Addressing
Special names refer to both iSCSI initiators and targets. iSCSI provides three name-formats:
- iSCSI Qualified Name (IQN)
- Format: The iSCSI Qualified Name is documented in RFC 3720, with further examples of names in RFC 3721. Briefly, the fields are:
-
- literal iqn
- date (yyyy-mm) that the naming authority took ownership of the domain
- reversed domain name of the authority (org.alpinelinux, com.example, to.yp.cr)
- Optional ":" prefixing a storage target name specified by the naming authority.
- From the RFC:
Naming String defined by
Type Date Auth "example.com" naming authority
