HP B-series Fabric OS 7.0.2d Release Notes (5697-2822, August 2013--includes all 7.0.x versions)

recommends that users perform sfpshow immediately after inserting the SFP and ensure 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/DCB/CEE (HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE Switch and HP DC SAN Director
10/24 FCoE Blade)
• When upgrading an HP 2408 24-10 GbE with 8-8 Gbps FC Base FCoE switch or an HP
StorageWorks DC SAN Backbone Director Switch/HP StorageWorks 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 7.0.0a 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
24-10 GbE w/8-8 Gbps FC Base FCoE 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 24-10 GbE w/8-8 Gbps FC Base FCoE Switch in the path of TI
(Traffic Isolation) and ETI (Enhanced Traffic Isolation) Zones is not prohibited, it is not supported.
Configuring HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE Switch in the TI/ETI Zone path
is not recommended and 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 24-10 GbE w/8-8 Gbps FC Base FCoE Switch balances the FCoE bandwidth
across all six port groups (each port group contains four ports). To get 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 StorageWorks
DC SAN Backbone Director Switch or HP StorageWorks DC04 SAN Director Switch with an
