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 docu-

ment 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.

The following illustration shows controller module locations:

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:

For clarity, only relevant details are shown in this

illustration. Port and LED information is not included.

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.

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

Examine module status as indicated in Table 1.

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.

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 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.
