On 2.6, look in /sys/bus/pci/slots for the different pci slots (after you have loaded the proper pci hotplug driver for your hardware.) To add or remove a card, simply echo 0 or 1 in the power file in the slot that you wish to turn on or off. I recommend using the pcihpview program if you don't like using echo, as it is a gui driven program to do the same thing. The FC-HBA portion is the same if it's hotplugged or not, no difference there. > and PnP of SCSI disk". It should just be added, if the whole FC-HBA comes up. If you mean adding another one later on, after the controller card has scanned the bus, I don't know, ask the scsi people. Hope this helps. greg k-h
