iSCSI的简单设置与挂载

实验平台：CentOS-6.0 VM with Linux2.6.32

依赖的包：iscsi-initiator-utils，scsi-target-utils

 

启动target服务

[root@viking-vm ~]# /etc/init.d/tgtd start

[root@viking-vm ~]# chkconfig tgtd on

新建一个iSCSI target

[root@viking-vm ~]# tgtadm --lld iscsi --op new--mode target --tid 1 -T t1.iscsi.andrew.org [root@viking-vm ~]# tgtadm --lldiscsi --op show --mode target

Target 1: t1.iscsi.andrew.org

    Systeminformation:

       Driver: iscsi

       State: ready

    I_Tnexus information:

    LUNinformation:

       LUN: 0

            Type: controller

           SCSI ID: IET     00010000

           SCSI SN: beaf10

           Size: 0 MB

           Online: Yes

           Removable media: No

           Backing store type: rdwr

           Backing store path: None

    Accountinformation:

    ACLinformation:

 

当前挂载的块设备

[root@viking-vm ~]# ls /dev/sd*

/dev/sda /dev/sda1  /dev/sda2  /dev/sdb

 

[root@viking-vm ~]# tgtadm --lld iscsi --op new--mode logicalunit --tid 1 --lun 1 -b /dev/sdb

[root@viking-vm ~]# tgtadm --lld iscsi --op show--mode target

Target 1: t1.iscsi.andrew.org

    Systeminformation:

       Driver: iscsi

       State: ready

    I_Tnexus information:

    LUNinformation:

       LUN: 0

           Type: controller

           SCSI ID: IET     00010000

            SCSI SN: beaf10

           Size: 0 MB

           Online: Yes

           Removable media: No

           Backing store type: rdwr

           Backing store path: None

       LUN: 1

           Type: disk

           SCSI ID: IET     00010001

            SCSI SN: beaf11

           Size: 10737 MB

           Online: Yes

           Removable media: No

           Backing store type: rdwr

           Backing store path: /dev/sdb

    Accountinformation:

    ACLinformation:

[root@viking-vm ~]# tgtadm --lld iscsi --op bind--mode target --tid 1 –i ALL

 

远程挂载iscsi块设备，本例中是在本地挂载的，远程是一样的，都是使用的iSCSI协议

[root@viking-vm ~]# iscsiadm -m discovery -tsendtargets -p 10.0.0.81

Starting iscsid:                                          [  OK  ]

10.0.0.81:3260,1 t1.iscsi.andrew.org

[root@viking-vm ~]#  iscsiadm -m node -T t1.iscsi.andrew.org -p10.0.0.81 --login

Logging in to [iface: default, target:t1.iscsi.andrew.org, portal: 10.0.0.81,3260]

Login to [iface: default, target:t1.iscsi.andrew.org, portal: 10.0.0.81,3260] successful.

 

可以看出本地多了一块块设备，挂载成功

[root@viking-vm ~]# ls /dev/sd*

/dev/sda /dev/sda1  /dev/sda2  /dev/sdb /dev/sdc
