HP Fabric OS 6.2.2f Release Notes (5697-1756, February 2012)

New OUI Support on B-Series platforms
Overview
The OUI (Organizationally Unique Identifier) value is part of a Fibre Channel WWN that uniquely
identifies the manufacturer of Fibre Channel products. The OUI values assigned to Brocade are
used by Fabric OS to validate certain fabric interoperability support.
The currently assigned OUI/WWN values are nearing exhaustion, necessitating Brocade to use
a new OUI value for WWN assignment. The new OUI value for Brocade is 00:05:33. A WWN
of 10:00:00:05:33:41:5c:c1, for example, demonstrates the usage of the new OUI. WWNs
with the current OUI value are expected to be consumed by mid-2010. Brocade factory shipments
of switches after this time will have WWNs that include the new OUI.
Fabric OS 6.2.2b has been enhanced to recognize the new Brocade OUI value to guarantee
proper functionality. It is important to note that no switch with the new OUI/WWN should be
downgraded to a version of Fabric OS that does not recognize this new OUI. It is also important
to note that specific minimum requirements for recognition of the new OUI will neither be validated
nor enforced by Fabric OS.
Impact of products with the new OUI to existing fabrics/environments
In most situations, a switch that uses the new OUI can be seamlessly added to an existing fabric,
even if the other switches in that fabric are not using Fabric OS versions that are aware of the new
OUI value. However, there are some exceptions and limitations to consider before adding a switch
utilizing the new OUI to an existing fabric or environment.
• Fabrics with encryption products: If an HP StorageWorks encryption switch or blade using the
new OUI is added to an edge fabric of a Fibre Channel routed fabric, Frame Redirection
capability could be impacted across the FCR backbone, thus impacting the encryption
functionality. Therefore, the FC routers in the FCR backbone fabric will need to be upgraded
to a firmware version that supports the new OUI.
• Interopmode 2 and 3 fabrics: In an interopmode 2 or 3 fabric with VE ports, the switches on
both ends of the VE link must run a firmware version that supports the new OUI, or the VE
ports may not function correctly, resulting in unpredictable behavior.
HP Network Advisor compatibility
Fabric OS 6.2.2f is fully compatible with HP Network Advisor 11.1.x management software.
Network Advisor is a comprehensive SAN management application that enables end-to-end
management of HP B-series Data Center Fabrics. It is the next-generation product and the successor
to Data Center Fabric Manager (DCFM).
HP Network Advisor is available in three versions (see the HP Network Advisor release notes for
full support details):
• HP Network Advisor Professional—An application bundled with B-series switches that is ideally
suited for small- and medium-size businesses that need a lightweight management product to
manage their smaller fabrics (one physical fabric at a time, up to 1,000 ports). HP Network
Advisor Professional supports the DC04 SAN Director, the SN8000B 4-Slot SAN Director
Switch and the 4/256 SAN Director (but not DC SAN Backbone Director or the SN8000B
8-Slot SAN Backbone Director Switch), FC switches, FCIP switches, FCR switches/Integrated
Routing (IR) capabilities, FCoE/CEE switches, and Brocade HBAs.
• HP Network Advisor Professional Plus—A SAN management application designed for medium
size businesses to manage up to four physical Fabric OS fabrics and up to 2,560 switch ports.
HP Network Advisor Professional Plus supports the DC04 SAN Director, the SN8000B 4-Slot
SAN Director Switch and the 4/256 SAN Director (but not DC SAN Backbone Director or
SN8000B 8-Slot SAN Backbone Director Switch), FC switches, FCIP switches, FCR
switches/Integrated Routing (IR) capabilities, FCoE/CEE switches, encryption switch and
