About this document
•Illustrations in this document may show modules or
a chassis that differ from your devices.
•The Storage Management Utility (SMU) and the
Command Line Interface (CLI) can be used to
manage the storage. Tasks in this document
demonstrate using the SMU.
•For the latest product documentation, see the HP
website at http://www.hp.com/support/manuals.
•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

herein. To obtain a copy of the warranty for this

Before you begin
Observe the following:
CAUTION: 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.
Do the following before beginning these procedures:
•Schedule a maintenance window that will include
time for shutdown, sixty minutes of replacement
work, and restart.
•Verify that there is a recent backup of the system.
•Record system settings.
•Label all cables.
•Prepare a large, stable work surface.
Procedural overview
Replacing a failed chassis includes the following key
steps:
1. Removing drive and drive blank modules from the
failed chassis.
2. Removing the failed chassis from the rack.
3. Moving side brackets to the replacement chassis.
4. Moving power and cooling, controller, I/O, and
air management modules to the replacement
chassis.
5. Installing the replacement chassis in the rack.
6. Installing drive or drive blank modules in the
replacement chassis.
7. Completing the process and verifying proper
operation.
Preparing for the replacement
1. If the controller enclosure or drive enclosure chassis
is operational, do the following to shutdown the
storage system:
a. Stop all I/O to the storage system that includes
the failed chassis.
b. Shutdown all array controllers in the system.
To shutdown a controller using the SMU, select
the array in the navigation tree and then select
Tools>Shutdown or Restart Controller. After the
controller is shut down, the blue OK to Remove
LED on the controller illuminates.
2. Turn off power and cooling module switches (if
present).
3. Make sure the cables are clearly labelled and then
disconnect the cables, including the power cords,
from the modules.
IMPORTANT: Use caution when handling Fibre
Channel cables:
•Touching the end of a Fibre Channel cable
either damages the cable or causes
performance problems, including intermittent
difficulties accessing the storage.
•When a Fibre Channel cable or port is not
connected, install protective covers on the
ends of the cable or in the device port.
Removing drive and drive blank modules
from the failed chassis
CAUTION:
•These procedures require that all drives be
removed from the failed chassis and then
installed in the replacement chassis.
•Because drives are heavy, HP recommends
removing drives prior to moving the chassis.
If this is not possible, two or more people are
required to lift the chassis.
•Remove the drives after confirming that all
internal movement has halted.
•As a best practice, remove the drive and
drive blank modules in bay-number sequence
and organize them on your work surface in
the same sequence. This helps ensure that
you reinstall the modules in the same bay
number from which they were removed.
1. Press and slide the release latch button to release
the latch handle (1).
2. Rotate out the latch handle to disengage the module
from the internal connector (2).
3. Pull the module straight out of the chassis (3).
Removing the failed chassis from the rack
1. Remove the ear bezels by grasping each bezel
firmly and pulling until the bezel separates from the
ball nuts on the chassis ear.
2. Remove retaining screws securing the front and rear
of the chassis to the rack and rails.
3. Remove the chassis from the rack.
4. Place the failed chassis on the work surface near
the replacement chassis.

Moving side brackets to the replacement
chassis
1. Remove the side bracket from each side of the failed
chassis.
2. Attach the side bracket to each side of the
replacement chassis.
Moving power and cooling modules to the
replacement chassis
1. Remove the power and cooling modules from the
failed chassis:
a. Turn the thumbscrew until the screw disengages
from the module (1).
b. Rotate the latch downward to disconnect the
module from the internal connector (2).
c. Pull the module straight out of the chassis (3).
2. Install power and cooling modules in the
replacement chassis.
With the latch in the open position, slide the module
into the chassis as far as it will go and rotate the
latch upward to engage the module with the internal
connector. Then, turn the thumbscrew finger-tight.
Moving controller, I/O, or air management
modules to the replacement chassis
IMPORTANT: Modules must be reinstalled in the
same bays from which they were removed.
Installing a module in a bay other than the one
from which it was removed may result in loss of
access to the storage.
1. Remove the modules from the failed chassis:
a. 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).
b. Pull the module straight out of the chassis (3).
2. Install the modules in the replacement chassis.
With the latches in the open position, slide the
module into the chassis as far as it will go. Rotate
the latches upward to engage the module with the
internal connector, and then turn the thumbscrews
finger-tight.
Installing the replacement chassis in the rack
1. Support the bottom of the chassis and place the
chassis in the rack.
2. Secure the chassis to the rack.
3. Install the ear bezels by aligning each bezel with
the ball nuts on the chassis ear and pressing firmly
until the bezel clicks in place.
Installing drive or drive blank modules in the
replacement chassis
IMPORTANT: Reinstall each drive or drive blank
module in the same bay number from which it
was removed.
1. With the latch in the open position, slide the module
into the drive slot as far as it will go (1).
2. Rotate the latch closed until it clicks (2).
Completing the process
1. Reconnect data cables to the original cabling
configuration. As needed, connect cables:
•Between cascaded drive enclosures.
•Between the first and last drive enclosure and
the controller enclosure.
•Between the controller enclosure and the host.
2. Reconnect power cords to the devices.
3. Turn on power and cooling module switches (if
present).
4. Restart system devices in the following sequence,
allowing time for each device to complete its Power
On Self Tests (POST) before proceeding:
a. Drive enclosures
b. Controller enclosures
c. Hosts
5. Perform a rescan to force a fresh discovery of all
drive enclosures connected to the controller
enclosure. This step clears the internal SAS layout
information and reassigns enclosure IDs based on
the cabling sequence. This ensures that the
enclosures are numbered correctly.
To perform a rescan using the SMU, in the
Configuration View panel, right-click the system and
select Tools>Rescan Disk Channels. Then, click
Rescan.
Verifying operation
View LEDs on the front of the chassis and on each
module. For detailed LED information, see the user guide
for your model controller enclosure or drive enclosure.
•Drive modules: Verify that the Online/Activity LED
(bottom LED) is green.
•Power and cooling modules: Verify that the Input
Power Source Good LED (top LED) is on.
•Controller modules and I/O modules: Verify that
the OK LED is on, indicating that the module has
completed initializing and is online.
•Chassis front panel: Verify that the Heartbeat LED
is green and that the Fault LED is off.
Returning failed items
In materials shipped with the replacement, HP specifies
if the failed component must be returned. Follow the
provided instructions.
