在linux和Windows下配置HP FC存储设备多路径驱动

2024-08-03 03:59:18 223人阅读

主机安装HBA卡驱动，一般光纤卡的厂家就是QLogic和Emulex的。

Linux下查看光纤卡驱动模块是否加载通过

lsmod |grep qla2xxx #查看是否加载了QLogic的光纤卡模块
lsmod |grep lpfc #查看是否加载了Emulex的光纤卡模块
modprobe lpfc  #加载相应的光纤卡模块

Windows下查看设备管理器查看是否加载了驱动（如果没有的话安装相应的光纤卡驱动）。

2. 查看光纤卡的WWN号（记录下来为存储设备映射时使用）

Linux

more /sys/class/fc_host/host1/node_name #根据光纤卡端口的数量可能会有host1，host2等。

Windows

wmic /namespace:\\root\wmi path MSFC_FCAdapterHBAAttributes get /value #查看PortWWN号码，是10进制的，需要转换到16进制（其实一般只需要把最后的号码转换一下，在存储设备中能够识别出来是那台主机即可）

3. 存储设备映射卷到主机

FC存储设备是通过WWN号来识别主机的，此处把划出来的卷分配给相应主机的WWN号码即可。

4. 安装多路径软件

Linux

yum list |grep device-mapper          #查找多路径包
yum install device-mapper-multipath   #CentOS下安装多路径软件

suse 通过yast或zypper安装，Ubuntu 通过 apt-get安装。两个包：device-mapper和device-mapper-multipath包。搜索一下安装这两个包，名字各版本可能有差别。

Windows 2008以上

服务器管理--功能--添加功能--选择Multipath IO包安装。然后选择管理员工具-MPIO--发现多路径选项卡--添加即可，重启后即可看到效果。

5. Linux多路径配置文件

centos 5.x

修改/etc/multipath.conf

其实各Linux发行版都是使用Redhat开发的multipath包，只是有些命令的位置不同而已。修改一下就可以适用与各linux系统。

具体的配置参数信息请参考：

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/

6. Linux 配置多路径命令

centos 5.x

chkconfig --list|grep multipathd #查看多路径服务是否开机启动
chkconfig multipathd on #开机打开多路径服务
service multipathd start #打开多路径服务
multipath  #配置多路径 -vn n为数字，可以显示更多信息
multipath -ll #查看多路径设备和信息

其他

multipath 
multipath -ll

在启用了user_friendly_names配置后设备名为 /dev/mapper/mpathn,其中n为字母，这个是udev映射的可使用的设备，不要直接操作 /dev/dm-n 或是 /dev/mpath/mpathn，因为它们为系统所使用。

7. 排错

multipathd -k #进入交互模式，具体请查看 man multipathd
>list|show config
>reconfigure
>list|show path

小技巧：当存储添加了新的映射时，我们可以使用下面的命令让系统重新识别设备而无需重启。

echo 1 >/sys/class/fc_host/host0/issue_lip
echo 1 >/sys/class/fc_host/host1/issue_lip
echo "- - -" >/sys/class/scsi_host/host0/scan
echo "- - -" >/sys/class/scsi_host/host1/scan
