1、如果之前有配置好的服務器端連接，現在客戶端不想用之前的連接了，CentOS5.6 下清除非常簡單，按照如下方法卸載。
1）停止服務
service iscsi stop
2）去除掛載
iscsiadm -m node --op delete
3）重啟服務
[root@rac1 send_targets]# service iscsi restart
Stopping iSCSI daemon:
iscsid is stopped [ OK ]
Starting iSCSI daemon: [ OK ]
[ OK ]
Setting up iSCSI targets: iscsiadm: No records found!
[ OK ]
2、配置客戶端
1）正確配置openfiler，請一定要嚴格按照文檔，不要遺漏任何一步。
2）掃描
[[email protected] ~]# iscsiadm -m discovery -t sendtargets -p 172.100.10.100
172.100.10.100:3260,1 iqn.2006-01.com.openfiler:LUN2
172.100.10.100:3260,1 iqn.2006-01.com.openfiler:LUN1
3）重啟服務
service iscsi restart
4）可以看到目錄
[root@rac1 ~]# fdisk -l

結束了。。。哈哈就是這麼簡單
