redhat6操作系统采用multipath多路径软件时如何绑定裸设备

下面介绍一下在redhat6操作系统上采用multipath多路径软件时，如果要安装Oracle 11g RAC，如何绑定裸设备。

vi /etc/udev/rules.d/60-raw.rules

# Device mapper raw rules

KERNEL!="dm-[0-9]*", GOTO="skip_dm"

ACTION!="change", GOTO="skip_dm"

PROGRAM!="/sbin/dmsetup ls --exec /bin/basename -j %M -m %m", GOTO="skip_dm"

RESULT=="mpath0", RUN+="/bin/raw /dev/raw/raw1 /dev/mapper/mpath0"

RESULT=="mpath1", RUN+="/bin/raw /dev/raw/raw2 /dev/mapper/mpath1"

RESULT=="mpath2", RUN+="/bin/raw /dev/raw/raw3 /dev/mapper/mpath2"

RESULT=="mpath3", RUN+="/bin/raw /dev/raw/raw4 /dev/mapper/mpath3"

RESULT=="mpath4", RUN+="/bin/raw /dev/raw/raw5 /dev/mapper/mpath4"

RESULT=="mpath5", RUN+="/bin/raw /dev/raw/raw6 /dev/mapper/mpath5"

RESULT=="mpath6", RUN+="/bin/raw /dev/raw/raw7 /dev/mapper/mpath6"

RESULT=="mpath7", RUN+="/bin/raw /dev/raw/raw8 /dev/mapper/mpath7"

RESULT=="mpath8", RUN+="/bin/raw /dev/raw/raw9 /dev/mapper/mpath8"

RESULT=="mpath9", RUN+="/bin/raw /dev/raw/raw10 /dev/mapper/mpath9"

RESULT=="mpath10", RUN+="/bin/raw /dev/raw/raw11 /dev/mapper/mpath10"

LABEL="skip_dm"

KERNEL=="raw1", ACTION=="add", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="raw2", ACTION=="add", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="raw3", ACTION=="add", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="raw4", ACTION=="add", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="raw5", ACTION=="add", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="raw6", ACTION=="add", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="raw7", ACTION=="add", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="raw8", ACTION=="add", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="raw9", ACTION=="add", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="raw10", ACTION=="add", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="raw11", ACTION=="add", OWNER="grid", GROUP="asmadmin", MODE="0660"

然后执行如下命令：

#/sbin/udevadm control --reload-rules

#start_udev
