link between primary site and dr site disconnected

To delete replication objects using low level commands  "stop, disassociate, remove" is an alternative to delsec and delpri as delsec and delrpi will only work for clean states.

If replication is disconnected then this means there is a problem between replication IPs (or a problem on the node like replication service group is offline or problem with VVR daemons).  The cluster gets its information using the cluster IPs which should be different IPs to replication, so replication being disconnected should not effect communication between clusters.

I suspect you have incorrectly configured the network somewhere or your script to remove IPs on Application IP is breaking things, for example it may be messing up the routing table so that communication between replication IPs stops working.
