Ensure that a known, good backup is available. 2. Schedule a maintenance window. 3. From the servers, stop all access to the MSA. 4. Power off the MSA and disconnect the power cords to prevent any new access. Dual-controller configurations If one of the two controllers has failed, you may remove the failed controller for servicing at any time. If both controllers are operational, but one or both of them need servicing, you can schedule a maintenance window to perform the service, or do the following to disable and service the standby controller while operating in a non-redundant mode from the active controller. 1. Access the management utility for your MSA: Table 2 Available management utilities MSA model MSA1000 MSA1500 cs MSA1510i Available management utilities Command Line Interface Array Configuration Utility, Command Line Interface Storage Management Utility, Command Line Interface IMPORTANT: During this procedure, because you disable the controller being removed, you temporarily operate in a non-redundant mode. 2. In your chosen management utility, disable the controller to be removed. For details, see online help or your user documentation. 3. Wait for the following LCD message to be displayed before removing the controller: 204 ARRAY CONTROLLER DISABLED IMPORTANT: If an operational controller is removed from the chassis without first being disabled, the active controller might halt. To clear this fault condition, power cycle the MSA. Replacing the controller/components Step 1: Remove the controller 1. Press the controller thumb latch and rotate the latch handle out (1). 2. Pull the controller straight out of the chassis (2). 1 2 15181 Step 2: Remove the cache module (if applicable) NOTE: If you are not replacing controller cache modules, proceed to Step 3. IMPORTANT: Replacement controllers include a new cache module. Remove this new module from the replacement controller and replace it with the cache module from the failed controller. Using the same cache module completes disk writes trapped in the cache. IMPORTANT: When replacing a controller cache module in a dual-controller configuration, the memory size of the new module must be identical to that of the already installed module. NOTE: The controller in the following illustration has been rotated to show the side and rear of the controller.
