About the iSCSI Qualified Name (IQN)

In an iSCSI network, each iSCSI element that uses the network has a unique iSCSI name and is assigned an address for access. Each iSCSI element, whether an initiator or target, is identified by a unique iSCSI Qualified Name (IQN). The IQN is a logical name that is not linked to an IP address.

The IQN has the following properties:

  • It is unique. No two initiators or targets can have the same name.

  • It can be up to 255 characters long.

  • It can only contain numbers (0-9), letters (A-Z and a-z), colons (:), hyphens (-), and periods (.).

A sample IQN format is iqn.yyyy-mm.naming-authority:unique name where:

  • yyyy-mm is the year and month when the naming authority was established.

  • naming-authority is usually reverse syntax of the Internet domain name of the naming authority.

  • Unique name is any name you want to use, for example, the name of your host. The naming authority must make sure that any names assigned following the colon are unique.
