user defined openstack iqn with ONTAP

Hi, Experts,

We met an issue when connect A800 to customer's openstack platform, customer uses iscsi protocol and self defined iqn format, but ONTAP just support standard iqn format. Customer can't change iscsi network. So any way to solve the issue ?

Thanks for your adivce !

Rgds,

Jackie

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
