redhat创建并挂载scsi磁盘测试
实验设备：
用虚拟机虚拟两个 redhat linux 6.3 -64bit 系统，并配置好yum
ip设置：
scsi服务端：10.1.1.222
scsi客户端（挂载端）：10.1.1.1
实验开始：
1、在服务端安装软件并配置好共享的磁盘，首先在虚拟机中新加入一块硬盘，大小随意。
（这里添加100G）
[root@localhost ~]# fdisk -l
Disk /dev/sda: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0005bb6c
Device Boot Start End Blocks Id System
/dev/sda1 * 1 26 204800 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 26 281 2048000 82 Linux swap / Solaris
Partition 2 does not end on cylinder boundary.
/dev/sda3 281 2611 18717696 83 Linux
Disk /dev/sdb: 107.4 GB, 1 bytes
255 heads, 63 sectors/track, 13054 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00077087
Device Boot Start End Blocks Id System
2、安装scsi服务端软件
yum install scsi-target-utils -y
共享磁盘（在配置文件中加入以下代码即可）
vim /etc/tgt/
backing-store /dev/sdb
启动服务
1 service tgtd restart
关闭防火墙和selinux
3、在客户端安装客户端软件，并设置挂载
安装客户端软件
yum install iscsi-initiator-utils -y
查看是否有共享磁盘
iscsiadm --mode discoverydb --type sendtargets --portal 10.1.1.222 --discover
出现以下则表示有共享磁盘 10.1.1.222:3260,1 e:1
挂载磁盘
iscsiadm --mode node --targetname e:1 --portal 10.1.1.222:
3260 --login
注意：中间2008-09这段是填写上面查询出来的那个磁盘名
成功挂载后有以下提示
[root@localhost ~]# iscsiadm --mode node --targetname e:
1 --portal 10.1.1.222:3260 --login
Logging in to [iface: default, target: e:1, portal: 10.1.1.222,3
260] (multiple)
Login to [iface: default, target: e:1, portal: 10.1.1.222,3260]
successful.
查看以下挂载成功没有
[root@localhost ~]# fdisk -l
Disk /dev/sda: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00036380
Device Boot Start End Blocks Id System
/dev/sda1 * 1 26 204800 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 26 281 2048000 82 Linux swap / Solaris
Partition 2 does not end on cylinder boundary.
/dev/sda3 281 2611 18717696 83 Linux
Disk /dev/sdb: 107.4 GB, 1 bytes
255 heads, 63 sectors/track, 13054 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00077087
Device Boot Start End Blocks Id System
成功挂载100G硬盘。
实验结束
