The Upgrade Advisor tool analyzes your current instance of SQL Server and provides important information you should know before upgrading. For more information about SQL Server 2008 R2 Upgrade Advisor, see the Upgrade Advisor section of this Feature Pack download page.

Failover Clustering Rolling Patch and Service Pack Process

This knowledge base (KB) article describes how to apply a Microsoft SQL Server 2008 R2 update to a failover cluster instance. Although the article says "SQL Server 2008", it also applies to Microsoft SQL Server 2008 R2 Enterprise and Microsoft SQL Server 2008 R2 Standard (see the "APPLIES TO" section at the bottom of the article for a full list).

Important

  • If you update a SQL Server failover cluster instance on an active node, SQL Server services will be stopped. This causes SQL Server downtime. To avoid downtime, install a rolling update on passive nodes as explained in this article.
  • To avoid a mixed version of possible owner nodes in the failover cluster instance, use the Cluster Administrator tool (Cluadmin.exe), to remove nodes from the possible owner nodes list in the failover cluster instance. You should avoid having a mixed version of possible owner nodes to prevent possible data corruption.
  • In SQL Server 2008 R2, the cluster service checks the SQL Network Name resource for a list of possible owners. The SQL Network Name resource is also checkpointed. This behavior differs from SQL Server 2005. In SQL Server 2005, the SQL Server resource itself is checkpointed.
