SCSI_HBA_PROBE(9F) Kernel Functions for Drivers SCSI_HBA_PROBE(9F)

NAME

scsi_hba_probe - default SCSI HBA probe function

SYNOPSIS

#include <sys/scsi/scsi.h>


int scsi_hba_probe(struct scsi_device *sd, int(*waitfunc)(void));

INTERFACE LEVEL

illumos architecture specific (illumos DDI).

PARAMETERS

sd
Pointer to a scsi_device(9S) structure describing the
target.


waitfunc
NULL_FUNC or SLEEP_FUNC.

DESCRIPTION

scsi_hba_probe() is a function providing the semantics of
scsi_probe(9F). An HBA driver may call scsi_hba_probe() from its
tran_tgt_probe(9E) entry point, to probe for the existence of a
target on the SCSI bus, or the HBA may set tran_tgt_probe(9E) to
point to scsi_hba_probe directly.

RETURN VALUES

See scsi_probe(9F) for the return values from scsi_hba_probe().

CONTEXT

scsi_hba_probe() should only be called from the HBA's
tran_tgt_probe(9E) entry point.

SEE ALSO
