HWNLM0716E There needs to be at least two common fabrics between host Host and storage subsystem Subsystem in order to use the redundant fabric option.
Explanation
In order to use the redundant fabric option, there needs to be at least two common fabrics between the host and storage subsystem. For virtual disks, an I/O group requires two nodes to be connected to at least two common fabrics. If only one node of the I/O group has a working connection to the fabric, then the I/O group cannot be used for path planning.
Action
Either clear the redundant fabric option or select a host and storage subsystem that have two fabrics common between them and try again. For virtual disks, check the status of the connectivity of the nodes of the I/O groups on the SVC. Ensure both nodes of each I/O group have a working connection to at least two common fabric(s) as the selected host(s) and then reprobe the SVC and the fabric(s). Once the probes complete, try again.
