If you set the storage or storage_6 flag to yes, the IPv4 or IPv6 address for the port can be used to establish connections to the backend iSCSI controller. After you use the addiscsistorageport command to establish connectivity from the source port to one or more backend controllers, then you cannot set the storage or storage_6 flag to no unless all the sessions to backend controllers are removed.
Verify the information, make a correction, and resubmit the command.
