About this document

•The Storage Management Utility (SMU) and the

Command Line Interface (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 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.

locations:

location

location

NOTE: Illustrations in this document show

generic representations of modules and

enclosures. For clarity, only relevant details are

shown; port and LED information is not included.

Procedures are the same for all modules shipped

with this document.

Enabling Partner Firmware Update

(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 navigation tree

and then select Configuration > Advanced Settings >

Firmware. If needed, check the box and click Apply.

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 the screws 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).

NOTE: The illustration is for reference only. In

a single-controller system, remove the air

management module from module A, top

location.

Installing the new controller 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).

Press firmly on the top-center of the module to

facilitate insertion, ensuring that the module is

well seated and flush with the chassis.

2. Rotate the latches upward to engage the module

with the internal connector (2) and then, turn the

thumbscrews finger-tight (3).

NOTE: The illustration is for reference

only. In a single-controller system, insert the

controller module into module A, top

location.

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.

3. 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

After installing the controller module, check the module

status. For LED descriptions, see Table 1.

If the Fault/Service Required LED is amber, the module

is not online and likely failed its self-test. Remove and

reinstall the module.

If the problem is not resolved, refer to your array

troubleshooting information.

Table 1 LED descriptions

DescriptionModule LED

FRU OK •Solid Green = Module is operating

normally

•Blink = System is starting up

•Off = Module is NOT operating

normally

Fault/Service Required •Solid Amber = Fault condition

•Blinking Amber =

Hardware-controlled power-up or

cache flush/restore error

•Off = No fault conditions

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.

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.
