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

SYNOPSIS
     #include 



     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, con-
                  sisting 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)  struc-
     ture  may  be initialized during the HBA driver's attach(9E)
     to point to an HBA driver function to be called by the  sys-
     tem  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.
