we were applying fix pack on hadr based databases. first we had to apply fix pack on the standby database(node) and make standby node as a primary node by issuing takeover command. then after that we applied fix pack on primary node which is now standby every thing went through and we were successful in installing fix pack on both the node.
but the problem was hadr was in disconnected peer state.
my question is how can we bring hadr to peer state from disconnected peer state?
what are the commands we have to issue
i also know we should check db2diag.log and find out the errors why hadr could not go in peer state.
the only I could recommend - stop hadr on bot nodes and start hard again /standby/primary
and takeover where needed..
