Virtual Port Mode with Single-Fabric Fibre Channel
Connect virtual port mode Fibre Channel to a single fabric if only one FC is available and
you want to protect against port or controller failure.
In this configuration, there is one fault domain because there is a single FC fabric. Each
controller is connected to the fabric by at least two FC connections to provide port
redundancy. If a single port fails, its virtual port fails over to another port. If a controller
fails, the virtual ports on the failed controller move to ports on the other controller. This
configuration is vulnerable to switch failure.
Prerequisites
Each controller must have two available FC front‐end ports.

The requirements for virtual port mode must be met.

Steps
1 Connect each server to the FC fabric.
2 Connect fault domain 1 (shown in orange) to fabric 1.
Controller A, slot 1, port 1 → Fabric 1
