Remove failed controller

You remove a controller canister to replace the failed canister with a new one. Perform this task only if your storage array has two controllers.

  1. Step 1: Remove controller canister
    Remove the failed controller canister so you can replace it with a new one.
  2. Step 2: Remove battery
    Remove the battery so you can install the new controller.
  3. Remove host interface card
    If the controller canister includes a host interface card (HIC), you must remove the HIC from the original controller canister, so you can reuse it in the new controller canister.
