The fcadmin config command...

The clustershell is the standard ONTAP CLI for cluster-wide administration and does not include node-level hardware commands like `fcadmin config`.

The `fcadmin config` command resides in the nodeshell because FC adapter configuration is a node-level hardware operation. The nodeshell provides access to per-node administrative functions - such as setting an HBA port to target or initiator mode - that are not exposed in the cluster-wide ONTAP CLI (clustershell).

The systemshell is a low-level diagnostic shell used for advanced troubleshooting, not for routine FC adapter configuration tasks.

While many commands require advanced privilege mode within the clustershell, `fcadmin config` is specifically a nodeshell command and is not accessible from the clustershell at any privilege level.
