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.

Before you begin
Observe the following:
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
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.

Preparing for the replacement
If the controller enclosure or drive enclosure chassis
is operational, do the following to shutdown the
Stop all I/O to the storage system that includes
the failed chassis.
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.
Turn off power and cooling module switches (if
Make sure the cables are clearly labelled and then
disconnect the cables, including the power cords,
from the modules.
Use caution when handling Fibre
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
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.
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).
Removing the failed chassis from the rack
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.
