Replace director card on the DMX 3 950

Dear All,

I would like to know if there is any pre-checking before replacement director card.  I know that the bin file saved on the storage but how can I check the configuration can be used, in case of the two director card fault , and need to restore the bin configuration after replacement director card?  

May I know what is the command can check the all director card port  mapping which PWWN , then I can find pwwn to which server connection ?

I run symmaskdb -sid xxxx list database  but there is not clear picture the connection .  

Thank you 

Hong
