Mostly, virtualization softwares will take care MAC addresses during cloning, but they may not take care the initiator name. Therefore, we should also change the initiator name.
Assuming that the initiator name of the newly cloned VM is empty, we can get another random generated name for your new name.
[root@test2 ~]# /sbin/iscsi-iname
Let's modify the initiator by the new name.
[root@test2 ~]# vi /etc/iscsi/initiatorname.iscsi
Please restart the iscsi service.
[root@test2 ~]# service iscsi restart
Now, there won't be initiator conflicts on the storage server.
