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. Under the
storage banner, navigate to the page for your device.
•Warranties for HP products and services are set forth
in the express warranty statements accompanying such
products and services. Nothing herein should be

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 known, good 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, or 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.
Preparing for the replacement
1. If the controller enclosure or drive enclosure chassis is
operational, do the following:
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 all cables are clearly labelled and then
disconnect all cables, including 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.
•Because drives are heavy, HP recommends
removing drives prior to moving the chassis. If
this is not possible, two or more people are
required.
•Remove drives only after confirming that all
internal movement has halted.
•As a best practice, remove drive and drive blank
modules in bay-number sequence and organize
them on your work surface in bay-number
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
CAUTION: 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.
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.
Reinstalling 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).
NOTE: For clarity, only relevant details are
shown in this illustration. Port and LED
information is not included.
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
CAUTION: Because drives are heavy, HP
recommends moving the chassis with no drives
installed. If this is not possible, two or more people
are required to lift the chassis.
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: As a best practice, 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 return 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. Host
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
whether the failed component must be returned. Follow the
provided instructions.
