Availability groups (AG’s) is one of my favorite features of SQL Server, despite some DBA’s catalogue them as “too complex” to implement, configure, manage and maintain … I just love AG’s. There is no question that AG’s are a very powerful high availability (HA) and disaster recovery (DR) solution, but as any software product eventually will have some issues but nothing is impossible to solve with a little bit of research.
The error message 19405 is a very common “issue” when configuring AG’s for a Failover Cluster instance (FCI) .
I’m a Microsoft Data Platform MVP also a very experienced multi platform DBA (MySQL, Oracle, SQL Server, SQL Azure) with over 10 years of experience in the database field.
I work in database support as primary consultant and DBA manager for larger US based companies in the healthcare, insurance, retail, food and energy industries.
I have a few certifications under my belt MCSE, MCSA, MCP, MCTS, ITIL v3, Docker, Kubernetes and RedHat openshift.
