System Center 2012 R2 Configuration Manager prerequisite overview on Windows Server 2012 R2

Before you can start installing System Center 2012 R2 Configuration Manager in your environment you have to install the servers with an OS and configure its roles and features. While the Site System Installation Wizard now provides the option to configure some of the roles and features when not installed, I prefer to setup my environment upfront so that the Prerequisite Checker doesn’t give any Errors or Warnings to start with. My ex-collegue Tom Klaver already documenten the settings once for installing ConfigMgr 2012 RTM on Windows Server 2008 R2 – but since some things changed in the meantime i decided to update the spreadsheat to reflect installing System Center 2012 R2 Configuration manager on top of Windows Server 2012 R2. This information is coming from the following documentation on TechNet – Supported Configurations for Configuration Manager via: http://technet.microsoft.com/en-us/library/gg682077.aspx#BKMK_Win2k12SiteSystemPrereqsRead More

Some things to consider before installing the ConfigMgr database on a SQL cluster

Note: I’ve already posted this article a while ago, but since my ex-employer decided to whipe the whole website without asking me if I would like a backup it got lost. Therefore i decided to place it here again. Note that this is still valid for ConfigMgr 2012 installations, i’ve modified the article to reflect that.

The System Center Configuration Manager (ConfigMgr) database can be installed on a clustered SQL Server, some things work different though compared to installing ConfigMgr on a normal SQL server installation, and you should be aware of them before starting your installation.

To summarize in front, what you should take into account before starting your installation:

  1. Make sure that the SQL administrators are aware that during installation extra righs are needed and that after installation the Site server must stay local administrator on the cluster nodes
  2. Make sure that the SQL administrators are aware of the fact that ConfigMgr will install a service on the Cluster Nodes, which is used for creating the backup using VSS
  3. Make sure that each shared cluster disk contains a no_sms_on_drive.sms file on the disk
  4. Configure the Site Backup tasks, so that it is either configured to backup to an UNC path or a drive which is suitable for storing the backup files on both the site server and the cluster nodes using the “Different Paths for the Site Backup and Database backup” option

The self signed certificate could not be created successfully error in the Create Site System Server Wizard

Today, a customer contacted me with a very strange issue while installing a new Site System Server in his System Center 2012 R2 Configuration Manager environment.
