Installing SQL 2017 on a cluster

Remote onto node-1 with the SQL DVD inserted (or mounted), and Windows Failover Cluster already created with shared drives D, L, T, and S. (and ideally Z for backups, but not in this case).


  • Re-boot (if “access denied” end task “Service Host: DCOM Server Process Launcher (4)”)
  • From Failover Cluster Manager run “validate cluster” (expect warnings for software level and only one network)
  • Copy media to local drive (IE: SQL Server, CU, and maybe SSMS)
  • Ensure you have service accounts for Engine and Agent.
  • Take a screenshot of Windows uninstall screen – to aid possible uninstall
