I tried: echo "scsi remove-scingle-device 1 0 13 0" > /proc/scsi/scsi <device removed from /proc/scsi/scsi list> echo "scsi add-scingle-device 1 0 13 0" > /proc/scsi/scsi <device does not show up in /proc/scsi/scsi list>
I also tried your method, which just gives invalid argument (using /proc/scsi/scsi, since /proc/scsi is a directory)
According to scsi_proc.c: /* * Usage: echo "scsi add-single-device 0 1 2 3" >/proc/scsi/scsi * with "0 1 2 3" replaced by your "Host Channel Id Lun". */
/* * Usage: echo "scsi remove-single-device 0 1 2 3" >/proc/scsi/scsi * with "0 1 2 3" replaced by your "Host Channel Id Lun". */
Either way, nothing.
Er, on second though, I actually unplugged the power from the scsi device and replugged it and it shows up now. Oh well.. Thanks anyway =)
