1,在该路劲下创建50-udev.rules文件，将要创建成ASM设备的裸设备添加进去，并指定OWNER

两个节点进行创建

[root@oraclea rules.d]# pwd
/etc/udev/rules.d
[root@oraclea rules.d]# cat 50-udev.rules
SUBSYSTEM=="block", KERNEL=="sdb", GROUP="asmadmin", OWNER="grid", MODE="0660"
SUBSYSTEM=="block", KERNEL=="sdc", GROUP="asmadmin", OWNER="grid", MODE="0660"
SUBSYSTEM=="block", KERNEL=="sdd", GROUP="asmadmin", OWNER="grid", MODE="0660"
SUBSYSTEM=="block", KERNEL=="sde", GROUP="asmadmin", OWNER="grid", MODE="0660"
SUBSYSTEM=="block", KERNEL=="sdf", GROUP="asmadmin", OWNER="grid", MODE="0660"
SUBSYSTEM=="block", KERNEL=="sdg", GROUP="asmadmin", OWNER="grid", MODE="0660"
SUBSYSTEM=="block", KERNEL=="sdh", GROUP="asmadmin", OWNER="grid", MODE="0660"

创建后启动UDEV服务

[root@oraclea rules.d]#/sbin/start_udev

一般情况下都会报udev[31488]，提示匹配不到这个文件的标签

/lib/udev/rules.d/90-pulseaudio.rules

所以需要对这个文件进行修改

[root@oraclea rules.d]# cat /lib/udev/rules.d/90-pulseaudio.rules

LABEL="pulseaudio_end"

将红色部分注释掉就可以正常启动UDEV了
