Question

I am configuring WSFC and while doing it, I gave cluster name with more than 15 letters. As per below links only 15 letters cab be given to computer/host name.

http://superuser.com/questions/120751/how-long-can-a-windows-computer-name-be

Below image shows the screen where I am entering the cluster name with more than 15 characters.

After configuration, I can see the cluster created with name as shown below. It has 16 letters.

Looks good, but if I see the LOG file, I see CN name is truncated to 15 characters!!! as shown below

CN = MSFSQLDEVCLUSTE;

So my question is, can I ignore this ? will it affect me in future? If yes, how can I edit the cluster name? Do I have to delete and recreate with new name?

Found a link for recommended way. https://blogs.technet.microsoft.com/askcore/2010/01/11/deleting-a-cluster-resource-do-it-the-supported-way/ It suggest to use the command as shown below

CLUSTER.EXE Cluster res “MSFSQLDEVCLUSTE” /delete

OR

Powershell Remove-ClusterResource “MSFSQLDEVCLUSTE”

Is I am going in right direction?


Many Thanks Deepak

Hi Deepak,

The length of Windows Cluster name should be no more than 15.

You can change the cluster name by performing the following steps.
1. Open Failover Cluster Management MMC, right on the cluster name and select properties.
2. In General tab, change the existing cluster name to your desired name; click on Apply and then OK to complete the Task.

In addition, regarding to Windows cluster issues, I would recommend you post the question in the Windows Server High Availability (Clustering)  forum. It is appropriate and more experts will assist you.

There are similar threads for your reference.
