Hi I recently inherited an Exchange 2010 and am trying to come up to speed in a hurry with it but am having a hard time sorting something out in my mind.
This is the RTM version. We are installing SP2 and virtualizing the Exchange servers in 3 weeks.
I have a two node DAG group that has been working but now we are having some replay log issues. The question I have specifically is in the Failover Cluster Manager. If I look under the Cluster Core Resources It shows:
Name: Dag1 Online
IP Address: x.x.x.x Online (This is our internal trusted network)
IP Address: Add on Cluster Network 3 Offline
IP Address: x.x.x.x Online (This is an IP that is in the subnet of the ISCSI connection)
IP Address: Address on Cluster Network 4 Offline
File Share Witness Online
Could this be right for a functioning DAG group that 2 IP Addresses are offline? Since I never went into the Failover manager before I am not sure what the normal operation is.
Any help is greatly appreciated.

Am not sure why your ISCSI connection is listed on the failover Cluster manager
But DAG part -
if - DAG and FSW is online.
DAG part will work fine.

Thanks for the response, when you say if if - DAG and FSW is online do you mean the
Name: DAG1 Online
that part as well as the Witness server being online means DAG will work?

Thursday, August 02, 2012 7:18 PMIt can be normal for the different IP Address to be offline. It depends on which subnet the cluster resource is currently being hosted on. If your Dag members are on different subnets, there should be one IP Address resource per subnet. That way, should that Dag member needs to become the Primary Active Manager, the cluster group resources can be hosted on that node. The cluster group will turn the different IP Address resources on and off depending on if it's even possible to host that IP Address on the subnet that the current hosting node is in.

Thanks for the additional responses. Everything is okay now.
The DAG is online and after I reseed the databases everything is in sync again.
