Attention: If you install a host port adapter in a controller and the storage subsystem contains two controllers, you must ensure that an identical host port adapter is installed in the other controller.
Before you begin, ensure that you wear an anti-static wrist strap.
To install a host port adapter, complete the following steps.
Attention: When you add a host port adapter to an existing configuration the subsystem must be powered off, and you must schedule maintenance time to perform this task offline. To prevent data loss, you must shut down the storage subsystem before you remove the controller from the chassis. For the correct shutdown sequence, see “Turning off the storage subsystem” on page 95. However, you do not have to power off the subsystem when replacing a failed host port adapter in a dual controller subsystem.
1. Read the safety information that begins on page “Safety” on page ix and “Best practices guidelines” on page 8.
2. If you are replacing a failed host port adapter, skip to the next step.
Otherwise, turn off the storage subsystem (see “Turning off the storage subsystem” on page 95).
3. Label all of the cables that are connected to the controller, then disconnect those cables.
4. Remove the controller from the chassis.

a. Open the two release levers as shown in the illustration. The controller moves out of the bay approximately 0.6 cm (0.25 inch).
b. Pull the controller out of the bay.
DANGER
Electrical voltage and current from power cables are hazardous. To avoid a shock hazard, always place electrical equipment on dry, static-free level surfaces. Never turn on any electrical equipment when there is evidence of fire, water, or structural damage.
c. Place the controller on a dry, static-free level surface.
5. Remove the cover (see “Removing and installing a cover” on page 107).
6. If no host port adapter is installed, skip to the next step. Otherwise, release the four captive thumbscrews that hold the host port adapter to the controller board. Then, remove the host port adapter by lift it slightly upward to release it from the board connector, and pull it away from the front of the controller module.
7. If you are replacing a failed host port adapter, skip to the next step.
Otherwise, remove the two screws from the cover plate. Flip the top edge of the cover plate outward to release the alignment tab and remove the cover plate from the controller.

8. Touch the static-protective package that contains the host port adapter to any unpainted metal surface on the storage subsystem; then, remove the adapter from the package.
9. If you are replacing a failed host port adapter, skip to the next step.
Otherwise, install the host port cover that comes with the optional host port adapter.
a. Place the alignment tab/edge inside the host port cutout.
b. Secure the host port cover with two screws.
10. Align the host port adapter as shown in the following illustration. The host port will protrude slightly from the host port cover. Because the host port cover cutout is a tight fit, you must apply slight pressure to get the port connectors through the cutout.

11. Ensure that the host port adapter connector and the controller board connector are aligned. Do not force fit, but use slight pressure to press the card in the connector. Then, tighten the four captive fasteners.
12. Install the cover (see “Removing and installing a cover” on page 107).
13. Insert the controller into the chassis.
a. Ensure that the release levers on the controller are in the open position.
b. Slide the controller into the bay until it stops.
c. Push the release levers to the closed position.
14. Reconnect the cables that you disconnected in step 3 on page 116.
15. If you are replacing a failed host port adapter operation in a dual-controller subsystem, skip to the next step. Otherwise, if a second controller exists, repeat the preceding steps for the second controller beginning with 3 on page 116.
16. Turn on the storage subsystem (see “Turning on the storage subsystem” on page 82).
17. Wait up to 5 minutes for the Storage Manager software to recognize the controller.
18. Check the LEDs on the controller to ensure that the controller is fully operational.
19. Use the Subsystem Management window to check the status of all components in the storage subsystem.
v If the controller is online and the Subsystem Management window indicates normal operation, go to step 22 on page 121.
v If the controller is online and the Subsystem Management window indicates a problem status, go to “Troubleshooting the storage subsystem” on page 87.
v If the controller is offline, continue with step 20.
20. If the newly inserted controller is in an offline state, see the Storage Manager online help for instructions on bringing the controller online. If necessary,

open the Subsystem Management window and place the controller online;
select the offline controller and click Advanced → Recovery → Place controller online.
21. Verify the state of the LEDs on the newly inserted controller. See “Controller LEDs” on page 90. You can also use the Subsystem Management window to identify any new faults. Do any storage subsystems have a fault (Needs Attention) status?
v Yes:Click Recovery Guru in the Subsystem Management window toolbar, and complete the recovery procedure. If the problem remains, contact your IBM technical-support representative.
v No:Go to step 22.
22. Use the Storage Manager software to print a new storage subsystem profile.
23. Check the WWIDs or the MAC addresses of the host ports after replacing the controller and/or the host port interface adapter. If you need to change any WWID or MAC address, update the servers or switches in the configuration.
