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)
- Open Active Directory Users and Computers.
- Expand the forest node.
- Right-click the organizational unit (OU) in which you want to create the new account, select New, and then select Computer.
- 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.
- 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)
- Open Active Directory Users and Computers.
- If Advanced Features aren’t enabled, turn them on by clicking View, and then clicking Advanced Features.
- Right-click the new computer account, and then click Properties.
- 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
