linux下san存储多路径软件的安装及配置

1、linux下，san存储多路径软件的安装及配置redhat 5.4链路聚合需要的 2个软件分别在安装光盘的server目录下面device-mapper-L02.32-l.el5.x86_64.rpmdevice- inapper-miiltiph-0A7-30 占 I 5,k86_ &4. rpm安装完毕后应该包括下面的软件包qa| grep devicedevi ce-mapper-roultipath0. 4. 7-17 el5devi ce-mapper-event-1. 02. 24-1. el5devicemap-per 1 02. 24-1 el5linux下，san存储

2、多路径软件的配置1、 使用ntsysv命令将mulitipath服务开启* multipathd2、启动该服务rootmail in it.d# service multipathd startStarting multipathd daem on:3、修改配置文件 /etc/multipath.confvi /etc/multipath.c onf# This is a basic configuration file with some examples, for device mapper# multipath.# For a complete list of the default c

3、onfiguration values, see# /usr/share/doc/device-mapper-multipath-0.4.7/multipath.c on f.defaults# For a list of configuration options with descriptions, see# /usr/share/doc/device-mapper-multipath-0.4.7/multipath.conf.annotated# Blacklist all devices by default. Remove this to enable multipathing# o

4、n the default devices.blacklist color=Red# devnode "*"/color# By default, devices with vendor = "IBM" and product = "S/390.*" are # blacklisted. To enable mulitpathing on these devies, uncomment the # following lines.#blacklist_exceptions 4、使用 multipath -F删除现有路径5、multip

5、ath -v2格式化路径6、使用 multipath -ll查看多路径rootmail /# multipath -llmpath0 (3600508b40006ea6e0001a000002a0000) dm-2 HP,HSV210 size=500Gfeatures=1 queue_if_no_pathhwhandler=0_ round-robin 0 prio=100active_ 0:0:2:1 sdc 8:32 activeready_ 0:0:3:1 sdd 8:48 activeready_ round-robin 0 prio=20enabled_ 0:0:0:1 sda 8
