About this document

•Illustrations in this document may show a controller module with a

connection interface that differs from your controller module. Replace-

ment procedures are the same for all MSA2000 controller modules.

•The Storage Management Utility (SMU) and the Command Line Inter-

face (CLI) can be used to manage MSA2000–family enclosures.

Tasks in this document demonstrate using the SMU.

•For the latest product documentation, see the HP website at http://

www.hp.com/support/manuals. Under the storage banner, navigate

to the page for your storage enclosure.

Before you begin

Observe the following:

CAUTION:

•When replacing a controller in an operational controller en-

closure, ensure that less than 10 seconds elapse between in-

serting 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.

•Removing a module from an operational enclosure significantly

changes air flow within the enclosure. Openings must be

populated for the enclosure to cool properly. Leave modules

in the enclosure until a replacement is available.

•Parts can be damaged by electrostatic discharge; use proper

anti-static protection. Keep parts in electrostatic containers

until needed and ensure you are properly grounded when

touching static-sensitive components.

IMPORTANT:

When replacing both controllers in an operational enclosure,

do as follows:

1. Replace one controller as detailed in these instructions.

2. Wait 30 minutes. This pause ensures that the two controllers

and their ownership of the vdisks have enough time to fully

stabilize.

3. Examine system status and event logs to ensure that the system

is stable.

4. Replace the other controller as detailed in these instructions.

IMPORTANT:

When two controllers are installed in an enclosure, they must

be the same model. Mixing controller types in the same

enclosure is not supported.

NOTE:

To reduce impact on system performance, perform all

maintenance tasks during periods of low system activity or

during a system maintenance window.

Verifying module failure

Use the following methods to verify failure:

•Check the Fault/Service Required LED (back):

•Amber = Fault condition

•Check that the OK LED (back) is off.

•Check the event log for errors.

Recording configuration settings

IMPORTANT:

When replacing the controller in slot A, configuration settings

may be reset to the values of the new controller. (This does not

occur when replacing the controller in slot B.)

To obtain key settings using the SMU, in the Configuration View panel,

right click the system and do the following:

•For system information (name, contact, location, and description):

Manage > General Config > System Information

•For user information:

Manage > General Config > User Configuration

•For date, time, and NTP settings:

Manage > General Config > Set Date/Time

•For email and SNMP notification settings:

Manage > Event Notification

•Volume mapping information:

Manage > Volume Management > Volume Mapping > Map Hosts To

Volume

•For information about scheduled tasks:

Manage > Scheduler

•For host IDs and nicknames:

Manage > Volume Management > Volume Mapping > Manage Host

List

Enabling Partner Firmware Upgrade

(dual-controller configurations only)

In a dual-controller configuration, the Partner Firmware Upgrade option

ensures that both controllers have the most recent version. HP

recommends enabling this feature.

To see the current Partner Firmware Upgrade setting, select Monitor >

Status > Advanced Settings > Misc Configuration.

If Partner Firmware Upgrade is disabled, select Manage > General Config

> System Configuration, and then set Partner Firmware Upgrade to

Enabled.

NOTE:

If the Monitor > Status > Advanced Settings > Misc

Configuration page is not accessible, sign in to the SMU as an

Advanced or Diagnostic level user.

Removing the failed module

IMPORTANT:

•In a single-controller environment, I/O must be stopped and

the enclosure must be powered off prior to the replacement.

•In a dual-controller environment, if the failed controller is first

shut down, the controller may be hot-replaced in an operation-

al enclosure.

1. In a dual-controller configuration, shut down the failed controller:

a. Select the system in the navigation tree and then 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.

2. 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.

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

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

4. In a single-controller environment, stop all I/O and remove power

from the enclosure.

5. Disconnect cables connected to the module. Label each cable to

facilitate reconnection.

6. Turn the thumbscrews until the screws disengage from the module.

7. Rotate both latches downward to disengage the module from the

internal connector.

8. Pull the module straight out of the enclosure.

Installing the new module

1. With the latches in the open position, slide the module into the

enclosure as far as it will go (1). If necessary, press lightly on the

top-center of the module to facilitate insertion.

2. Rotate the latches upward to engage the module with the internal

connector (2) and then, turn the thumbscrews finger-tight (3).

3. Reconnect the cables.

NOTE:

After installing a controller in an operational,

dual-controller system, the new controller automatically

begins to initialize. If the firmware versions differ

between the two controllers, Partner Firmware Upgrade

feature brings the older firmware to the later firmware

level.

4. In operational systems, if additional hardware components, such

as a second controller, need replacing or installing, wait 30 minutes

before proceeding with those procedures. This time frame ensures

that the controller(s) and their ownership of vdisks are fully stabilized.

Verifying proper operation

Examine module status by checking that the OK LED (back) illuminates

green, indicating that the controller has completed initializing and is

online.

If the Fault/Service Required LED is amber, the module has not gone

online and likely failed its self-test. Check the event log for errors and

then restart the controller to put the module online. To restart a controller,

do the following: In the Configuration View panel, right-click the local

system and select Manage > Restart System > Shut Down/Restart, and

select the appropriate options.

If the enclosure UID is on, do the following to turn it off: Select Manage

> General Config > Enclosure Management. Then, click Turn Off Locator

LED.

Verifying configuration settings

After replacing a controller, verify that system configuration settings are

set properly for your environment. Repeat the commands shown in

“Recording configuration settings”on page 2 and compare the current

values with those recorded before the installation. If necessary, change

the settings to their previous values. For more information, see online

help or the HP StorageWorks 2000 Family Modular Smart Array

reference guide.

Verifying the firmware version

After installing a controller, verify that the latest firmware is installed on

all controllers in the enclosure. Go to the HP Support website at

http://www.hp.com/support and navigate to the page for your

enclosure. If newer firmware is available, download the firmware from

the Web to your local system and install that latest version on the

controllers. For more information on firmware updates, see the enclosure

user guide.

Returning the failed items

In materials shipped with the replacement, HP specifies whether the

failed component must be returned. Follow the provided instructions.
