There are still some problems to retrieve the wwn(port-wwn,node-wwn) of device
in XXX_attch or XXX_info entry point by call ddi_prop_op
example as :
ddi_prop_op(DDI_DEV_T_ANY, dip, PROP_LEN_AND_VAL_ALLOC,
DDI_PROP_DONTPASS, "wwn", (caddr_t)&propval, &proplen)
,
ddi_prop_op(DDI_DEV_T_ANY, dip, PROP_LEN_AND_VAL_ALLOC,
DDI_PROP_DONTPASS, "port-wwn", (caddr_t)&propval, &proplen)
or
ddi_prop_op(DDI_DEV_T_ANY, dip, PROP_LEN_AND_VAL_ALLOC,
DDI_PROP_DONTPASS, "port-wwn", (caddr_t)&propval, &proplen)
my purpose which like vchi is to get physical path and replace by my own
logic path.
now ,i face the above problem to get the wwn(port or node wwn) of lun . How
vchi implement it .
I hope your help, thank you
