Upgrading DPU controllers

Resolution

  1. Connect to the controller, select Edit/ Host Computer/Network Configuration
  2. Penetrate the Link Summary, Penetrate the Controller, penetrate the DPUs
  3. At this point the rev level will be different, do not modify it to put the correct rev level.
  4. Instead leave it blank and the software will fill it in automatically.
