scsi_free(D3X)scsi_free(D3X)NAMEscsi_free - release communication channel to host adapter driver
SYNOPSIS
#include <sys/types.h>
#include <sys/scsi.h>
void
(*scsi_free)( vertex_hdl_t lun_vhdl,
void (*callback_function)(vertex_hdl_t, char *));
DESCRIPTION
The host adapter scsi_free function is used to terminate a connection
between a SCSI device driver and the host adapter driver.
There is no kernel object called scsi_free; rather, there is a pointer to
each host adapter's scsi_free function in the sci_free field of the
scsi_ctlr_info structure, which is attached to the vertex corresponding
to the host adapter.
lun_vhdl is the device vertex, as given to scsi_alloc to open the
channel. The callback_function argument must be the same as that given
to scsi_alloc.
NOTES
scsi_alloc is stored as a function pointer in the scsi_ctlr_info_t
structure, which is associated with the scsi host adapter vertex in the
hwgraph. The information structure in the scsi target vertex also has a
pointer to the scsi_ctlr_info_t of the host adapter that the target is
connected to. Given a lun_vhdl (vertex handle of the device) the
scsi_free function can be called as follows:
scsi_lun_info_t *scsi_lun_info;
...
scsi_lun_info = scsi_lun_info_get(lun_vhdl);
SLI_FREE(scsi_lun_info)(lun_vhdl,callback_function);
