It's ENOSYS, not EPERM.  I'm running this script as root.

Specifically, the code is here in the Linux kernel (2.4.17), in
drivers/scsi/scsi.c:

    for (scd = HBA_ptr->host_queue; scd; scd = scd->next) {
            if ((scd->channel == channel
                  && scd->id == id
                  && scd->lun == lun)) {
                    break;
            }
    }

    err = -ENOSYS;
    if (scd)
            goto out;       /* We do not yet support unplugging */
