open the System Manager interface, point the browser to the controller’s domain name or IP address.)
Optionally, you can use the command line interface (CLI) to perform some of the procedures. If you do not

◦ For SANtricity System Manager (version 11.60 and above) — Download the CLI package (zip file)
from System Manager. Go to Settings
› System › Add-ons › Command Line Interface. You can then
issue CLI commands from an operating system prompt, such as the DOS C: prompt.
◦ For SANtricity Storage Manager/Enterprise Management Window (EMW) — Follow the instructions
in the express guide to download and install the software. You can run CLI commands from the EMW
by selecting Tools
› Execute Script.
Requirements for replacing controller
When you replace a failed controller canister, you must remove the battery and HIC, if one is installed, from the
original controller canister, and install them in the replacement controller canister.
You can determine if you have a failed controller canister in two ways:
• The Recovery Guru in SANtricity System Manager directs you to replace the controller canister.
• The amber Attention LED on the controller canister is on, indicating that the controller has a fault.

Before you replace a controller, you must have:

• An ESD wristband, or you have taken other antistatic precautions.
• Labels to identify each cable that is connected to the controller canister.
• #1 Phillips screwdriver.
• A management station with a browser that can access SANtricity System Manager for the controller. (To
open the System Manager interface, point the browser to the controller’s domain name or IP address.)
