Every iSCSI node must have a node name. Node names typically take the iSCSI Qualified Name (IQN) format. This standard is industry standard and required by NetApp. The IQN-type designator is a logical name that is not linked to an IP address.
The following is an example format:
yyyy-mm is the month and year in which the naming authority acquired the domain name.
'backward-naming-authority' is the reverse domain name of the entity responsible for naming this device. An example reverse domain name is 'com.microsoft'.
'unique-device-name' is a free-format unique name for this device assigned by the naming authority.
The following example shows the iSCSI node name for an initiator that is an application server:
Note: Some initiators might provide variations on the preceding format.
An iSCSI initiator node name is used when associating an iSCSI host with a Data ONTAP initiator group (igroup) for the purpose of mapping a LUN to the host.
