In which shell can administrators natively run Data ONTAP 7-mode commands?

The node shell, accessed via the 'system node run' command from the cluster shell, natively executes Data ONTAP 7-mode style commands directly on an individual node. This shell exposes the underlying per-node ONTAP environment where 7-mode commands run as they would in a standalone system. It is primarily used for advanced troubleshooting and low-level configuration tasks not yet surfaced in the clustershell CLI.

The system shell provides low-level UNIX-like diagnostic access to the node OS but does not natively execute Data ONTAP 7-mode commands.

The cluster shell (clustershell) is the primary clustered ONTAP management interface and uses its own modern CLI command set, not 7-mode commands.

There is no distinct 'admin shell' context in Data ONTAP; this is not a valid shell type in the ONTAP architecture.

The diag shell is used for low-level diagnostic operations and does not natively run Data ONTAP 7-mode commands.
