1、如果之前有配置好的服务器端连接，现在客户端不想用之前的连接了，CentOS5.6 下清除非常简单，按照如下方法卸载。
1）停止服务service iscsi stop
2）去除挂载iscsiadm -m node –op delete
3）重启服务[root@rac1 send_targets]# service iscsi restartStopping iSCSI daemon:iscsid is stopped [ OK ]Starting iSCSI daemon: [ OK ] [ OK ]Setting up iSCSI targets: iscsiadm: No records found! [ OK ] 2、配置客户端
1）正确配置openfiler，，请一定要严格按照文档，不要遗漏任何一步。
2）扫描[root@ ~]# iscsiadm -m discovery -t sendtargets -p 172.100.10.100172.100.10.100:3260,1 iqn.2006-01.com.openfiler:LUN2172.100.10.100:3260,1 iqn.2006-01.com.openfiler:LUN1
3）重启服务service iscsi restart
4）可以看到目录[root@rac1 ~]# fdisk -l
