##    2.2 安装tgt ##

在sheepdog 任一节点上安装tgt

$ git clone git://github.com/fujita/tgt.git -b sheepdog
    $ cd tgt
    $ make
    # make install

##       2.3 配置tgtd ##

启动tgtd

#tgtd

创建target

# tgtadm --op new --mode target --tid 1 --lld iscsi -T iqn.2001-04.com.example:storage.sr.rose.sys1.xyz

创建lun

#tgtadm --op new --mode logicalunit --tid 1 --lun 1 -b iscsivol --bstype sheepdog

访问权限

# tgtadm --lld iscsi --op bind --mode target --tid 1 -I ALL

查看tgt target配置
