TRAN_TGT_PROBE 9E "Nov 1, 1993"
NAME
tran_tgt_probe - request to probe SCSI bus for a particular target
SYNOPSIS
#include <sys/scsi/scsi.h> int prefixtran_tgt_probe(struct scsi_device *sd, int (*waitfunc, void)););
INTERFACE LEVEL
illumos architecture specific (illumos DDI).
PARAMETERS
sd
Pointer to a scsi_device(9S) structure.
Pointer to either NULL_FUNC or SLEEP_FUNC.
DESCRIPTION
The tran_tgt_probe() vector in the scsi_hba_tran(9S) structure may
be initialized during the HBA driver's attach(9E) to point to a
function to be called by scsi_probe(9F) when called by a target driver
during probe(9E) and attach(9E) to probe for a particular SCSI
target on the bus. In the absence of an HBA-specific
tran_tgt_probe() function, the default scsi_probe(9F) behavior is
supplied by the function scsi_hba_probe(9F).
The possible choices the HBA driver may make are:
Initialize the tran_tgt_probe vector to point to scsi_hba_probe(9F), which results in the same behavior.
Initialize the tran_tgt_probe vector to point to a private function in the HBA, which may call scsi_hba_probe(9F) before or after any necessary processing, as long as all the defined scsi_probe(9F) semantics are preserved.
waitfunc indicates what tran_tgt_probe() should do when resources are not available: NULL_FUNC
Do not wait for resources. See scsi_probe(9F) for defined return values if no resources are available.
Wait indefinitely for resources.
