Linux挂载iscsi存储

1、检查iscsi rpm包

rpm -qa | grep iscsi

安装rpm包

[root@qionghai11g Packages]# rpm -Uvh iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm

2、启动iscsi服务并设置开机自启动

[root@qionghai11g Packages]# service iscsi start

[root@qionghai11g Packages]# chkconfig --list | grep iscsi

3、查找存储对外提供的逻辑卷

[root@qionghai11g ~]# iscsiadm -m discovery -t sendtargets -p 192.16.10.188:3260

Starting iscsid:                                           [  OK  ]

192.16.10.188:3260,1 iqn.2004-01.com.storbridge:block02-wt

192.16.10.188:3260,1 iqn.2004-01.com.storbridge:block01-wt

4、映射逻辑卷到Linux系统中

[root@qionghai11g ~]# iscsiadm -m node -T iqn.2004-01.com.storbridge:block01-wt -p 192.16.10.188:3260 -l

Logging in to [iface: default, target: iqn.2004-01.com.storbridge:block01-wt, portal: 192.16.10.188,3260] (multiple)

Login to [iface: default, target: iqn.2004-01.com.storbridge:block01-wt, portal: 192.16.10.188,3260] successful.

[root@qionghai11g ~]# iscsiadm -m node -T iqn.2004-01.com.storbridge:block02-wt -p 192.16.10.188:3260 -l

Logging in to [iface: default, target: iqn.2004-01.com.storbridge:block02-wt, portal: 192.16.10.188,3260] (multiple)

Login to [iface: default, target: iqn.2004-01.com.storbridge:block02-wt, portal: 192.16.10.188,3260] successful.

5、设置开机自动映射

[root@qionghai11g ~]# iscsiadm -m node -T iqn.2004-01.com.storbridge:block02-wt -p 192.16.10.188:3260 --op update -n node.startup -v automatic

[root@qionghai11g ~]# iscsiadm -m node -T iqn.2004-01.com.storbridge:block01-wt -p 192.16.10.188:3260 --op update -n node.startup -v automatic

这两个是开机自动映射

6、对映射出来的磁盘进行分区

由于存储容量是12T 大于2T，不能用不同分区 fdisk ，只能用GPT分区

parted /dev/sdb  对/dev/sdb进行分区

print     打印信息，从中可以看出这个磁盘大小和分区格式

mklabel gpt   

mkpart primary 0% 100%

print    从中可以看出这个磁盘分区格式已经变了成GPT了

7、分区之后进行格式化

[root@oracle11g ~]# mkfs.ext3 /dev/sdb

mke2fs 1.39 (29-May-2006)

/dev/sdb is entire device, not just one partition!

Proceed anyway? (y,n) y

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

This filesystem will be automatically checked every 23 mounts or

180 days, whichever comes first.  Use tune2fs -c or -i to override.

8、挂载分区

[root@qionghai11g ~]# cd /var/www/html/

[root@qionghai11g html]# mkdir kk1 kk2

[root@qionghai11g mnt]# mount  /dev/sdb1 /var/www/html/kk1/
