################登陆服务器检测服务器信息################
1)检查用户登录信息
[root@CNZHAPLAMC138 ~]# id
uid=0(root) gid=0(root) groups=0(root)
2)同步服务器时间
[root@CNZHAPLAMC138 ~]# ntpdate 10.10.6.101
23 May 21:55:37 ntpdate[72045]: step time server 10.10.6.101 offset 448.347362 sec
[root@CNZHAPLAMC138 ~]# hwclock –w
[root@CNZHAPLAMC138 ~]# date
##################对linux服务器作存储映###############
1)查看光纤卡标识
[root@CNZHAPLAMC138 fc_host]# cd /sys/class/fc_host/host15/
[root@CNZHAPLAMC138 host15]# cat port_name
0x100000109b341bc8
[root@CNZHAPLAMC138 fc_host]# cd /sys/class/fc_host/host16/
[root@CNZHAPLAMC138 host15]# cat port_name
0x100000109b341bc4
2）将光纤卡标识输入到存储LUN启动程序组
1.浏览器中打开10.10.6.166温备存储
2.点击LUN启动程序组
3.点击编辑
4.启动程序
5.把得到port_name标识输入给启动程序
3）LUN ID 输入映射存储对应的服务器中
1.查找LUN ID
2.点击准备映射的存储LUN
3.对LUN点击编辑程序组将LUNid放到对应的服务器中
4.填写对应的服务器名称

##########查看linux磁盘分区#############
[root@CNZHAPLAMC138 class]# lvmdiskscan
####################多路径multipathd配置##############
1)mpathconf配置文件生成以及检查mathconf服务是否开启
[root@CNZHAPLAMC138 class]# /sbin/mpathconf
2)初始化DM
[root@CNZHAPLAMC138 class]# modprobe dm-multipath
[root@CNZHAPLAMC138 class]# modprobe dm-round-robin
[root@CNZHAPLAMC138 class]# systemctl start multipathd
3）修改multipath配置文件
[root@CNZHAPLAMC138 etc]# cd /usr/share/doc/device-mapper-multipath-0.4.9/
[root@CNZHAPLAMC138 device-mapper-multipath-0.4.9]# vim multipath.conf
############添加以下内容
multipaths {
multipath {
wwid 3600a09803830447967244c61626d6e2f
alias o3db
path_grouping_policy multibus #failover
#path_checker readsector0
path_selector "round-robin 0"
failback immediate
}
multipath {
wwid 3600a09803830447967244c61626d6e59
alias o3app
path_grouping_policy multibus #failover
#path_checker readsector0
path_selector "round-robin 0"
failback immediate
}
multipath {
wwid 3600a09803830447967244c61626d6e63
alias fbapp
path_grouping_policy multibus #failover
#path_checker readsector0
path_selector "round-robin 0"
failback immediate
}
}
3）将此文件复制到修改后的文件复制到 /etc
[root@CNZHAPLAMC138] device-mapper-multipath-0.4.9]# cp multipath.conf /etc
4)查看多路径服务启用状态
[root@CNZHAPLAMC138 class]# systemctl status multipathd
5)重新刷取 multipath
[root@CNZHAPLAMC138 /]# multipath -v2
6)重新加载multipath配置文件模块
[root@CNZHAPLAMC138 /]# multipath -ll
7)进到/dev/mapper进行查看映射成功的LUN名称
[root@CNZHAPLAMC138 /]#cd /dev/mapper
[root@CNZHAPLAMC138 mapper]# ls -ltr
