Installing the new controllers
When you upgrade by moving storage, you begin by installing the new controllers and attaching power,
console, and network connections to the new controllers.
Step 1. If needed, install any adapters in the new controllers, following the instructions in the appropriate
adapter installation guide.
Step 2. Install the new controllers, following the Installation and Setup Instructions for the platform. Do not
attach disk selves from the original controllers to the new controllers at this point.
Step 3. Attach power and console connections to the new controllers, following the Installation and Setup
Instructions for the platform.
Step 4. Attach the network cables.
Step 5. Transfer all remaining cables from the original controller to the corresponding ports on the new
controller. This includes Fibre Channel or other external disk shelf cables, and Ethernet cables.
Setting up the new controllers
During the process of upgrading by moving storage, you power on the new controllers, boot the software
image, and configure the new controllers.
Step 1. Turn on the power to the first new controller, and then immediately press Ctrl-C at the console
terminal to access the boot environment prompt (also called the LOADER prompt).If you are
upgrading to a system with both controllers in the same chassis, the other controller also reboots.
You can disregard booting the other controller for now.
Step 2. If the new controller has a single-chassis configuration (with controllers in the same chassis):
a. Switch the console cable from the current new controller to the other new controller.
