Exchange tree Node Cluster Ressources are unexpectedly unavailable
Posted on 2006-11-27
We have an three Node Exchange 2003 Cluster.
Once a week one of the ressources are not available, the users are communicating that Outlook will not connecting the Exchange Server.
Showing the Cluster Administrator, all of the ressources are all up and running.
First I had the look on the storage box, controlled all versions to be at recommended versions supported by the manufacturer. I have found some signs that the transactions logs could not be written. Now we are shure that the versions of the storage related software and drivers are correct.
I'm now occupied to merge all the concerning events into one overview.
I'm not very familiar with a Clustered Exchange environment. Can anyone please help me to analyse and resolve that problem. Is there a way to log what's going wrong and find some hints?
Some details about the environment:
Windows Server 2003 SP1
Exchange Server 2003 SP2
2 Virtual Servers Active/Active
This is an environment with approximate 100 Exchange Servers in as much routing groups
Please excuse my bad english.
Thanks in advance for your help
