You can replace an expansion enclosure.
Note: Ensure that you know the type of enclosure chassis that
you are replacing. The procedures for replacing an expansion enclosure
chassis are different from those procedures for replacing a control
enclosure chassis. To replace a control enclosure chassis, see
Replacing a control enclosure chassis.
DANGER
When working on or around the system, observe
the following precautions:
Electrical voltage and current from
power, telephone, and communication cables are hazardous. To avoid
a shock hazard:
- If Lenovo supplied a power cord(s), connect power to this unit
only with the Lenovo provided power cord. Do not use the Lenovo provided
power cord for any other product.
- Do not open or service any power supply assembly.
- Do not connect or disconnect any cables or perform installation,
maintenance, or reconfiguration of this product during an electrical
storm.
- The product might be equipped with multiple power cords. To remove
all hazardous voltages, disconnect all power cords.
- Connect all power cords to a properly wired and grounded electrical
outlet. Ensure that the outlet supplies proper voltage and phase rotation
according to the system rating plate.
- Connect any equipment that will be attached to this product to
properly wired outlets.
- When possible, use one hand only to connect or disconnect signal
cables.
- Never turn on any equipment when there is evidence of fire, water,
or structural damage.
- Disconnect the attached power cords, telecommunications systems,
networks, and modems before you open the device covers, unless instructed
otherwise in the installation and configuration procedures.
- Connect and disconnect cables as described in the following procedures
when installing, moving, or opening covers on this product or attached
devices.
To disconnect:
- Turn off everything (unless instructed otherwise).
- Remove the power cords from the outlets.
- Remove the signal cables from the connectors.
- Remove all cables from the devices.
To connect:
- Turn off everything (unless instructed otherwise).
- Attach all cables to the devices.
- Attach the signal cables to the connectors.
- Attach the power cords to the outlets.
- Turn on the devices.
- Sharp edges, corners and joints might be present in and around
the system. Use care when handling equipment to avoid cuts, scrapes
and pinching.
Attention: If your system is powered on and performing I/O operations,
go to the
management GUI and follow the fix procedures. Performing the replacement actions
without the assistance of the fix procedures can result in loss of
data or access to data.
Even though many parts are hot-swappable,
these procedures are intended to be used only when your system is
not up and running and performing I/O operations. Unless your system
is offline, go to the management GUI and follow the fix procedures.
Be careful when
you are replacing the hardware components that are located in the
back of the system that you do not inadvertently disturb or remove
any cables that you are not instructed to remove.
Ensure that you are aware of the procedures for handling static-sensitive
devices before you remove the enclosure.
Note: If your system is online, replacing an expansion enclosure
can cause one or more of your volumes to go offline or your quorum
disks to be inaccessible. Before you proceed with these procedures,
verify which volumes might go offline. From the management GUI, go to . Select the enclosure that you want
to replace. Then, select Show Dependent Volumes in the Actions menu.
To replace an expansion enclosure chassis, perform the
following steps:
- Shut down the I/O activity to the enclosure,
which includes host access, FlashCopy, Metro Mirror, and Global Mirror
access.
- Turn off the power to the enclosure by disconnecting the
power cable.
- Record which data cable is plugged into each specific port.
The cables must be inserted back into the same ports after the replacement
is complete; otherwise, the system cannot function properly.
- Disconnect the data cables for each canister.
- Remove the power supply units from the enclosure.
- Remove the canisters from the enclosure.
- Remove all the drives and blank drive assemblies from the
enclosure. Record the location for each drive. They must be inserted
back into the same location in the new enclosure.
- Remove both enclosure end caps from the enclosure.
Keep the left end cap because it is used again.
- Remove the clamping screws that attached the enclosure
to the rack cabinet.
- Remove the enclosure chassis from the front of the rack
cabinet and take the chassis to a work area.
- Install the new enclosure chassis in the rack cabinet.
- Remove the end caps from the new enclosure and install
the clamping screws that attach the enclosure to the rack cabinet.
- Replace the end caps. Use the new right end cap and use
the left end cap that you removed in step 8.
Using the left end cap that you removed preserves the model
and serial number identification.
- Reinstall drives in the new enclosure. You must insert
the drives back into the same location from which they were removed
on the old enclosure.
- Reinstall the canisters (and drives) in the
enclosure.
- Install the power supply units.
- Use the information that you recorded previously to reattach
the data cables to each canister.
Note: The cables must be inserted back into the same ports from
which they were removed on the old enclosure; otherwise, the system
cannot function properly.
- Attach the power cords and the cable retention brackets
to the power supply units.
- Write the old enclosure machine type and model (MTM) and
serial number on the repair identification (RID) tag that is supplied.
Attach the tag to the left flange at the back of the enclosure.
The system records an error that indicates that an enclosure
FRU replacement was detected. Go to the management GUI to use the fix procedure to change the machine type and model and
serial number in the expansion enclosure.
If we remove the "5. Turn on the devices" I believe all this safety applies.We can roll out a version of it into the remove/replace topics that need it. LA
