安装:scsi-target-utils.i386 : The SCSI target daemon and utility programs
文档:more /usr/share/doc/scsi-target-utils-0.0/README.iscsi
设置:

chkconfig tgtd on

查看target状态
tgt-admin -s

写入配置文件
tgt-admin –dump > /etc/tgt/targets.conf

刷新配置，删除、离线、在线、更新target对应
tgt-admin -e ALL
tgt-admin –delete ALL
tgt-admin –offline ALL
tgt-admin –ready ALL
tgt-admin –update ALL

直接输入这些命令是对所有生效，后面也可以接target名称，或者跟help
tgt-admin -e help

可以用-p让其转换成为tgtadm的命令
tgt-admin –update -p
