#include <sys/scsi/scsi.h> int scsi_slave(struct scsi_device *devp, int (*callback)(void));
The scsi_slave() function is obsolete. This function has been replaced by scsi_probe(9F).
scsi_slave() checks for the presence of a SCSI device. Target drivers may use this function in their probe(9E) routines. scsi_slave() determines if the device is present by using a Test Unit Ready command followed by an Inquiry command. If scsi_slave() is successful, it will fill in the scsi_inquiry structure, which is the sd_inq member of the scsi_device(9S) structure, and return SCSI_PROBE_EXISTS. This information can be used to determine if the target driver has probed the correct SCSI device type. callback indicates what the allocator routines should do when DMA resources are not available:
scsi_slave() is normally called from the target driver's probe(9E) or attach(9E) routine. In any case, this routine should not be called from interrupt context, because it can sleep waiting for memory to be allocated.
