we had a fas-2040 named "naana006" and a fas-2040 named "naana030" at first , then we combined "naana006" and "naana030" to a new naana030 , the old naana006 became "naatest01" , at that time, the hostname "naana006" is no longer in use.
later we bought a new fas-2554 and we apply the "naana006" to it.
now when i add the ip of the fas-2554 to DFM, it turns out "naana006,fas-2040"
when i add the hostname "naana006",it turns out"naana006,fas-2040" too , not the fas-2554
in a word , it looks like that naana006 is still mapped to the old fas-2040 even if i use "dfm host delete" or "dfm controller delete" to delete the host.
