No .. don't do that ... I would suggest bouncing the SECONDARY and seeing
if both servers sync up or not ... otherwise you'll have to do the physical
restore to re-establish HDR again from scratch ...

Rajib,
I have the same problem when I restored my latest backup to the Primary.
Can I just kill this user session that has the flag -X?
Thanks fo your help.
P.S. I can ping my secondary so my network connection seems to be good.

Rajib,
How do you bounce the Secondary?
Whenever I do the restore (i.e. using the same backup), I get the
same problem.
Pls advise.
Thanks.
