3.2. Replace controller in duplex configuration
You can replace a controller canister in a duplex (two-controller) configuration,
for the following controller shelves:
•
DE6000H (2U24) controller shelf
•
DE6000H (4U60) controller shelf
•
DE6000F flash array
About this task
Each controller canister contains a controller card, a battery, and an optional host interface card
(HIC). When you replace a controller canister, you must remove the battery and HIC, if one is
installed, from the original controller canister, and then install them in the replacement controller
canister. NOTE: This task is only for storage arrays with two controllers (duplex configuration).
This procedure applies to IOM12 and IOM12B drive shelves.
This procedure is for like-for-like shelf IOM hot-swaps or replacements. This
means you can only replace an IOM12 module with another IOM12 module or
replace an IOM12B module with another IOM12B module. (Your shelf can have
two IOM12 modules or have two IOM12B modules.)
What you’ll need
•
A replacement controller canister with the same part number as the controller canister you are
replacing. (See step 1 to verify the part number.)
•
An ESD wristband, or you have taken other antistatic precautions.
•
#1 Phillips screwdriver.
•
Labels to identify each cable that is connected to the controller canister.
•
A management station with a browser that can access ThinkSystem System Manager for the
controller. (To open the System Manager interface, point the browser to the controller’s domain
name or IP address.)
3.2.1. Step 1: Prepare to replace controller (duplex)
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. If the
controller is still online, you must take it offline.
Steps
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.
