What is WWN in SAN switch?
SAN-connected devices are identified by a unique identifier, known as the WWN (or world wide name). Switch WWN identifiers are a 64-bit number that has eight colon-separated fields each consisting of one or two hexadecimal digits between 0 and ff.
What does a WWN look like?
Each WWN is an 8- or 16-byte number, the length and format of which is determined by the most significant four bits, which are referred to as an NAA (Network Address Authority). “Original” IEEE formats are essentially a two-byte header followed by an embedded EUI-48 address (which contains the OUI).

What is a SAN switch used for?
A storage area network (SAN) switch is a device that connects servers and shared pools of storage devices and is dedicated to moving storage traffic. SAN switches make it possible to build vast high-speed storage networks that interconnect thousands of servers accessing petabyte-scale data.
What do you need to know about switch WWN?
Switch WWN identifiers are a 64-bit number that has eight colon-separated fields each consisting of one or two hexadecimal digits between 0 and ff. The WWN is a factory-set parameter that cannot be changed by the end user. The WWN is used as the license ID in many cases but that can be vendor specific.
What does a switch WWN identifier look like?
On the surface a WWN identifier may not look very useful, but broken down into its component parts, more information is available. Switch WWN identifiers are a 64-bit number that has eight colon-separated fields each consisting of one or two hexadecimal digits between 0 and ff.
How to change the WWNs in the alias?
1. Change only one HBA port at a time 2. See the login to the switch with new WWNs 3. Insert the new WWNs in the alias/zones/zonset (cfgsave/cfgenable) – commands needed for all, and once we insert the new WWN in alias , we can enable the configuration (cfgenable), right? or we need to check the zones as well?? 4.
Which is the OUI component of the switch WWN?
The 10:00 component of the WWN will either be hex 10:00 or 2x:xx (where the x’s are vendor-specified) The 00:27:F8 component is the “Organizationally Unique Number” or OUI. This is a number that is purchased by the switch vendor from the Institute of Electrical and Electronics Engineers (IEEE) Registration Authority.
