redhat7.0多路径安装rpm包后，multipah -ll没反应

sunxuekunmm

大家帮忙看一下，我redhat7.0配置多路径，怎么用multipath -ll 没有反应呢？是不是缺少什么报呀，谢谢！
下面是安装的rpm包：
[root@localhost ~]# rpm -qa | grep device
device-mapper-multipath-0.4.9-66.el7.x86_64
device-mapper-event-1.02.84-14.el7.x86_64

你是否配置了多路径发现设备？

如果没有配置设备,只安装了软件，执行这个命令是没有反馈的

sunxuekunmm

发现设备是那个 呀？请指教，我再6里面也没有安装发现设备呀，直接打上三个包配置一下/etc/multiapth.conf就可已了

mpathconf --enable 生成配置文件
然后启动multipath

好像还是不行，
[root@rh7rac1 ~]# mpathconf --enable
[root@rh7rac1 ~]# systemctl stop multipathd.service
[root@rh7rac1 ~]# systemctl start multipathd.service
[root@rh7rac1 ~]# multipath -ll
[root@rh7rac1 ~]# ll /dev/mapper/

已经搞定，本来准备放弃在redhat7上安装了，今早又坚持了一下，终于搞定，感谢@63661819 和@jixuuse两位同学的帮助，最后在下面这篇文章中找到答案，再次感谢！感觉之前的问题还是multipath.conf文件没有配置好；
community.oracle.com/thread/2487613 (看连接是去掉前"https://",我没权限发链接)
1、备份现有的multipath.conf
mv -f /etc/multipath.conf multipath.conf_old
2、重新生成并填充multipath.conf内容
cat > multipath.conf <<EOF
defaults {
user_friendly_names yes
}

devices {
device {  
vendor "(COMPAQ|HP)"
product "HSV1[01]1|HSV2[01]0|HSV300|HSV4[05]0"
#getuid_callout "/lib/udev/scsi_id --whitelisted --device=/dev/%n"
features "0"
hardware_handler "0"
path_selector "round-robin 0"
path_grouping_policy group_by_prio
failback immediate
rr_weight uniform
no_path_retry 12
rr_min_io 1000
path_checker tur
prio alua
}
}

#blacklist {
# devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
# devnode "^hd[a-z]"
# devnode "^dcssblk[0-9]*"
#}
EOF
我的getuid_callout一项报错，我将其注释掉了
Aug 11 09:14:30 | multipath.conf +9, invalid keyword: getuid_callout
3、重新启动服务器后运行正常
systemctl stop multipathd.service
systemctl start multipathd .service
multipath -ll
ll /dev/mapper
都出来了，比较兴奋！
