we like to have a PowerShell-Script (running on every node on the cluster) monitoring the CSV and stopping the group hosting the SQL resources if CSV failures happen

    Question

  • In WFC a shared disk device has a dependency on a cluster resource like SQL Server. With the introduction of CSV (Cluster Shared Volumes) this dependency isn't there any longer because we assume that a CSV is always there. That's right (sometimes), but if a SAN failure happens, the CSV or several volumes presenting the CSV will be gone and SQL Server will start again. Ths brings SQL Server in an unpredictable situation and happened.
