Upgrade host interface card

You upgrade a host interface card (HIC) to increase the number of host ports or to change host protocols. When you upgrade the HICs, you must power off the storage array, remove the existing HIC from each controller, install a new HIC, and reapply power.

  1. Prepare to upgrade host interface cards
    You prepare to upgrade host interface cards (HICs) by backing up the storage array's configuration database, collecting support data, and stopping host I/O operations. Then, you can power down the controller shelf.
  2. Upgrade host interface card
    You upgrade a host interface card (HIC) to increase the number of host ports or to change host protocols. If you are upgrading HICs in a two-controller configuration, repeat all steps to remove the other controller canister, remove the HIC, install the new HIC, and replace the second controller canister.
  3. 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.
