When you create an iSCSI Target with the Microsoft iSCSI Target software, you create devices and assign them to an iSCSI Target.
The problem is that you need to tell the target which clients are allowed to connect—which by default is no one. Select the properties of the iSCSI target and, under the iSCSI Initiators tab, click Add and select the IQNs of the clients who are allowed to connect. The IQNs of clients that have tried to connect in the past will be displayed, or you can manually type the IQN of the allowed clients. The clients should now be able to connect.
If you're unsure of the IQN of an iSCSI Initiator (the client), launch the iSCSI Initiator Administrator Tool application on the client. Under the Configuration tab, its IQN is shown.
E explicou que a guia de iniciadores iSCSI no Target deve estar correta. Então eu chequei meu IQN novamente e sim eu gordo com ele! Depois de entrar no endereço correto, a conexão foi um fato!
