################登陸服務器檢測服務器信息################
1)檢查用戶登錄信息
[root@CNZHAPLAMC138 ~]# id
uid=0(root) gid=0(root) groups=0(root)
2)同步服務器時間
[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
##################對linux服務器作存儲映###############
1)查看光纖卡標識
[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）將光纖卡標識輸入到存儲LUN啟動程序組
1.瀏覽器中打開10.10.6.166溫備存儲
2.點擊LUN啟動程序組
3.點擊編輯
4.啟動程序
5.把得到port_name標識輸入給啟動程序
3）LUN ID 輸入映射存儲對應的服務器中
1.查找LUN ID
2.點擊准備映射的存儲LUN
3.對LUN點擊編輯程序組將LUNid放到對應的服務器中
4.填寫對應的服務器名稱

####################多路徑multipathd配置##############
1)mpathconf配置文件生成以及檢查mathconf服務是否開啟
[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
############添加以下內容
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）將此文件復制到修改后的文件復制到 /etc
[root@CNZHAPLAMC138] device-mapper-multipath-0.4.9]# cp multipath.conf /etc
4)查看多路徑服務啟用狀態
[root@CNZHAPLAMC138 class]# systemctl status multipathd
5)重新刷取 multipath
[root@CNZHAPLAMC138 /]# multipath -v2
6)重新加載multipath配置文件模塊
[root@CNZHAPLAMC138 /]# multipath -ll
7)進到/dev/mapper進行查看映射成功的LUN名稱
[root@CNZHAPLAMC138 /]#cd /dev/mapper
[root@CNZHAPLAMC138 mapper]# ls -ltr
