1.拿到編號(hào)

[root@Node01 ~]# udevadm info -q path -n /dev/sda

/devices/pci0000:00/0000:00:15.0/0000:03:00.0/host0/target0:0:0/0:0:0:0/block/sda

[root@Node01 ~]# udevadm info -q path -n /dev/sdb

/devices/pci0000:00/0000:00:15.0/0000:03:00.0/host0/target0:0:1/0:0:1:0/block/sdb

[root@Node01 ~]# udevadm info -q path -n /dev/sdc

/devices/pci0000:00/0000:00:15.0/0000:03:00.0/host0/target0:0:2/0:0:2:0/block/sdc

[root@Node01 ~]# udevadm info -q path -n /dev/sdd

/devices/pci0000:00/0000:00:15.0/0000:03:00.0/host0/target0:0:3/0:0:3:0/block/sdd

2.編輯

[root@Node01 ~]# vi /etc/udev/rules.d/80-mydisk.rules

DEVPATH=="/devices/pci0000:00/0000:00:15.0/0000:03:00.0/host0/target0:0:0/0:0:0:0/block/sda, NAME="sd*", MODE="0660"

DEVPATH=="/devices/pci0000:00/0000:00:15.0/0000:03:00.0/host0/target0:0:1/0:0:1:0/block/sdb, NAME="sd*", MODE="0660"

DEVPATH=="/devices/pci0000:00/0000:00:15.0/0000:03:00.0/host0/target0:0:2/0:0:2:0/block/sdc, NAME="sd*", MODE="0660"

DEVPATH=="/devices/pci0000:00/0000:00:15.0/0000:03:00.0/host0/target0:0:3/0:0:3:0/block/sdd, NAME="sd*", MODE="0660"
