * sg_opcodes - reports supported opcodes and task management fcns
    * sgp_dd - like sg_dd, only multithreaded
    * sg_persist - accesses the Persistent Reservation In and Out commands
    * sg_prevent - issues PREVENT ALLOW MEDIUM REMOVAL command (MMC + SSC)
    * sg_rbuf - tests SCSI bus speed
    * sg_rdac - utility for vendor specific work
    * sg_read - reads multiple blocks, useful for timing
    * sg_read_long - read a "long" block from the given device
    * sg_readcap - prints the output of a READ CAPACITY command
    * sg_reassign - issues a REASSIGN BLOCKS command (map out bad sectors)
    * sg_requests - issues a REQUEST SENSE command (event polling)
    * sg_reset - exercises SCSI device/bus/host reset capability
    * sg_rmsn - READ SERIAL SERIAL NUMBER
    * sg_rtpg - REPORT TARGET PORT GROUPS
    * sg_scan - displays the SCSI bus on stdout
    * sg_senddiag - runs SCSI self tests
    * sg_ses - fetches status and send control to a SES device
    * sg_start - spins up (or down) disks and optical drives
    * sg_sync - issues a SYNCHRONIZE CACHE command
    * sg_test_rwbuf - tests the SCSI host adapter
    * sg_turs - execute a TEST UNIT READY command on the given device
    * sg_verify - issues VERIFY command on SCSI disks
    * sg_vpd - utility for decoding VPD pages
    * sg_write_long - write a "long" block to the given device
    * sg_wr_mode - low level utility to change mode pages

It also includes source code for some example programs that demonstrate how to use the scsi generic driver.
