Hello. I have an issue with network configuration for DAG. DAG consists of two servers: SR-EX07 (Mailbox server), SR-EX10 (CAS/HUB/Mailbox) Exchange Server 2010 SP2 RU2 instaled on both. Servers located in different datacenters connected via Cisco site-to-site VPN. Separate AD sites configured for both locations. There are two network interfaces configured on each server. One for MAPI and other for replication traffic. SR-EX07: NIC1(MAPI)-172.17.8.77, (network 172.17.8.0/24) NIC2(Replication)-10.101.2.2, (network 10.101.2.0/30) SR-EX10: NIC1(MAPI)-172.16.19.195, (network 172.16.19.192/27) NIC2(Replication)-10.101.1.2, (network 10.101.1.0/30) Configuration of DAG Networks: Name : MAPI network Subnets : {{172.16.19.192/27,Unknown}, {172.17.8.0/24,Up}} Interfaces : {{SR-EX07,Up,172.17.8.77}, {SR-EX10,Up,172.16.19.195}} MapiAccessEnabled : True ReplicationEnabled : False Name : Replication network Subnets : {{10.101.1.0/30,Up}, {10.101.2.0/30,Up}} Interfaces : {{SR-EX07,Up,10.101.2.2}, {SR-EX10,Up,10.101.1.2}} MapiAccessEnabled : False ReplicationEnabled : True and finally... DatabaseAvailabilityGroupIpv4Addresses : {172.16.19.210, 172.17.8.199} Replication works fine. Network 172.16.19.192/27 is in UNKNOWN state, and after I added second IP for DAG (172.16.19.210) it did not appear in a cluster resources. Cluster configuration: EXDAG1 Name : Address Value : 172.17.8.199 Name : SubnetMask Value : 255.255.255.0 Cluster networks: Name : SR-EX07 - NIC1(MAPI) Node : SR-EX07 Network : Cluster Network 1 State : Up Name : SR-EX10 - NIC1(MAPI) Node : SR-EX10 Network : Cluster Network 1 State : Up [both MAPI interfaces in one cluster network, but in different subnets, why?] Name : SR-EX10 - NIC2(Replication) Node : SR-EX10 Network : Cluster Network 2 State : Up Name : SR-EX07 - NIC2(Replication) Node : SR-EX07 Network : Cluster Network 4 State : Up I ran cluster verification - without errors, tried to remove SR-EX10 from DAG and join it again - no result. In this situation, when server SR-EX07 fails, MAPI connections are fails too. Help me! :)
