Reconfigure the FC switch layout for ONTAP 9.1 or later
If your existing FC switch layout was configured prior to ONTAP 9.1, you must reconfigure the port layout and apply the latest Reference Configuration Files (RCFs). This procedure applies only to MetroCluster FC configurations.
You must identify the FC switches present in the fabric domain.
You need the admin password and access to an FTP or SCP server.
You must perform this task if your existing FC switch layout was configured prior to ONTAP 9.1 and you are upgrading to a platform model supported in ONTAP 9.1 or later. It is not required if you are upgrading from an existing switch layout that was configured for ONTAP 9.1 or later.
This procedure is nondisruptive and takes approximately four hours to complete (excluding rack and stack) when disks are zeroed.
