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 Systems Safety Notices. These guidelines help you safely work

with the Storwize V7000.
