To create a consistent Snapshot copy of a LUN without disruptions, it is necessary to quiesce I/O to the LUN. This process involves pausing or temporarily stopping the input/output operations to ensure that the data is in a consistent state when the snapshot is taken. This method is crucial for maintaining data integrity and consistency in the snapshot.

When the number of paths exceeds the recommended configuration for SAN deployment, it can cause performance issues. To address this problem, you can:

Use Selective LUN Mapping (SLM): SLM allows you to control which LIFs (Logical Interfaces) are used to access specific LUNs, thus reducing the number of paths and potentially improving performance by aligning with best practice configurations.

Reconfigure the fabric switch zoning: Adjusting the zoning on the fabric switches can help manage and optimize the number of paths, ensuring that there are not too many paths that could lead to inefficient I/O operations and performance degradation.

The correct tool for designing an FC SAN solution consisting of a NetApp ONTAP system, Broadcom switches, and servers is the "NetApp Verified Architecture" (NVA). The NetApp Verified Architecture provides comprehensive blueprints and detailed implementation references. These blueprints are thoroughly tested, prescriptive in nature, and designed to minimize deployment risks and accelerate time to market. They are specifically designed to help ensure that the architecture meets the high standards required for enterprise environments.

NVA documents include design guides, best practices, and detailed configuration steps, making them invaluable for planning and deploying complex solutions like the one described.

For more information, you can refer to the official NetApp documentation on NetApp Verified Architectures:
