Dear All,
We have installed Exchange 2010 DAG with the following architecture:
AD and Exchange 2010 in Site A 172.16.1.0/24
AD and Exchange 2010 in Site B 172.16.101.0/24
172.16.1.0/24 and 172.16.101.0/24 subnets are for MAPI
192.168.1.0/24 and 192.168.101.0/24 are for replication
NIC 1 is connected via sonic wall site to site vpn for MAPI
NIC 2 is connected using vyatta site to site vpn for replication
Everything was working well until the exchange 2010 in the main site auto reboot after an update. The issue we are having is that when we failed back to the
main site after the exchange 2010 in site A came back oniline it automatically switches back to Site B. User's outlook shows that it is connected to site B
exchange server.
We did a validation check and got the following errors and the other errors are from the Cluster event viewer.
Your help is highly appreciated.
Thank you in advance.
Validation errors
Validate Resource Status
Validate that cluster resources are online, and list the cluster resources that are running in separate resource monitors.
Validating cluster resource Name: DAG.
Validating cluster resource File Share Witness (\\Node2.abc.com\DAG.abc.com) (\\Node2.abc.com\DAG.abc.com).
Validating cluster resource IP Address: 172.16.101.12.
This resource does not have all the nodes of the cluster listed as 'Possible Owners'. The group that this resource is a member of will not be able to come
online on any node that is not listed as a 'Possible Owner'.
Validating cluster resource IP Address: 172.16.1.12.
This resource is marked with a state of 'Offline'. The functionality that this resource provides is not available while it is in the offline state. The
resource may be put in this state by an administrator or program. It may also be a newly created resource which has not been put in the online state or the
resource may be dependent on a resource that is not online. Resources can be brought online by choosing the 'Bring this resource online' action in Failover
Cluster Manager.
Validate Software Update Levels

The servers do not all have the same software updates.
Cluster Events errors
Cluster node 'Node1' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to
the node having lost communication with other active nodes in the failover cluster. Run the Validate a Configuration wizard to check your network
configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any
other network components to which the node is connected such as hubs, switches, or bridges.
