Yeah suspend only affects the link and would leave device states as is.
Hi Folks,  we are performing a DR excersise and  there are thousads of devices in a device group and we have to suspend it.   Would the "symrdf -g dggroup suspend" suspends only the link? Will it leave the R1's in RW(present state) state and R2 in WD(presnet state).  Essentially what I am looking is  to halt the traffic between R1 and R2 and leave the device states as is. Would the above command serve the purpose?  Thanks in Advance.
