Re-installing the Cluster nodes in an Exchange 2007 CCR-based Mailbox Server Setup (Part 2)

If you missed the first part in this article series please read Re-installing the Cluster nodes in an Exchange 2007 CCR-based Mailbox Server Setup (Part 1).




In the previous article, we uninstalled the passive clustered mailbox role from the first CCR node, evicted the node from the Windows cluster and then re-added the node to the Windows cluster after the operating system had been re-installed and configured accordingly.


In this part two of this articles series, we can move on where we left off in part one by installing the passive mailbox role. To do so, launch Exchange 2007 Setup.exe, and then click Install Microsoft Exchange Server 2007 SP1 (Figure 2.1).


The clustered mailbox server in the lab I’m using for the purpose of this article is running Exchange 2007 SP1, which is why I use the Exchange Server 2007 SP1 binaries to re-install the passive Mailbox role. If you’re CMS haven’t yet been upgraded to Exchange 2007 SP1, it’s important you use the Exchange 2007 RTM binaries to re-install the passive Mailbox role.

On Introduction page, click Next > accept the License Agreement and click Next. Decide whether or not you want to enable error reporting, and then click Next once again.


On the Exchange 2007 Setup Installation Type page, select Custom Exchange Server Installation and click Next (Figure 2.2).

Now tick Passive Clustered Mailbox Role. If you installed the Exchange 2007 binaries at another location than the default, this is also the page on which you change the installation path (Figure 2.3). Click Next.

The readiness checks will now be performed. This will normally complete without any issues or errors, but if you like me forgot to remove the database and log files from the Database or Log file LUNs, you’ll receive an error similar to the one shown in Figure 2.4.

When removed, you should see a Readiness Checks page like the one in Figure x (of course without the 32-bit version warning). Click Install.

The installation process will now begin and after a few minutes you should get a completion page as shown below (Figure 2.6).

Now that the Exchange 2007 SP1 binaries have been installed, we must reboot the node before continuing with the next steps.


Next step is to reseed the storage group copies, so that the CCR node gets up to date replicas of each the active databases. This can be done using the Exchange Management Shell and when speaking Exchange 2007 SP1 the Exchange Management Console (EMC) UI. In this article, we’ll use the EMC UI, so launch the EMC. In the EMC, select the clustered mailbox server under the Server Configuration work center. As we can see in Figure 2.7 below, the copy status is currently in a failed mode, which is expected.

If we open the Property page for one of the storage groups and click on the Cluster Continuous Replication tab, we can also see that no logs have been copied to the newly installed CCR node.

To seed the passive node, select a storage group and click Update Storage Group Copy in the Action pane (Figure 2.9).

On the Update Storage Group Copy Introduction page, click Next (Figure 2.10).

On the Summary page, click Update (Figure 2.11).

If you receive the warning shown in Figure 2.12, click Yes.

After a while (depending on the size of the databases) you’ll be taken to the Completion page (Figure 2.13), where you simply click Finish.

The storage group will now be in a healthy state (Figure 2.14) and any log files will have been copied to the passive node (Figure 2.15).

You must run the Update Storage Group Copy wizard for any existing storage groups.


Re-installing the Second CCR Node


Time has come to re-install the second CCR node. Since the steps are identical to the ones we went through in order to re-install the first CCR node, I won’t repeat them. Just go back to part one of this articles series and follow each step until you end up here again.




As you have seen throughout this article, although CCR-based clustered Mailbox server scenarios can be complex, it is a straightforward task to re-install the nodes in such as scenario. But with that said, if you do not follow the right steps in the right order, your day (or perhaps week!) can quickly be ruined. This article helps you through the process without any downtime to your end users at all.
