Removing an HA Association
You can remove the association between two SonicWall Security Appliances on MySonicWall at any time. You might need to remove an existing HA association if you replace a Security Appliance or reconfigure your network. For example, if one of your SonicWall Security Appliances fails and you need to replace it, or you might need to switch the HA Primary Security Appliance with the Secondary, or HA Secondary, unit after a network reconfiguration. In either case, you must first remove the existing HA association, and then create a new association that uses a new Security Appliance or changes the parent-child relationship of the two units (see Replacing a SonicWall Security Appliance).
To remove the association between two registered SonicWall Security Appliances:
- Log in to MySonicWall.
- In the left navigation bar, navigate to My Workspace > Tenant Products.
- Scroll down to find the secondary Security Appliance from which you want to remove associations. Click the serial number.
- On the Products Details page, scroll down to the Parent Products section, just below the Associated Products section.
- Under Parent Products, to remove the association for this Security Appliance:
- Click Remove under ACTIONS.
- Wait for the page to reload.
- Scroll down.
- Click Remove again.
