liunx系统下iscsi存储设备的挂载方法

CentOS配置邦诺存储iscsi卷指导手册

具体步骤如下：

1、查看并安装iscsi程序包；

#mkdir /mnt/cdrom （挂载CentOS系统光盘）

#mount -t auto /dev/cdrom /mnt/cdrom

#cd /mnt/cdrom

#cd .. /RPMS

#rpm -ivh iscsi-initator***.rpm

2、连接iscsi盘；

[root@serverKK ~]#

[root@serverKK ~]# iscsiadm -m discovery -t sendtargets -p 172.18.16.141:3260

//建立linux服务器与存储的iscsi连接, 粗体部分为存储的IP地址

iscsiadm: This command will remove the record [iface: default, target: iqn.2004-05.storos.t-141, portal: 172.18.16.141,3260], but a session is using it. Logout session then rerun command to remove record.

172.18.16.141:3260,1 iqn.2004-05.storos.t-141

172.18.16.141:3260,1 iqn.2004-05.storos.t-142 //正常建立的iscsi连接记录

[root@serverKK ~]# iscsiadm -m node //查看已经建立的iscsi连接

172.18.16.139:3260,1 iqn.2004-05.storos.t-9

172.18.16.139:3260,1 iqn.2004-05.storos.t-139

172.18.16.141:3260,1 iqn.2004-05.storos.t-141

172.18.16.141:3260,1 iqn.2004-05.storos.t-142

[root@serverKK ~]# iscsiadm -m node –T iqn.2004-05.storos.t-142 -p 172.18.16.141:3260 -l //激活已经建立的iscsi连接，如粗体部分和查看到iscsi连接记录相同。

Logging in to [iface: default, target: iqn.2004-05.storos.t-142, portal: 172.18.16.141,3260]

Login to [iface: default, target: iqn.2004-05.storos.t-142, portal: 172.18.16.141,3260]: successful

3、查看已经挂接的iscsi盘并作本地系统格式化；

[root@serverKK ~]# fdisk -l //查看linux系统的物理盘

Disk /dev/sda: 73.4 GB, 73407488000 bytes

255 heads, 63 sectors/track, 8924 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/sda1 * 1 13 104391 83 Linux

/dev/sda2 14 8924 71577607+ 8e Linux LVM

Disk /dev/sdb: 73.4 GB, 73407488000 bytes

255 heads, 63 sectors/track, 8924 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/sdb1 * 1 8924 71681998+ 8e Linux LVM

Note: sector size is 4096 (not 512)

Disk /dev/sdc: 5989.9 GB, 5989969428480 bytes

255 heads, 63 sectors/track, 91029 cylinders

Units = cylinders of 16065 * 4096 = 65802240 bytes

Disk /dev/sdc doesn't contain a valid partition table

Note: sector size is 4096 (not 512)

Disk /dev/sdd: 5996.5 GB, 5996512542720 bytes

255 heads, 63 sectors/track, 91129 cylinders

Units = cylinders of 16065 * 4096 = 65802240 bytes

Disk /dev/sdd doesn't contain a valid partition table

Disk /dev/sde: 5996.5 GB, 5996512542720 bytes

255 heads, 63 sectors/track, 729034 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sde doesn't contain a valid partition table

#mkfs.ext3 /dev/sde

#mkdir /mnt/iscsi

#mount /dev/sde /mnt/iscsi

4、自动挂载iscsi卷，（挂载多块iscsi盘，写多次就可以了）

#vi /etc/rc.local

在最后一行添加

iscsiadm -m node –T iqn.2004-05.storos.t-142 -p 172.18.16.141:3260 -l sleep 5 （休眠时间）

mount /dev/sde /mnt/iscsi

保存之后重启系统。
