    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 =)
