Virtualization, Cloud, Infrastructure and all that stuff in-between

My ramblings on the stuff that holds it all together

Exchange 2007 SP1 Upgrade Process on a CCR cluster


I used this process to carry this out – worth bearing in mind that you do need some downtime to the clustered mailbox instance to carry this out – it took about 60 seconds to do that and installing the SP1 code on each passive node took approx 5 mins each + a reboot


Exchange 2007 CCR Configuration Notes


Once you’ve followed the installation process and have your active and passive nodes setup you may not actually be able to failover and mount the stores – it fails and logs an event 9317 from MSExchangeSA as below;


The fix is to register an SPN for each cluster node as per this KB article – why setup doesn’t do this for you I don’t know?

add-ADPermission -Identity “cn=exchange-cms,cn=computers,dc=mydomain,dc=com” -User “node-cl1$” -AccessRights WriteProperty -Properties “Validated-SPN”

You do this using the Exchange Management {Power}Shell Applet using the following command.

One thing to bear in mind – particularly if you are implementing a CCR cluster across mode than one physical site (single subnet required) you’ll need to wait for each node’s respective AD Domain Controller to replicate the changes.

Once that was completed I could fail over the cluster nodes perfectly.
