# ata\_scsi\_queuecmd(9)

Issue SCSI cdb to libata-managed device

## NAME

ata\_scsi\_queuecmd - Issue SCSI cdb to libata-managed device

## SYNOPSIS

**int ata\_scsi\_queuecmd(struct Scsi\_Host \*** *shost***, struct scsi\_cmnd \*** *cmd***);**

## ARGUMENTS

*shost*

SCSI host of command to be sent

*cmd*

SCSI command to be sent

## DESCRIPTION

In some cases, this function translates SCSI commands into ATA taskfiles, and queues the taskfiles to be sent to hardware. In other cases, this function simulates a SCSI device by evaluating and responding to certain SCSI commands. This creates the overall effect of ATA and ATAPI devices appearing as SCSI devices.

LOCKING: ATA host lock

## RETURN

Return value from **\_\_ata\_scsi\_queuecmd** if *cmd* can be queued, 0 otherwise.
