I need to use an external USB drive on our Novell servers. I have named, formatted NSS, and mounted said hardware. It works as expected. I need this device to be portable. What is the GRACEFUL way to turn off the USB controller, or drivers? I prefer to avoid the "External (USB) deactivatedby driver due to device failure" error when just powering off the external drive. Using remote manager, I see how to deactivate the USB OHCI Controller. I am looking for a console command to use in conjunction with dismount volume.

Thank You
