I did this:
if (xpt_create_path(&tmppath, NULL, cam_sim_path(isp->isp_sim),
(target_id_t)tgt, CAM_LUN_WILDCARD) != CAM_REQ_CMP) {
break;
}
if (lp->valid && (lp->roles &
(SVC3_INI_ROLE >> SVC3_ROLE_SHIFT))) {
ISPLOCK_2_CAMLOCK(isp);
xpt_async(AC_FOUND_DEVICE, tmppath, NULL);
} else {
ISPLOCK_2_CAMLOCK(isp);
xpt_async(AC_LOST_DEVICE, tmppath, NULL);
}
CAMLOCK_2_ISPLOCK(isp);
xpt_free_path(tmppath);
This does a LOST or FOUND device async for that PATH (bus), that Target, and
all LUNS.
Note that xpt_bus_deregister has:
status = xpt_compile_path(&bus_path, NULL, pathid,
CAM_TARGET_WILDCARD, CAM_LUN_WILDCARD);
...
xpt_async(AC_LOST_DEVICE, &bus_path, NULL);
which then does lost devices on all targets and luns on that bus.
