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

Solaris architecture specific (Solaris DDI).

Arguments

sd
Pointer to a scsi_device(9S) structure.
waitfunc
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:

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.
SLEEP_FUNC
Wait indefinitely for resources.
