I have a dag with two subnets 10.66.0.0/16, 10.68.0.0/24. One of the subnets changed when a remote office ip subnet mask changed from class c to class b 10.68.0.0/16. I changed the ip of the remote
DAG member server to match the new class b mask i.e. 255.255.0.0 in its network configuration. After that the databases failed on the remote subnet member server. I changed it back (as the class was the first in the class b) and the failed
databases came back to healthy.
I tried to correctly set the subnet mask on the dag network in either EMC or EMS but I get the message:
Subnet '10.68.0.0/16' can't be set because it conflicts with existing subnet '10.68.0.0/24'
What are the correct steps to change the mask of an ip address for a DAG member server?
