Chapter 8. Removing and replacing parts

You can remove and replace field-replaceable units (FRUs) from the control

enclosure or the expansion enclosure.

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 these procedures 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.

Each replaceable unit has its own removal procedure. Sometimes you can find that

a step within a procedure might refer you to a different remove and replace

procedure. You might want to complete the new procedure before you continue

with the first procedure that you started.

Remove or replace parts only when you are directed to do so.

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.

Before you remove and replace parts, you must be aware of all safety issues.

First, read the safety precautions in the IBM Storwize V7000 Safety Notices. These

guidelines help you safely work with the Storwize V7000.
