安装emc多路径必须把系统内核多路径删除
这里针对centos7系统为例：(Disabling dm-multipath on a RHEL 7 or OL 7 host )
1) Blacklist all devices in /etc/multipath.conf
默认情况下，multipath会把所有设备都加入到黑名单（devnode "*"），也就是禁止使用。所以，我们首先需要取消该设置，把配置文件修改为类似下面的内容：
# cat /etc/multipath.conf
blacklist {
devnode "*"
}2) Restart multipathd service for the multipath config file to get into effect:
# systemctl restart multipathd3）Stop dm-multipath service and ensure dm-multipath does not start automatically on boot.
# systemctl stop multipathd关闭开机自启动
# systemctl disable multipathd
Removed symlink /etc/systemd/system/sysinit.target.wants/multipathd.service.4)重新创建ramdisk映像，以便从ramdisk映像中排除dm-multipath。
Recreate ramdisk image so that dm-multipath is excluded from ramdisk image.
# dracut /boot/initramfs-wo-DM-$(uname -r).img $(uname -r)5）更新grub.cfg文件中的新条目，并将其设置为默认值。（Update the new entry in the grub.cfg file and make it as default.）
系统使用新的ramdisk映像自动引导。(The system boots with the new ramdisk image automatically.)
# grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub configuration file ...

done# grub2-set-default 'PowerPath - Red Hat Enterprise Linux Server'6）使用新的ramdisk映像重新启动主机，并确保dm-multipath没有任何配置的设备。
(Restart the host with the new ramdisk image and ensure that the dm-multipath does not have any configured devices.)
