ISCSID

 

1. 服务端安装软件包。
rpm -ivh perl-Config-General-2.40-1.el5.rf.noarch.rpm
rpm -ivh scsi-target-utils-0.0-5.20080917snap.el5.i386.rpm

２.　创建LV。
for i in {1..18}; do lvcreate -L 1G -n scsi_$i VolGroup00; done

３.　修改配置文件。

４.　启动服务。
service tgtd start

５.　查看共享出去的盘。
tgtadm --lld iscsi --op show --mode target

６.　查看端口：

netstat -ntlup


客户端配置：

1.coplish a bash shell script and perfmed the script

#!/bin/bash
rpm -ivh iscsi-initiator-utils-6.2.0.871-0.10.el5.i386.rpm &>/dev/null
service iscsid start
chkconfig iscsid on

iscsiadm --mode discovery --type sendtargets --portal 192.168.0.16
echo "add storage with command"
echo 'iscsiadm --mode node --targetname iqn.2011-12.com.example:scsi_X --portal 192.168.0.16:3260 --login'

2.perfermed 
iscsiadm --mode node --targetname iqn.2011-12.com.example:scsi_1 --portal 192.168.0.16:3260 --login
