How to setup one Dell EMC AX4-5 Dual Controller System from two AX4-5 with Single Controllers
Hi,
A few years ago we bought two Dell EMC AX4-5 Systems with single controller. Meanwhile the Support ended. The performance of a Single Controller System is very slow. A new Hard disk cost around 1000€ by Dell-Customer-Support. We decide to use only one chassis, but with 2 controllers (one from the second system).
The Problem is our system don't detect the second controller we took from the other Single-Controller System. We couldn’t find any manual to set the DIP-Switches on the controller. Does anyone know how to setup a Dual-Controller-System with components from two single Controller AX4-5 Systems?
Regards,
Klaus Kupferschmid

This is what I was able to find about converting a single SP to a dual SP on the AX4. I have not found the enabler as yet - this would probably need to be purchased from EMC.
Single-SP to dual-SP upgrades
1. Install the Dual-SP enabler using Navisphere Express and wait for installation to complete. Verify using NaviSecCli ndu -status.
2. Destroy domain and security information using the Setup page option.
3. Install SP B (with the storage system powered up).
4. Wait for SP B to boot and stabilize. The SP fault LED will become solid green.
5. Use the Navisphere Initialization Tool UI to discover the storage system. Repeat until both SPs are displayed when next is clicked.
6. Use the Initialization Tool UI to set up the storage system.
7. Wait for both SPs to reboot (to pick up new IP information)
Notes:
This procedure may take 30-60 minutes to complete.
During this procedure, you may see some temporary alerts including 0x7428, 0x743a, 0x720f, 0x7403 or 0x7404. After the upgrade completes, all alerts will eventually disappear.
An optional second SPS can be added after Step 7. The single SP will not use the SPS so the second SPS is always new when the second SP comes up.
