Preparing for the replacement
If the controller enclosure or drive enclosure chassis is
operational, do the following:
Stop all I/O to the storage system that includes the
Shutdown all array controllers in the system.
To shutdown a controller using the SMU, select the

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.
Because drives are heavy, HP recommends
removing drives prior to moving the chassis. If
this is not possible, two or more people are
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
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
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 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
