Chapter 2. Operating the controller unit 25
Preparing to move the controller unit
Remove each component CRU before moving the controller unit to a new location or
before removing the chassis from its cabinet. This helps safeguard the equipment and
ensures a smoother transition to the new environment.
If you are moving the controller unit a short distance (within the same building), and you
have sufficient assistance (one or more additional helpers) or equipment (such as a fork
lift), you might be able to move the controller unit without removing each component
CRU. If you do not have sufficient assistance or equipment, use the procedure in
"Removing and installing the components" to safely move the equipment to its new
location.
If you are moving the controller unit a significant distance (for example, to another
building or city), be sure to pack it in its original shipping container.
For more information about assembling or disassembling the controller unit, refer to the
IBM Netfinity FAStT500 RAID Controller Enclosure Unit Installation Guide.
Removing and installing the components
Use the following procedure to remove all component CRUs before moving or relocating
the controller unit. Replace the CRUs after you complete the procedure.
1 Prepare the controller unit for shutdown, as follows:
a Stop all I/O activity to the controller unit and attached drive enclosures.
b Logically disconnect the controller and drive enclosures from the hosts.
c Make sure that the fast write cache indicator light on the front bezel is off (not
blinking).
d Make sure that all applicable drive active indicator lights on each drive enclosure
front panel are off (not blinking).
Note: If a parity check is in progress, it can take a long time for the drive indicator
lights to stop blinking.
2 Remove the controller unit bezel, as shown in Figure 6 on page 11 .
3 Make sure that all amber fault indicator lights on the controller unit are off. If any fault
indicator lights are on, correct the problem before turning off the power. For more
information, see
"Checking the indicator lights" on page 15 .
