This is the document I would refer to:
http://techsupport.services.ibm.com/server/aix.techTips?refNo=90605212214784
You should separate cdump and cdumpfs onto different disks.
There's no point in mirroring the dump LV, as the document explains. It
might be worth having two dump LVs, though.
I don't think that the LV type matters. I normally set it to "dump", but
there are very few commands which actually pay any attention to this
parameter. (I think just the paging space commands.)
