Some USB 3.0 Devices Cause Timeouts and Might Hang the Host (16019551 and 15985683)

The two USB ports available on the front dongle of the server module are USB 2.0 compliant. If you use some USB 3.0 devices (especially those behind external USB hubs) to install the OS or to boot, the action might get stuck and display these messages:

WARNING: 
/pci@340/pci@1/pci@0/pci@2/usb@0/hub@5/hub@3/storage@1/disk@0,0
(sd12): SCSI transport failed: reason 'timeout': giving up

In some extreme cases, this situation might cause the host to experience a hard hang.

Workaround:

  1. Send a break to the host and connect to the host console using one of these methods:

    • Using the Oracle ILOM CLI:

      -> cd /HOST
      -> set send_break_action=break
      -> start /HOST/console
      
    • Using the Oracle ILOM web interface:

      a. Select Host Management > Power Control.

      b. Select Reset for Select Action and click Save.

      c. Click OK on the pop-up menu.

  2. When the host reaches the ok prompt, remove any external hubs and attach the USB device directly to the front dongle or use another standard compliant USB device and retry the operation.

  3. If the host does not display the ok prompt, remove any external hubs and attach the USB device directly to the front dongle port or use another standard USB-compliant device, then power cycle the host using one of these methods:

    • Using the Oracle ILOM CLI:

      -> reset /SYS
      
    • Using the Oracle ILOM web interface:

      a. Select Host Management > Power Control.

      b. Select Reset for Select Action and click Save.

      c. Click OK on the pop-up menu.
