Controllers
A controller consists of a board, firmware, and software. It controls the drives and implements the System
Manager functions. This section describes how to replace a single controller or both controllers in your AB6100
controller shelf.
Overview and requirements
Before you replace a controller, you need to be aware of certain requirements and considerations.
Requirements for replacing a controller
If you plan to replace a controller, keep the following requirements in mind.
Requirements for replacing a failed controller
• You must have a replacement controller canister with the same part number as the controller canister you
are replacing.
• You have an ESD wristband, or you have taken other antistatic precautions.
• You must use labels to identify each cable that is connected to the controller canister.
• You must have a #1 Phillips screwdriver.
• You must have installed SANtricity System Manager on a management station, so you can use the storage
array's command line interface (CLI).
If this software has not yet been installed, follow the instructions in the Linux express configuration,
Windows express configuration, or VMware express configuration to download and install it.
You can replace a controller canister while your storage array is powered on and performing host I/O
operations, as long as the following conditions are true:
• The second controller canister in the shelf has Optimal status.
• The OK to remove field in the Details area of the Recovery Guru in SANtricity System Manager displays Yes,
indicating that it is safe to remove this component.
This section describes how to replace a controller canister in the following controller shelves:
• AB6100 controller shelf
Replace controller
This section describes the steps to replace a single controller in your AB6100 controller shelf.
Before you begin
When you replace a failed controller canister, you must remove the battery, power supply, DIMMs, fans, 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.
Prepare to replace controller
When a controller canister fails, you must replace it. You prepare to replace a controller canister by verifying
that the replacement controller canister has the correct FRU part number, backing up the configuration, and
collecting support data.
11

|Controllers|
Procedure
1. Unpack the new controller canister, and set it on a flat, static-free surface.
Save the packing materials to use when shipping the failed controller canister.
2. Locate the MAC address and FRU part number labels on the back of the controller canister.
3. From SANtricity System Manager, locate the replacement part number for the controller canister you are
replacing.
When a controller has a fault and needs to be replaced, the replacement part number is displayed in the
Details area of the Recovery Guru. If you need to find this number manually, follow these steps:
a) Select Hardware.
b) Locate the controller shelf, which is marked with the controller icon .

attempt this procedure. In addition, if the failed controller canister includes a host interface card
(HIC), you must install that HIC into the new controller canister. The presence of mismatched
controllers or HICs causes the new controller to lock down when you bring it online.
5. Back up the storage array's configuration database.
If a problem occurs when you remove a controller, you can use the saved file to restore your configuration.
a) In System Manager, navigate to the support page.
b) Select the Support Center tab.
