However, for security reasons the iSCSI target may prevent logons from a single IP address using multiple Initiator Names, and therefore some logon attempts may fail.

What happens when the initiator name is changed in iSCSI?

When the Initiator Name is changed in the iSCSI Initiator Properties, any pre-existing Favorite Target entries should be removed and recreated to ensure they use the new Initiator Name. Also, ensure the Initiator Name always matches the Initiator Name that the iSCSI target is using for access control.
