October 19, 20196 yr I have an egpu setup with my unraid server. Had a spare 980ti that I wanted to use for infrequent rendering task in a VM. But I don't want to leave the gpu running idle all the time as it will probably still suck up 20-30W. I only want to power on the egpu when I am about to run some rendering tasks. I rigged up an egpu setup where it has its own standalone power supply and connects to a pcie slot on the unraid server. However when I power on the egpu, it can't be initialized by unraid until i reboot the server. Just a minor inconvenience. Is there a console command where I can reinitialize specific IOMMU groups or pci devices, so I don't need to reboot. I wouldn't want to reinitialize all devices... Thanks. Any help would be much appreciated.
