使用iSCSI存储时报错（openfiler模拟）

[root@single Packages]# iscsiadm -m discovery -t st -p 192.168.188.2
iscsiadm: cannot make connection to 192.168.188.2: Connection refused
iscsiadm: cannot make connection to 192.168.188.2: Connection refused
iscsiadm: cannot make connection to 192.168.188.2: Connection refused

解决：到openfiler服务器上

[root@lmopenfiler ~]# vi /etc/initiators.deny 

# PLEASE DO NOT MODIFY THIS CONFIGURATION FILE!

</span>

# End of Openfiler configuration

重启了一下服务器，搞定：
[root@single Packages]# iscsiadm -m discovery -t st -p 192.168.188.2
192.168.188.2:3260,1 iqn.1994-05.com.redhat:69fabc5d25f
