Change IP Address of CCR Cluster nodes RRS feed

  • Question

  • We are changing our network subnet because of some network additions. We have an Exchange 2007 CCR Cluster.

    I am thinking of the following procedure to change the CCR nodes IP Addresses.

    1. Add an additional IP Address to CCR Nodes.

    2. Change the default gateway to new netwrok gateway.

    3. Change the IP ADdress of the cluster using cluster administrator.

    4. Change IP Address of the Exchange CCR using cluster administrator.

     

    Is this a workable solution? Is there any challenges we will face in this procedure?

     

    Thanks,

  • Remember that you have not only the Windows cluster IP addresses, but the clustered mailbox server IP address.  I think that's what you mean by step 4, but want to be sure because you didn't say "CMS address".  Also, if you are using continuous replication hostnames to facilitate replication over the heartbeat network, then you may or may not have additional addresses to change.

    I would suspend storage group replication on all storage groups before making the change, and resume it afterward.  I'd also make sure I had a good backup.

  • Let me add that you should stop the clustered mailbox server beforehand too.

  • Hi Ed,

    As per your suggestion, stop the clustered mailbox, does that means there will be outage to the Mailbox server service ?

    My understanding is that when we fail over to DR node, then the current passive node IP address can be changed safely without impacting the mail flow.

    is that possible or still I have to take down email service entirely ?

  • Ed,


    I wonder if I can just change one of the passive node IP address and then followed by the failover to the other node and change it again ? in that way there will be no downtime.

    would that be possible after turning off all of the Exchange Server service

    I will be changing the following IP address in the production node:

    NIC 1 public IP
    NIC 1 CMS Virtual IP
    NIC 1 MSCS virtual IP

    Nic 2 Cluster Private network IP 1 (which receive the mailbox replication data from DR mailbox node)
    Nic 2 Cluster Private network IP 2 (which send the mailbox replication data to DR mailbox node)
