HP B-series Fabric OS 7.1.0c Release Notes (5697-2892, October 2013 - includes all 7.1.0x versions)

serial data!. Removing and re-inserting the SFP should resolve this issue. HP recommends
that users perform sfpshow immediately after inserting the SFP and make sure SFP is seated
properly before connecting the cables.
• When running Fabric OS 7.0.0a or later, if any of the following features are enabled in the
FCIP configuration, a downgrade operation to pre-Fabric OS 7.0.0a is blocked until the
features are removed from the FCIP configuration:
◦ Inband Management
◦ Multigigabit Circuit
◦ Shared GE among Logical Switches
◦ Auto-mode compression option
◦ VE as XISL
◦ 10 GigE lossless failover
◦ Modified QoS percentages
◦ 10 GigE ARL
◦ IP Configuration where multiple GigEs have same subnet values
◦ A tunnel configuration on 1GE ports that has more than 4 circuits
◦ Teradata emulation
◦ Circuits configured explicitly to be listeners or initiators
FCoE/CEE (HP 2408 FCoE Converged Network Switch and HP DC SAN Director 10/24 FCoE
Blade)
• When upgrading an HP 2408 FCoE Converged Network Switch or an HP DC SAN Backbone
Director Switch/HP DC04 SAN Director Switch with one or more HP DC SAN Director 10/24
FCoE Blades from Fabric OS 6.x to Fabric OS 7.0.0a or later, the user should carefully review
Chapter 5 of the Fabric OS 7.0.0 Converged Enhanced Ethernet Administrator’s Guide.
• Fabric OS 7.0.0 or later supports a new optimized model for provisioning FCoE with fewer
configuration steps to enable FCoE on DCB ports. These changes do not allow the HP 2408
FCoE Converged Network Switch to retain FCoE configuration information following an
upgrade to Fabric OS 7.0.0a or later. After the upgrade to Fabric OS 7.0.0a or later, all
FCoE edge ports must be provisioned with the new model before any FIP FLOGIs take place.
• Although including HP 2408 FCoE Converged Network Switch in the path of TI (Traffic Isolation)
and ETI (Enhanced Traffic Isolation) Zones is not prohibited, it is not supported. HP recommends
that the user does not configure HP 2408 FCoE Converged Switch in the Ti/ETI Zone path
because it results in undefined behavior.
• Ethernet L2 traffic with xSTP Hello timer set to less than or equal to 3 seconds may experience
momentary traffic disruption during HA failover.
• The HP 2408 FCoE Converged Network Switch balances the FCoE bandwidth across all six
port groups (each port group contains four ports). To achieve optimum performance for FCoE
traffic, HP recommends that the user distribute server CNA connections across these six port
groups.
• Hot plugging a CP with firmware level earlier than Fabric OS 6.3.0 into an HP DC SAN
Backbone Director Switch or HP DC04 SAN Director Switch with an active HP DC SAN
Director 10/24 FCOE Blade results in the new standby CP not coming up.
