Complete host interface card upgrade

You complete the process of upgrading a host interface card by checking the controller LEDs and seven-segment display and confirming that the controller's status is Optimal.

Before you begin

  1. Turn on the two power switches at the back of the controller shelf.
    • Do not turn off the power switches during the power-on process, which typically takes 90 seconds or less to complete.
    • The fans in each shelf are very loud when they first start up. The loud noise during start-up is normal.
  2. As the controller boots, check the controller LEDs and seven-segment display.
    • The seven-segment display shows the repeating sequence OS, Sd, blank to indicate that the controller is performing Start-of-day (SOD) processing. After a controller has successfully booted up, its seven-segment display should show the tray ID.
    • The amber Attention LED on the controller turns on and then turns off, unless there is an error.
    • The green Host Link LEDs remain off until you connect the host cables.
    Note: The figure shows an example controller canister. Your controller might have a different number and a different type of host ports.

  3. From ThinkSystem System Manager, confirm that the controller's status is Optimal.
    If the status is not Optimal or if any of the Attention LEDs are on, confirm that all cables are correctly seated, and check that the HIC and the controller canister are installed correctly. If necessary, remove and reinstall the controller canister and the HIC.
    Note: If you cannot resolve the problem, contact technical support.
  4. If the new HIC ports require SFP+ transceivers, install these SFPs.
  5. Connect the cables from the controller's host ports to the data hosts.

The process of upgrading a host interface card in your storage array is complete. You can resume normal operations.
