We use SCCM 2012 in our environment for patching windows servers.
We found that a security patch called ‘KB2977320’ (security update for SQL 2008 R2) was installed on our SQL Disaster recovery servers. But same patch not installed on our production SQL cluster nodes. Is there any reason why SCCM chose to selectively install a patch on set of servers but not others? We want to avoid this in future patching. Kindly advice.
