P2000 G3 Modular Smart Array
Controller Module Replacement
Instructions

This document details procedures for replacing a failed
controller module in an HP StorageWorks P2000 G3
MSA system.

About this document

• Illustrations in this document show generic representations of modules

and enclosures; procedures are the same for all modules shipped
with this document.

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

face (CLI) can be used to manage the enclosure. 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:

• 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

Before replacing the module, look at the event log, software management
utilities, and device LEDs, to confirm that the module has failed.

Table 1 LED descriptions

DescriptionModule LED

• Solid Green = Module is operating

normally

OK LED

• Blink = System is starting up

• Off = Module is NOT operating nor-

mally

• For information about all hosts (IDs and names):

In the Configuration View panel, select Hosts and then click View >
Overview.

• For information about a specific host (IDs, names, and mappings):

In the Configuration View panel, expand the display under Hosts
and then select a specific host.

• For overview information, including host IDs and nicknames, in

the main section of the screen, select Host. Scroll down to see
details.

• For mapping information, in the main section of the screen, select

Maps. Scroll down to see details.

Enabling Partner Firmware Update

nl

(dual-controller configurations only)

In a dual-controller configuration, the Partner Firmware Update option
ensures that both controllers have the most recent version. HP
recommends enabling this feature.

To view or change the current Partner Firmware Update setting, select
the system in the Configuration View panel and then select Configuration

> Advanced Settings > Firmware. If needed, check the box and click
Apply.

Removing the failed module

• Solid Amber = Fault condition

Fault/Service Required
LED

• Blinking Amber = Hardware-controlled

power-up or cache flush/restore error

• Off = No fault conditions

Recording configuration settings

As a best practice, record system settings before replacing a controller
module.

To obtain key settings using the SMU, in the Configuration View panel,
select the system and then click the following menu options:

• For date, time, and NTP settings:

Configuration > System Settings > Date, Time

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

Configuration > System Settings > System Information

• For user information:

Configuration > Users > Modify User

• For email notification settings:

Configuration > Services > Email Notification

• For SNMP notification settings:

Configuration > Services > SNMP Notification

• For information about scheduled tasks:

View > Overview

In the main section of the page, select Schedules. Scroll down to see
details.

IMPORTANT:

• In a single-controller configuration, if transporting the Com-

pactFlash to a new controller, remove the controller only after
the cache is copied to CompactFlash, which is indicated by
the Cache Status LED being off.

• 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 operation­al enclosure.

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

a. Select the system in the Configuration View panel and then

select Tools > Shut Down or Restart Controller.

b. Set the following options and then click OK:

• Operation=Shut down

• Controller Type=Storage

• Controller=A or B

The blue OK to Remove LED on the controller illuminates to
indicate that the controller can be safely removed.

2. Locate the enclosure in which the controller module OK to Remove

LED is blue.

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

from the enclosure.

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

facilitate reconnection.
