Controller Module Installation
Instructions
This document details procedures for installing a controller module in HP StorageWorks array enclosures.
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 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.

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 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).
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 this
illustration. Port and LED information is not included.
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
OK
Fault/Service Required
• 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
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
nl
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.
