About this document

•Illustrations in this document may show modules or an enclosure that

differ slightly from the devices in your environment.

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

face (CLI) can be used to manage the storage 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.

•Warranties for HP products and services are set forth in the express

warranty statements accompanying such products and services.

Nothing herein should be construed as constituting an additional

warranty. HP shall not be liable for technical or editorial errors or

omissions contained herein. To obtain a copy of the warranty for

this product, see the warranty information website: http://

www.hp.com/ go/storagewarranty.

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 ready to install a replacement.

•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 two controllers are installed in an enclosure, they must

be the same model. Mixing controller types in the same

enclosure is not supported.

NOTE:

Port-colored (purple) latches on modules mean the module is

hot-swappable. It can be replaced without having to power

down the system.

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 the array in

the navigation tree and then select Tools>Advanced Settings>Firmware.

If needed, check the box and click Apply to enable the new setting.

NOTE:

If the Tools>Advanced Settings>Firmware page is not

accessible, log in as an Advanced or Diagnostic level user.

Removing the air management module

IMPORTANT:

Remove the air management module from the bottom bay only

when installing an optional second module.

1. Turn the thumbscrews until they disengage from the module (1) and

rotate both latches downward to disengage the module from the

internal connector (2).

2. Pull the module straight out of the enclosure (3).

Installing the new module

IMPORTANT:

When installing modules in a new system, install the first module

in the top bay.

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).

NOTE:

For clarity, only relevant details are shown in these

illustrations. Port and LED information is not included.

After installing a second controller in an operational single-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.

Verifying proper operation

Examine module status as indicated in Table 1.

If the Fault LED is amber, the module has not gone online and likely

failed its self-test. Remove and reinstall the module.

Table 1 LED descriptions

DescriptionModule LED

•Solid Green = Module is operating

normally

•Blink = System is starting up

•Off = Module is NOT operating nor-

mally

•Solid Amber = Fault condition

•Blinking Amber = Hardware-controlled

power-up or cache flush/restore error

•Off = No fault conditions

Fault/Service Required

Verifying the firmware version

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

all controllers in the controller enclosure. Go to the website for your

enclosure model and, if newer firmware is available, download the

firmware from the Web and install this latest version on the controller(s).

For more information on firmware updates, see the storage enclosure

user guide.

Upgrading from single-controllers to

dual-controllers

As appropriate for your environment, connect cables from this new

module to the host or other disk enclosures. For more information about

cabling and configuring the system, see the user guide.
