Utilities that send SCSI commands to Linux devices. Sg3_utils package contains utilities that send SCSI commands to Linux devices. And SCSI devices on the transport (eg, Fiber Channel and parallel SCSI interface) Many other devices use SCSI command sets.Examples ATAPI CD / DVD and SATA drives (usually via a translation layer or of a bridge device). SCSI command sets are divided into so-called "primary" commands (eg SPC-3) and device class specific sets (eg, SBC-2 drives and MMC-4 for devices CD / DVD). SCSI command sets and transports the definitions can be found at www.t10.org. Package sg3_utils target the Linux kernel 2.4 and 2.6 and is still under active development. A package called sg_utils previously targeted the Linux 2.2 kernel series with some support for the 2.0 series. See an earlier version of this web page for more information on sg_utils. This document describes version 1.18 of sg3_utils. In the Linux kernel 2.4 series over these utilities must be used with a controller SCSI Generic (sg) name of device driver (eg / dev/sg0). In the lk 2.6 series almost all of these utilities can be used with the device names and primary (eg / dev / sda, / dev/sdc0, / dev/st0 and / dev / hdd (if it is a device ATAPI)). The SCSI Generic (sg) interface is still cleaner interface than the primary device names, since the drivers behind the primary device names have their own policies, may interfere with the processing error and, in some cases conduct their own machines state.
