8.15. SG_SCSI_RESET

SG_SCSI_RESET 0x2284. Assumes 3rd argument points to an int. That int should be one of the following defined in the sg.h header:

The reset options are in ascending order of severity. Not all levels are supported by all linux lower level drivers. Most lower level (adapter) drivers support the SCSI bus reset. These boards often issue a SCSI bus reset during their initialization.

Unfortunately this ioctl() doesn't currently do much (but may in the future after other issues are resolved). Yields an EBUSY error if the SCSI bus or the associated device is being reset when this ioctl() is called, otherwise returns 0. N.B. In some recent distributions there is a patch to the SCSI mid level code that activates this ioctl. Check your distribution.
