Warranties for Hewlett Packard Enterprise
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. Hewlett Packard Enterprise

Moving side brackets to the replacement
chassis.
Moving power and cooling, controller, I/O, and
air management modules to the replacement
chassis.
Installing the replacement chassis in the rack.
Installing drive or drive blank modules in the
replacement chassis.
Completing the process and verifying proper
operation.
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.
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.
2.
3.
Do the following before beginning these procedures:
•
Verify that there is a recent backup of the
system.
Send any errors, suggestions, or comments to Documentation Feedback
(docsfeedback@hpe.com).
•
Record system settings.
•
Label all cables.
•
Prepare a large, stable work surface.
Turn off power and cooling module switches (if
present).
Make sure the cables are clearly labelled and
then disconnect the cables, including the power
cords, from the modules.

3.
•
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.
Procedural overview
*590358-009*
These procedures require that all drives
be removed from the failed chassis and
then installed in the replacement chassis.
•
Because drives are heavy, Hewlett
Packard Enterprise 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.
Press and slide the release latch button to
release the latch handle (1).
Rotate out the latch handle to disengage the
module from the internal connector (2).
Pull the module straight out of the chassis (3).

IMPORTANT: Use caution when handling
Fibre Channel cables:
Schedule a maintenance window that will
include time for shutdown, sixty minutes of
replacement work, and restart.

Removing drive and drive blank modules
from the failed chassis
3.
4.
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.
Page 1
Remove the ear bezels by grasping each bezel
firmly and pulling until the bezel separates from
the ball nuts on the chassis ear.
Remove retaining screws securing the front and
rear of the chassis to the rack and rails.
Remove the chassis from the rack.
Place the failed chassis on the work surface
near the replacement chassis.
2.
Moving side brackets to the replacement
chassis
1.
2.
Install power and cooling modules in the
replacement chassis.
3.
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.
Remove the side bracket from each side of the
failed chassis.
Attach the side bracket to each side of the
replacement chassis.
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
1.
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.
Moving power and cooling modules to
the replacement chassis
1.
2.
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).
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.
Completing the process
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.
With the latch in the open position, slide the
module into the drive slot as far as it will go (1).
Rotate the latch closed until it clicks (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.
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.
Reconnect power cords to the devices.
Turn on power and cooling module switches (if
present).
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
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→Rescan.
IMPORTANT: Reinstall each drive or drive
blank module in the same bay number from
which it was removed.
