About this document

This document details procedures for replacing a failed controller

module in an HP StorageWorks 2012fc Modular Smart Array.

NOTE: Make sure you obtain the latest version of these

instructions 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 than

10 seconds elapse between inserting the controller into a slot and

fully latching it in place. Failing to do so might cause the controller

to fail. If it is not latched within 10 seconds, remove the controller

from the slot and repeat the process.

Parts can be damaged by electrostatic discharge. Use proper

anti-static protection:

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

•Wear an ESD wrist strap grounded to an unpainted surface of

the chassis.

•If an ESD wrist strap is unavailable, touch an unpainted surface

of the chassis before handling the component.

•Never touch connector pins.

Using the Storage Management Utility (SMU), save your

configuration settings to a file for backup.

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

File.

2. Click Save Configuration File.

In a dual-controller configuration, the storage system’s Partner

Firmware Upgrade option is enabled by default, so when you

upgrade a controller the system automatically ensures that both

controllers have the most recent version.

Use SMU to verify that Partner Firmware Update is enabled.

1. Select Monitor > Status > Advanced Settings > Misc

Configuration to view the current setting.

2. If Partner Firmware Upgrade is disabled, select Manage >

General Config > System Configuration, and then set Partner

Firmware Upgrade to Enabled.

Verifying component failure

Use 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 module

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

controller is online by selecting Monitor > Status > Status

Summary.

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 that

the controller can be removed safely.

3. Illuminate the UID (Unit Identification) LED of the enclosure that

contains the controller module to remove.

a. Select Manage > General Config > Enclosure Management.

b. Click Illuminate Locator LED.

4. Locate the enclosure whose UID LED (front right ear) is blue, and

within it, the controller module whose OK to Remove LED is blue.

5. Disconnect any SAS cables that connect the controller to a drive

enclosure.

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

controller.

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

midplane.

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

enclosure.

Installing the controller module

NOTE: You can install a controller into an enclosure that is

powered 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 the

thumbscrews finger-tight.

4. Reconnect the SAS cables.

IMPORTANT: In a dual-controller configuration, if the

firmware versions differ between the two controllers, Partner

Firmware Upgrade brings the older firmware to the later firmware

level.

Verifying component replacement

After replacing the controller, check that the OK LED (back)

illuminates green, indicating that the controller has completed

initializing 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 gone

online and likely failed its self-test. Put the module online by

following the steps to restart a controller or by checking the event

log for errors.
