2240-4 acp ontap 8.1.4 7-mode assigns IP address in the same subnet as production data

We are getting the following error on one of our HA partners:

Fri Dec 22 00:10:00 PST [FILER:net.if.mgmt.sameSubnet:warning]: ifconfig: IP address '192.168.2.21' configured on dedicated management port 'e0P' is on the same subnet as IP address '192.168.2.161' configured on data port ifgrp1-1. Management IP addresses must be on dedicated management subnets.

Well, I run acpadmin configure on the Filer and choose a private subnet 192.168.0.0 with the mask of 255.255.252.0, and it automatically assigns that IP address for ACP. How do I prevent it from choosing an IP address that's in the same subnet as the data port?

This EMS error message is a false positive message.

The ACP network is in a private IP space. It cannot conflict with any other IP interface configured on the system

The defaults should be used: 192.168.0.0 as the ACP domain, and 255.255.252.0 subnet mask.

Run "acpadmin configure", if necessary.

You can see this if you run:

> ipspace list

Cool! Thank you for confirming that.
