September 16, 2015September 16, 2015 Mustafa EL-Masry Errors

Cannot add new node in SQL Server 2014

Problem

Hi my followers today i have task to build two new SQL Server Clusters when i am working i go to for adding new Node at this time i revived very new issue for me Rule “SQL Server Database Services feature state” failed

—————————
Rule Check Result
—————————
Rule “SQL Server Database Services feature state” failed. The SQL Server Database Services feature failed when it was initially installed. The feature must be removed before the current scenario can proceed.
—————————
OK
—————————

This error meaning When you are adding the first node the cluster installed with some issues and this relay what is happened with me when i installed the First node i faced some issues so based on that adding second node is blocked

How i can fix this issue :

To fix this issue at the first you should check the Cluster error log in the first node and try to do prepare for this node

If this step not success with you to fix this issue you can try the second solution :

Go for the Run
Write Regedit
Go for this path (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQLServer\MSSQL12.MSSQLSERVER2014\ConfigurationState )
Check all the value for all the Component if you found the value is 2 this meaning you have failures in this Component change it to 1

Component name :

MPT_AGENT_CORE_CNI, SQL_Engine_Core_Inst, SQL_FullText_Adv, SQL_Replication_Core_Inst

Note : to find the correct place in the registry you after this path (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQLServer\) we have to know Our SQL Server Version and SQL Server instance name
