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)  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.
