 About this documentThis document details procedures for replacing a failed controllermodule in an HP StorageWorks 2012fc Modular Smart Array.

NOTE: Make sure you obtain the latest version of theseinstructions from http://www.hp.com/go/msa. Select MSA SAN Arrays, select your product, and go to Support.

Before you begin

CAUTION:  When replacing a controller, ensure that less than10 seconds elapse between inserting the controller into a slot andfully latching it in place. Failing to do so might cause the controllerto fail. If it is not latched within 10 seconds, remove the controllerfrom the slot and repeat the process.

Parts can be damaged by electrostatic discharge. Use properanti-static protection:

• Keep the replacement component in the ESD bag until needed.

•  Wear an ESD wrist strap grounded to an unpainted surface ofthe chassis.

• If an ESD wrist strap is unavailable, touch an unpainted surfaceof the chassis before handling the component.

• Never touch connector pins.

Using the Storage Management Utility (SMU), save yourconfiguration settings to a file for backup.

1. Select Manage > Utilities > Configuration Utilities > Save ConfigFile.

2. Click Save Configuration File.

In a dual-controller configuration, the storage system’s PartnerFirmware Upgrade option is enabled by default, so when you

upgrade a controller the system automatically ensures that bothcontrollers have the most recent version.

Use SMU to verify that Partner Firmware Update is enabled.

1. Select Monitor > Status > Advanced Settings > MiscConfiguration to view the current setting.

2. If Partner Firmware Upgrade is disabled, select Manage >General Config > System Configuration, and then set PartnerFirmware Upgrade to Enabled.

 Verifying component failureUse the following methods to verify component failure:

• Check Fault/Service Required LED (back):• Amber = Fault condition

• Check that the OK LED (back) is off.

• Check the event log for errors.

Removing the controller module1. In a dual-controller configuration, verify that the partner

controller is online by selecting Monitor > Status > StatusSummary.

2. Shut down the failed controller.

a. Select Manage > Restart System > Shut Down/Restart, and

select a controller option.b. Click Shut Down and click OK.

The blue OK to Remove LED (back) illuminates to indicate thatthe controller can be removed safely.

. Illuminate the UID (Unit Identification) LED of the enclosure thatcontains the controller module to remove.

a. Select Manage > General Config > Enclosure Management.

b. Click Illuminate Locator LED.

. Locate the enclosure whose UID LED (front right ear) is blue, andwithin it, the controller module whose OK to Remove LED is blue.

. Disconnect any SAS cables that connect the controller to a driveenclosure.

. Turn the thumbscrews (2) until the screws disengage from thecontroller.

. Press both latches downward to disconnect the module from themidplane.

. Pull outward on the latches to slide the module out of theenclosure.

Installing the controller module

NOTE: You can install a controller into an enclosure that ispowered on.

1. Loosen the controller’s thumbscrews; press the latches downward

2. Slide the controller into the enclosure as far as it will go (1).

3. Press the latches upward to engage the controller (2); turn thethumbscrews finger-tight.

4. Reconnect the SAS cables.

IMPORTANT: In a dual-controller configuration, if thefirmware versions differ between the two controllers, PartnerFirmware Upgrade brings the older firmware to the later firmwarelevel.

 Verifying component replacement After replacing the controller, check that the OK LED (back)illuminates green, indicating that the controller has completedinitializing and is online.

If the enclosure’s UID is on, use SMU to turn it off.

1. Select Manage > General Config > Enclosure Management.

2. Click Turn Off Locator LED.

If the Fault/Service Required LED is amber, the module has not goneonline and likely failed its self-test. Put the module online byfollowing the steps to restart a controller or by checking the eventlog for errors.
