Hi @Jackiez ,
NetApp ONTAP only supports IEEE standard format.
- Most Operating Systems (OS) will allow users to rename iSCSI Qualified Name's (IQN).
- NetApp ONTAP requires that IQNs match the IEEE standard in order to connect to the storage system.
- Host IQNs can be renamed; however, in order to operate with NetApp controllers they must follow this standard.
The standard is as follows:
iqn.yyyy-mm.reverse_domain_name:any_friendly_name
For example, iqn.1991-05.com.microsoft:winclient1 OR iqn.1991-05.com.microsoft:winclient2
- NetApp also supports the EUI-64 type IQN which takes the format - EUI.64bit_address
For example, eui.02004567A425678D
- IQNs that do not conform to one of these standards will not work with NetApp.
For example, dashes are allowed in IQN names. Underscores are not allowed.

If you can work with the above IQN naming standards you can change the iSCSI target name on ONTAP 9 NetApp storage system following this KB https://kb.netapp.com/on-prem/ontap/da/SAN/SAN-KBs/How_to_modify_iSCSI_target_name_on_ONTAP
