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.
