CreateCluster failed with 0×5 adding members to DAG in Exchange 2013

Last weekend I was building a Exchange 2013 cluster. Since everything so far was working as expected, I proceeded with creation of DAG. From EAC, creating DAG itself worked with no issues. I then went ahead and added first mailbox server to DAG. this step, however, refused to complete with error:

A server-side database availability group administrative operation failed. Error The operation failed. CreateCluster errors may result from incorrectly configured static addresses. Error: An error occurred while attempting a cluster operation. Error: Cluster API ‘”CreateCluster() failed with 0×5. Error: Access is denied”‘ failed.. [Server: ward-02.wardvissers.local]

Assigning “Full Control” to Exchange Trusted Subsystem on , I assumed should fix the issue, however, it actually produced a completely different error when I tried to add the mailbox server to DAG again:

An Active Manager operation failed with a transient error. Please retry the operation. Error: The fully qualified domain name for node ‘DAG01′ could not be found.

Solution:

Pre-stage the CNO (CLUSTER NAME OBJECT)

  1. Open Active Directory Users and Computers.
  2. Expand the forest node.
  3. Right-click the organizational unit (OU) in which you want to create the new account, select New, and then select Computer.
  4. In New Object – Computer, type the computer account name for the CNO in the Computer name box. This is the name that you’ll use for the DAG. Click OK to create the account.
  5. Right-click the new computer account, and then click Disable Account. Click Yes to confirm the disable action, and then click OK.

Assign permissions to the CNO (CLUSTER NAME OBJECT)

  1. Open Active Directory Users and Computers.
  2. If Advanced Features aren’t enabled, turn them on by clicking View, and then clicking Advanced Features.
  3. Right-click the new computer account, and then click Properties.
  4. In <Computer Name> Properties, on the Security tab, click Add to add either the computer account for the first node to be added to the DAG or to add the Exchange Trusted Subsystem USG:
    • To add the Exchange Trusted Subsystem, type Exchange Trusted Subsystem in the Enter the object names to select field. Click OK to add the USG. Select the Exchange Trusted Subsystem USG and in the Permissions for Exchange Trusted Subsystem field, select Full Control in the Allow column. Click OK to save the permission settings.
    • To add the computer account for the first node to be added to the DAG, click Object Types. In the Object Types dialog box, clear the Built-in security principals, Groups, and Users check boxes. Select the Computers check box and click OK. In the Enter the object names to select field, type the name of the first Mailbox server to be added to the DAG, and then click OK. Select the first node’s computer

Exchange 2013 Cumulative Update 1

Today the long-awaited Cumulative Update 1 for Exchange Server 2013 was released by the Exchange Team (KB2816900). This update raises Exchange 2013 version number to 15.0.620.29.

This is the Exchange 2013 product level required for co-existence with previous versions of Exchange, being Exchange Server 2010 SP3 or Exchange Server 2007 SP3 Rollup 10.

The Exchange Team provided a description of the major changes in CU1. You will find the announcement here; Here are some of the major changes in CU1:

  • Includes Address Book Policy Routing Agent (info);
  • Allows group memberships to be managed by groups (again, as it was possible in Exchange 2007 but not in Exchange 2010);
  • Access to Public Folders you have added as favorites via your favorites menu either in Outlook or Outlook Web App (still no regular Public Folder tree access though);
  • EAC has been enhanced and now includes Unified Messaging management and migration options;
  • Many probes, monitors, and responders have been updated and improved over the RTM release;
  • Get-HealthReport cmdlet has been streamlined and its performance has been optimized;
  • Supports the Exchange Server 2013 Management Pack for SCOM 2007 R2 and SCOM 2012 (due at a later date);
  • High Availability changes

Note that CU1 includes a schema change. Like Service Packs for earlier versions of Exchange, the Cumulative Update is indeed cumulative (hence the size of 1.3 GB) and you can install it directly, i.e. no need to install RTM first. Also, once installed you can’t uninstall CU1 or any of the installed roles. The order of upgrading servers doesn’t matter, unlike with earlier Exchange versions.
