will a suspend/resume I/O from CVA cause data to be deleted or wiped out from DR groups, after the ISL was down and brought up.

It shouldn't.
It should kick the log into play and data will be logged until resumed, at which point a merge will happen (log --> destination).
even if you did not suspend, loss of the connection effective forces the source to start logging. (usually)

Re: EVA 5000 / CA
Hi Steven,
can we tell from the controller event log that the suspend/resume I/O did not cause data loss.
another question please, what if the ISL failure caused a split between both EVA's due to a new edge on the ISL with default setting in regards to CA (IOD, DLS,APTPOLICY).the new edge was removed and after that the suspend/resume was used.
