My experience in SCOM 2012 installation.

Unlike SCOM 2007, you don’t have a step to have a prequisite checker, but if something is missing, it shows you error at the time of installation

 

Please check the supported configuration document for OM2012 before the deployment.

Prepare your environment for OM2012 here

  

I
will go ahead and check Management server and Management console

Take it to default location


 I
Get the failure. This feature needs to be installed to continue further


 I
installed report Viewer and go next. Specify MG name. Anything that you wish to. But unique.

 

Add the SQL server name. If it’s a default instance, then just a Server name will do

 

 

Next
is your DW database name. Applies same as of above step.

Next
all your accounts that you may have already defined. Refer to the TechNet
article for account access

Read
the warning and go ahead and select the option you would want to go ahead with

 

Review
your settings and go ahead with install


 

And it’s completed. It’s approximately 15-20 min for installation.
 

Next step happens to deploy the agents to the servers. Refer
to below quick start guide by Kevin Holman.
