Exchange 2010 DAG errors

Just thought of listing out some recent DAG error I worked and resolved… Happy to help!!!

FSW or the File Share Witness will fail to come online on one node for Exchange 2010 Database Availability Group running Windows Server 2008 R2.

Events:

System Log – Event ID 1564 –

Indicates that the cluster cannot access the file share witness directory. 
File share witness resource ‘File Share Witness (\\EXCHCAS.domain.com\DAG1.domain.com)’ failed to arbitrate for the file share ”. Please ensure that file share ” exists and is accessible by the cluster.

Use PsExec v1.98 to ensure you can connect to the FSW: http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx

I suspected this was an issue with either network itself or Permissions on the FSW

Tried the following steps:

  1. Stopped the FSW share
  2. Renamed that folder
  3. Recreated it:
  4. Open EMC
  5. Go to the properties of the DAG under Organization Configuration- Mailbox
  6. Change the name of the witness directory, removed it and then click Apply
  7. Now a new directory and FSW created

Set-Databaseavailabilitygroup -Witnessdirectory “c:\FSWFolderName” -Witnessserver “FSWServerName” -ID “DAGName”

All set…

Resolution 
======================== 
We analyzed the Exchange Best Practice Analyzer, the Application and System Logs and the DAG Tasks. 
We saw that the first error is received at this point:

Resolution 
======== 
Set servers Exch1.domain.com and Exch2.domain.com the Registry Key "DisabledComponents" to 0xFFFFFFFF and we restarted the Servers. 
How to disable IP version 6 (IPv6) or its specific components in Windows 7, 
in Windows Vista, in Windows Server 2008 R2, and in Windows Server 2008: http://support.microsoft.com/kb/929852 
On the mailbox servers Exch1.domain.com and Exch2.domain.com disabled these 3 Features (TCP Chimney Offload, Receive Side Scaling, and Network Direct Memory Access): 
Disabled the Firewall and then tried to add the Server Exch2.domain.com to the DAG again. 

 

All set – Now enabled firewall once again.

    Nice article Ratish.

    If we just uncheck the IPv6 from network connection properties then it causes this issue and this should not be done. It is like roadies everything or nothing. So we should disabled IPv6 completely using ffffffff or keep it checked in network connection properties.

    I propose to keep the firewall off and firewall service running, unless we have configured the firewall to allow the required ports.

  2. xunyang Says:

    i think this is only a workaround. actually, disable IPV6 and firewall is not the root cause. espically, disable firewall is a bad idea.

  3. Bill Rowland Says:

    I have not tested, however disabling IPV6 has not been tested in best practices. Most recommend that you do not disable IPV6 as DAG services uses part of the stack to communicate. Have you been able to fully test this?

    In my case DHCP Client service was not started. Please make sure to start DHCP service and add again. Hope this will help.
