tran_tgt_free

tran_tgt_free(9E)						Driver Entry Points						 tran_tgt_free(9E)

NAME

       tran_tgt_free - request to free HBA resources allocated on behalf of a target

SYNOPSIS

       #include <sys/scsi/scsi.h>

       void prefixtran_tgt_free(dev_info_t *hba_dip, dev_info_t *tgt_dip, scsi_hba_tran_t *hba_tran, struct scsi_device *sd);

INTERFACE LEVEL

       Solaris architecture specific (Solaris DDI).

PARAMETERS

       hba_dip	       Pointer to a  dev_info_t structure, referring to the HBA device instance.

       tgt_dip	       Pointer to a  dev_info_t structure, referring to the target device instance.

       hba_tran        Pointer to a  scsi_hba_tran(9S) structure, consisting of the HBA's transport vectors.

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

DESCRIPTION

       The  tran_tgt_free()  vector  in  the  scsi_hba_tran(9S) structure may be initialized during the HBA driver's attach(9E) to point to an HBA
       driver function to be called by the system when an instance of a target device is being	detached.   The  tran_tgt_free()  vector,  if  not
       NULL,  is  called  after the target device instance has returned successfully from its detach(9E) entry point, but before the dev_info node
       structure is removed from the system. The HBA driver should release any resources allocated during its tran_tgt_init() or  tran_tgt_probe()
       initialization performed for this target device instance.
