The two USB ports available on the front panel of the server 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:
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.
When the host reaches the ok prompt, remove any external hubs and attach the USB device directly to a USB 3.0 connector on the rear of the server, or use another standard compliant USB device. Then retry the operation.
If the host does not display the ok prompt, remove any external hubs and attach the USB device directly to a USB 3.0 connector on the rear of the server, or use another standard USB compliant device. Then power cycle the host using one of these methods:
Using the Oracle ILOM CLI:
-> reset /System
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.
