Replacing a Lenovo Storage V7000 Gen1 expansion enclosure chassis

You can replace an expansion enclosure chassis.

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:
1. Turn off everything (unless instructed otherwise).
2. Remove the power cords from the outlets.
3. Remove the signal cables from the connectors.
4. Remove all cables from the devices.
To connect:
1. Turn off everything (unless instructed otherwise).
2. Attach all cables to the devices.
3. Attach the signal cables to the connectors.
4. Attach the power cords to the outlets.
5. 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 of the 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 Home > Manage Devices. 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 using the switches on the power supply units.
Record which data cables are plugged into the specific ports. The cables must be inserted back into the same ports after the replacement is complete; otherwise, the system cannot function properly.
Disconnect the cable retention brackets and the power cords from the power supply units.
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 9.
Using the left end cap that you removed preserves the model and serial number identification.
Reinstall the drives in the new enclosure. The drives must be inserted back into the same location from which they were removed on the old enclosure.
Reinstall the canisters in the enclosure.
Install the power supply units.
Reattach the data cables to each canister by using the information that you recorded previously.
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.
Turn on the power to the enclosure by using the switches on the power supply units.
The system records an error that indicates that an enclosure FRU replacement was detected.
Important: Step 22 writes the enclosure identity into the replacement midplane. The replacement midplane cannot be used as a replacement part for a different enclosure after step 22 is completed.
Go to the management GUI to use the fix procedure to change the machine type and model and serial number in the expansion enclosure.
