sg_raw [-r len] [-s len] [-i file] [options] device cdb

sg_raw sends arbitrary SCSI command descriptor blocks (CDBs) to a device and displays the response. It provides the lowest level of access to SCSI devices, allowing direct transmission of any command without interpretation or validation by the utility itself.
The tool supports all SCSI data transfer phases: commands that read data from the device (-r), commands that write data to the device (-s with -i), and commands with no data transfer. Response data can be displayed in hexadecimal, saved to a file, or output in binary format for further processing.
As part of the sg3_utils package, sgraw is primarily used for device testing, debugging SCSI protocol issues, and sending vendor-specific commands that are not covered by the higher-level sg3utils utilities.
