OASyS 6.2 Hot and Standby Racing
SCADA OASyS 6.2, dual system. The two servers don't want to work as hot and standby.

I have an old SCADA OASyS 6.2 and I am facing a big issue. I have two servers (dual hot/standby system). When I start the first server and became hot & stable then I begin to start the second one which should be the standby one, it starts so normal and became standby but after a very short time it switch automatic to hot and first server which is hot turned to fail.

So they don't want to work with each other. Every one wants to be a solo hot one.

Any tips?
