Hello Elaine,
If the modules doesn't loads, or the systems doesn't detects any previously added peripheral, you may try to : 1# Code:
/etc/init.d/kudzu start 3# unplug the card/equipment and re-plug it in another bus 4# power on your server Then, could you tell me if the kudzu auto-configuration assistant loads up (don't forget to press 'i' when booting up) ? g33ky BTW, which version of RHEL (or Fedora) are you running ? Thx |

thx reply , but what I want is just not reboot the system again , I would like to force to rescan the device . Thx |
Ok,
Can you tell me what kind of hardware do you want to be found by the system ? Any HBA, ethernet card, SCSI equipment or other ? It would be perfect if could give me the kind, manufacturer, and product type of the card. So that I could give you the precise command to reload the driver stack. But if you feel a little ninja, this is the path to follow : For example, to force a rescan for a QLogic HBA : Code:
# echo "scsi-qlascan" > /proc/scsi/<driver-name>/<adapter-id> - <driver-name> = qla2100, qla2200, qla2300 (2.4 kernel drivers) or qla2xxx (2.6 kernel drivers) - <adapter-id> = the instance number of the HBA Then, you have to force the 'mid-layer' to rebuild the node entry table : Code:
# echo "scsi add-single-device 0 1 2 3" >/proc/scsi/scsi - "0 1 2 3" = your "Host Channel ID LUN" That's it. Don't forget to give me the details if you want me to help you a little bit more. Thanx, g33ky |
How could I force my computer to scan wifi dongles at boot up? I have to unplug and plug the dongle back in to get detected at every boot up... :(
