Adding two host interface adapters to an operational system

This topic describes how to install a pair of host interface adapters in an operational system.

Follow the following steps to install a pair of host interface adapters while the system continues to perform I/O operations.

1. In the management GUI, check the Recommended Actions event log view, resolve any issues that exist before continuing.
2. To safely remove a node canister without disrupting I/O, refer to Procedure: Removing a node canister.
3. Remove the lid from the canister.
   For instructions, refer to Procedure: Removing and replacing lid of a node canister.
4. If the host interface adapter has SFP transceivers, remove them.
   To remove a transceiver, swing the release handle open and use it to pull the transceiver out of the host interface adapter port (Figure 1).

5. Loosen the retaining thumbscrew 1 , as shown in Figure 2.

   • 1 Retaining thumbscrew
   • 2 Filler handle
   • 3Host interface adapter
   • 4 Catch slot
6. From inside the canister, grasp the filler handle 2 and slide the filler plate toward the thumbscrew to disengage the plate from the catch slot 4.
7. Remove the filler plate.
8. Insert the host interface adapter3 into the canister as shown in Figure 2
9. Align the mounting bracket of the host interface adapter with the inside of the host interface adapter aperture at the thumbscrew end of the canister, ensuring that the tab at the end of the faceplate is aligned with the catch slot 4.
10. Align the connecting edge of the host interface adapter with the slot in the host interface adapter connector inside the canister.
11. Apply pressure to the opposite edge of the host interface adapter to push the adapter into the connector.
12. Check that the host interface adapter is installed squarely in its slot and tighten the retaining thumbscrew 1.
13. Reinstall the lid on the canister.
    Refer to Procedure: Removing and replacing lid of a node canister.
14. If you removed SFP transceivers in step 4, reinstall them.
    To install a transceiver, push it fully into the port and close the release handle.
15. If you purchased an additional 2-transceiver option, install the extra SFP transceivers in the remaining ports.
    You can install one or two extra transceivers in the canister. You must install the same number in both canisters in the enclosure.
16. Reinstall the canister in the enclosure, replace any cables that were removed, and install the cables that will connect the host interface adapter to host systems.
    Do not attempt to connect the cables to any host systems until instructed to do so.
    The canister restarts. Because the hardware configuration has changed, a node error (841) and associated alert (1199) are recorded in the system event log.
17. Use the Recommended Action in the management GUI monitoring page to check and accept the hardware changes.
    The node canister restarts as part of this process. When the system restarts, an alert 1470 indicates that the node canister hardware does not match. You can ignore this alert.
18. Repeat steps 2 to 16 for the second canister.
    Before powering off the second canister, verify that host systems have rediscovered the first canister so they can fail over it when the second canister is removed.
19. Use the Recommended Action in the management GUI monitoring page to check and accept the hardware changes reported in the 1199 error.
    The node canister restarts. The mismatched hardware error 1470 is automatically cleared.
