sd
Pointer to a scsi_device(9S) structure describing the
target.
waitfunc
NULL_FUNC or SLEEP_FUNC.
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.
See scsi_probe(9F) for the return values from scsi_hba_probe().
scsi_hba_probe() should only be called from the HBA's
tran_tgt_probe(9E) entry point.

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.
