Rebuilding CCR cluster mailbox Server 2007 after Ip address cahnges ?

Hi Folks,

Can you please assist me with the steps or way to correctly configure the CCR Cluster mailbox server (Exchange Server 2007 SP3) on my Windows Server 2008 ?

Because at the moment I'm planning to move only one of the Mailbox Server cluster CCR from one VLAN to another one keeping the same DNS name (different Data Center). The DR site is using the same IP address.

Can I just replace the old IP address of the following:

Windows Server IP address from the Network Adapter Properties
Cluster Mailbox Server IP address from the Exchange Management Shell
CCR replication link, From Prod - DR and DR to Production from the Failover Cluster Admin console

what else do I missed here ?

Any kind of help and assistance, would be greatly appreciated.

thanks.

Hi Suriya,

in the Steps described there:


Make sure that all resources are on ServerB (it doesn’t matter which server just make sure that all of them are on the same)
Stop cluster services on ServerA and change the service to Manual mode (using services.msc)
Logged on ServerB, dismount all databases using Exchange Management Console
Logged on ServerB, dismount all Cluster resources using Cluster Administrator (cluadmin)


Note: If you are using a MNS Quorum you wouldn’t be able to bring it down. Not a problem, keep reading..
Double click on IP Resource for the Cluster and change to the new Address
Double click on IP REsource for the CMS (Exchange Resource Group) and change to the new address
Close Cluster Administrator
Modify the Cluster Service to Manual (using services.msc)
Change the LAN Adatper to the new IP Address
Restart the machine
Test the Active Directory site information (nltest dsgetsite, nslookup, file:///C|/%3CDC-Name, \\<domain-FQDN>)
Test the network access in general
If it’s all good, Start the cluster service and change the service to Automatic
Open Cluster Administrator and bring up just the Cluster Resource Group and check from your workstation if you can ping the name of tha resource (here in our example is tocluster and its new IP address)
Awesome! At this point you have one node (ServerB) using the new IP address information and at least one resource
Logged on ServerA, change the LAN adapter to the new IP Address and restart that server
Logged on ServerA, test AD, network access like we did on steps 12 and 13
Start the cluster service and configure it back to Automatic (using services.msc)
Move the Cluster Resource Group between nodes, is it all good? CAn you access all services in both nodes?
Great we have new IP address on all nodes, at least one resource is working properly
Now, it’s time to bring it up Exchange Clustered Mailbox Server on ServerB

Does that means there will be an outage ?

taking down the Cluster Exchange Resource ?

I'm bit confused on the steps, since my understanding is that Server A will be changing its IP address, while Server B remains the same.

Thanks, does that needs an outage ?
