The procedure outlined in the question correctly identifies the essential software and hardware steps required to dissolve a Data ONTAP 7-Mode high-availability (HA) pair and convert the nodes into standalone systems. Each step is a necessary component of the overall process:

1. cf disable: This command disables the cluster failover mechanism, which is the first logical step in separating the nodes.

2. Unlicense cluster: The cluster license key enables HA functionality and must be removed to revert to a standalone configuration.

3. Remove partner entries from /etc/rc: The /etc/rc file contains boot-time network configurations. Partner-specific interface configurations must be removed to prevent errors when the node boots without its partner.

4. Halt and clear partner-sysid: The partner-sysid is a critical boot environment variable that identifies the HA partner. It must be cleared on both nodes to break the cluster relationship at the hardware identity level. This is done from the boot loader prompt after halting the system.

5. Remove cluster interconnect: The physical interconnect (cables and/or card) provides the dedicated, high-speed link for the HA heartbeat and NVRAM mirroring. It must be physically disconnected or removed to sever the hardware link.

6. Perform on partner node: Since an HA pair consists of two nodes, the entire procedure must be replicated on the partner to complete the separation.

While the exact sequence of these steps can vary slightly in practice, the set of actions listed is fundamentally correct and necessary to achieve the goal.

The alternative, "False," is incorrect because the list accurately enumerates the required tasks for decommissioning a 7-Mode HA pair. To claim the statement is false would imply that one or more of these steps are unnecessary or that the overall procedure is invalid, which is not the case according to official documentation.

7-Mode System Administration Guide

Reference: Part 5

Chapter 22

"High-availability configuration and management

" section "Converting an HA pair to two standalone storage systems."

Content: This guide explicitly details the procedure. It instructs the administrator to: 1. cf disable on both nodes. 2. Halt both nodes. 3. At the LOADER prompt

set the partner system ID to null (setenv partner-sysid ""). 4. Disconnect the cluster interconnect cables. 5. Boot the nodes individually. 6. Edit the /etc/rc file to remove partner interface information. 7. Use the license delete command to remove the cluster license. This source validates that all steps mentioned in the question are required components of the official procedure.

High-Availability Configuration Guide

Reference: Chapter 5

"Disabling a high-availability configuration

" section "Converting an HA pair to two standalone systems."

Content: This guide for an earlier version of ONTAP provides a nearly identical procedure

confirming the long-standing nature of these steps. It lists the following actions: disabling cluster failover (cf disable)

halting the nodes

clearing the partner-sysid at the boot prompt

disconnecting the interconnect

booting the systems

editing the /etc/rc file

and removing the cluster license. This corroborates that the actions in the question are correct and necessary.
