问个写UDEV的匹配

whoiswhoz

查看硬件
udevinfo -a -p /sys/block/sda|less

looking at class device '/sys/block/sda':
    SYSFS{dev}="8:0"
    SYSFS{range}="16"
    SYSFS{removable}="0"
    SYSFS{size}="3907029168"
    SYSFS{stat}="     125      386     3923      124        1       33      256        2        0      126      126"

follow the class device's "device"
  looking at the device chain at '/sys/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0':
    BUS="scsi"
    ID="0:0:0:0"
    SYSFS{detach_state}="0"
    SYSFS{device_blocked}="0"
    SYSFS{model}="ST32000644NS    "
    SYSFS{queue_depth}="1"
    SYSFS{rev}="SN11"

我想根据BUS和ID来匹配硬件，并把这个硬件归为/dev/sdz
我在/etc/udev/rules.d/51-by-id.rules中添加
BUS=="scsi", ID=="0:0:0:0", SYMLINK="sdz"



但是运行报错
udevtest /sys/block/sda
version 039
looking at '/block/sda'
parse error /etc/udev/rules.d/51-by-id.rules, line 10:0, rule skipped
creating device node '/dev/sda', major = '8', minor = '0', mode = '060660', uid = '0', gid = '6'

第十行就是我写的


求怎么修改，系统RHEL4.8
