During a maintenance window, we needed to swap out our main network LAN switch at our DR site.  In the process of trying to get the old switch out of the rack, we accidentally unplugged our CS0 device.  We did not notice it off at first.  Once we did we pligged it back in.   I thought I managed to get that as the primary again, but I may have done something wrong.  And now, when i checked my replication pairs, they are saying they last updated May 10, the same night the CS0 went offline...

So, how do I make sure my CS0 is set to primary?

Why do these CS seem to be very sensitive when one fails?  Or do I just not understand how this works... (which could very well be the case)

Now that replication is in some "paused" state, how do I get it going again?  Will it just work once the CS0 and CS1 are straightened out?
