Multi-admin approval (MAA), also known as multi-admin verification, is a security feature in ONTAP designed to prevent a single administrator from performing critical destructive operations, such as deleting a volume. Once this feature is enabled on a cluster, it cannot be disabled by a cluster administrator through either the command-line interface (CLI) or ONTAP System Manager. The only sanctioned method to disable this security control is to contact NetApp Support, who will guide you through a verified process. This restriction ensures the integrity of the dual-control security principle that MAA enforces.

A. Multi-admin approval can be disabled, but it requires intervention from NetApp Support; it is not a permanently enabled feature.

C. The -force parameter in the volume delete command is used to bypass operational warnings (e.g., deleting a volume that is online), not security workflows like multi-admin approval.

D. A simple toggle in System Manager would defeat the purpose of a multi-person security control, as a single administrator could easily bypass it. Therefore, this option is not available.

1. NetApp ONTAP Documentation, "ONTAP concepts > Security and data encryption > Multi-admin verification": This document states, "When multi-admin verification is enabled, you cannot disable it. You must contact NetApp Support to disable it." This directly confirms that a support case is the required procedure.

2. NetApp ONTAP 9 Commands, security multi-admin-verify Manual Page: Examination of the command set for managing MAA (security multi-admin-verify) shows commands to create, approve, reject, and veto requests, but there is no disable or modify command available to the administrator to turn the feature off once enabled. This reinforces that the control is outside the administrator's direct management.
