Verifying that the configuration is capable of nondisruptive operations

You can verify that the Hyper-V or SQL Server over SMB configuration is healthy and able to perform operations nondisruptively by displaying health monitor information, verifying that the SMB shares are shared persistently, and by verifying the status of the LIF configuration.

  • How to use health monitoring to determine whether nondisruptive operation status is healthy
    Health monitoring provides information about system health status across the cluster. The health monitor monitors Hyper-V and SQL Server over SMB configurations to ensure nondisruptive operations (NDOs) for the application servers. If the status is degraded, you can view details about the problem, including the probable cause and recommended recovery actions.
  • Displaying nondisruptive operation status by using system health monitoring
    You can use the system health commands to display information about the overall system health of the cluster and the health of the CIFS-NDO subsystem, to respond to alerts, to configure future alerts, and to display information about how health monitoring is configured.
  • Verifying the continuously available SMB share configuration
    To support nondisruptive operations, Hyper-V and SQL Server SMB shares must be configured as continuously available shares. Additionally, there are certain other share settings that you must check. You should verify that the shares are properly configured to provide seamless nondisruptive operations for the application servers if there are planned or unplanned disruptive events.
  • Verifying LIF status
    Even if you configure storage virtual machines (SVMs) with Hyper-V and SQL Server over SMB configurations to have LIFs on each node in a cluster, during day-to-day operations, some LIFs might move to ports on another node. You must verify LIF status and take any necessary corrective actions.
  • Determining whether SMB sessions are continuously available
    You can display information about SMB sessions and SMB open files to determine whether they are continuously available.
