For SLES10, a unique number is created during RPM installation. See page 33 of RFC 3720 (188.8.131.52.1. Type "iqn." (iSCSI Qualified Name)): The iSCSI qualified name string consists of: - The string "iqn.", used to distinguish these names from "eui." formatted names. - A date code, in yyyy-mm format. This date MUST be a date during which the naming authority owned the domain name used in this format, and SHOULD be the first month in which the domain name was owned by this naming authority at 00:01 GMT of the first day of the month. This date code uses the Gregorian calendar. All four digits in the year must be present. Both digits of the month must be present, with January == "01" and December == "12". The dash must be included. - A dot "." - The reversed domain name of the naming authority (person or organization) creating this iSCSI name. - An optional, colon (:) prefixed, string within the character set and length boundaries that the owner of the domain name deems appropriate. This may contain product types, serial numbers, host identifiers, or software keys (e.g., it may include colons to separate organization boundaries). With the exception of the colon prefix, the owner of the domain name can assign everything after the reversed domain name as desired. It is the responsibility of the entity that is the naming authority to ensure that the iSCSI names it assigns are worldwide unique. For example, "Example Storage Arrays, Inc.", might own the domain name "example.com". > initiatorname is supposed to be unique?right? Yes!
