ADRDSSU and compatible Native Flash question

Hi,

I’m testing Compatible Native Flash on DMX-3 in mainframe environment. IBM Flash Copy commands works OK on volume level (I tested TSO FCESTABL with several options). But when I try to use FlashCopy in ADRDSSU, I receive message:

FAST REPLICATION COULD NOT BE USED FOR DATA SET AAA.BBB.CCC BECAUSE THE SOURCE DEVICES DO NOTPROVIDE COMPATIBLE DATA SET FAST REPLICATION FUNCTIONS  

Is it only one proper way to use fast replication in ADRDSSU on EMC boxes to rename EMCDSSU to ADRDSSU ?
