6. Determine whether the replacement controller will serve as controller A or
controller B. (Controller A is inserted in the left controller bay; controller B is
inserted in the right controller bay.) Apply the controller labels for host
channels, drive channels, and numeric display to the replacement controller.
The controller labels and instructions are included with the replacement
controller. Make sure that the labels are aligned properly and do not cover
any ports or LEDs.
Attention: Handle and install fibre-optic cables properly to avoid degraded
performance or loss of communications with devices. For specific handling
guidelines, see the section on handling fibre-optic cables in the IBM System
Storage DS4000 EXP420 Storage Expansion Enclosure Installation, User’s and
Maintenance Guide (GC27-2050).
7.
Disconnect all attached interface cables from the failed controller, including
the SFP modules. Ensure that you label each cable so that you can reconnect
them correctly to the new controller.
Use the following procedure to remove the SFPs from the RAID controller that
has failed:
a. Remove the LC-LC fibre-channel cable from the SFP module.
b. Unlock the SFP module latch:
v
For SFP modules that contain plastic tabs, unlock the SFP module latch
by pulling the plastic tab outward 10°, as shown in Figure 34.
v
For SFP modules that contain wire tabs, unlock the SFP module latch by
pulling the wire latch outward 90°, as shown in Figure 35.
c. With the SFP latch in the unlocked position, extract the SFP module.
v For SFP modules that contain plastic tabs, slide the SFP module out of
the port.
