DMX SRDF config

Dears,

sub : SRDF config on DMX3

I have added new devices to source and target .. and then I have created the pair with the command

symrdf createpair -f c:\rdfout.txt -type r1 -sid xxx -rdfg xxx -invalidate r2

and then added device to the existing group

symld -sid xxx -g AAA add dev XXX

symrdf -g dg_rdfg100 set mode acp_disk DEV70

and then I have change the mode to synchronous

symrdf -g XXX set mode sync

But, the newly created devices not getting synched and still in suspended mode

DEVxxx  03EF RW       0  1657260 NR 02C7 WD       0        0 C.D-  Suspended

DEVbbb  03F0 RW       0  1657260 NR 0195 WD       0        0 C.D-  Suspended

please kindly guide me to resolve this
