HP B-series Fabric OS 7.1.1a Release Notes (5697-3023, November 2013 - includes all 7.1.1x versions)

if the CEE map default is not configured before upgrading to Fabric OS 7.0.0a or later, the
following CEE map default is created automatically after upgrading to 7.0.0a or later:
◦ cee-map default
◦ priority-group-table 1 weight 40 pfc
◦ priority-group-table 2 weight 60
◦ priority-table 2 2 2 1 2 2 2 2
• When upgrading from Fabric OS 6.3.x or 6.4.x to Fabric OS 7.0.0 or later, note that the
CEE startup configuration dcf.conf file is incompatible with the FCoE provisioning changes
implemented in Fabric OS 7.0.0 or later. To ensure the HP StorageWorks DC SAN Backbone
Director Switches and HP StorageWorks DC04 SAN Director Switches have the same startup
configuration as in the older release, users can save the dcf.conf file as a backup and
apply it once the firmware upgrade is completed.
• HP recommends that Spanning Tree Protocol and its variants be disabled on CEE interfaces
that are connected to an FCoE device.
• The Fabric Provided MAC Address (FPMA) and the FC Identifier (FCID) assigned to a VN_Port
cannot be associated with any single front-end CEE port on which the FLOGI was received.
• LLDP neighbor information may be released before the timer expires when DCBX is enabled
on a CEE interface. This occurs only when the CEE interface state changes from active to any
other state. When the DCBX is not enabled, the neighbor information is not released until the
timer expires, regardless of the interface state.
• The FCoE Login Group Name should be unique in a fabric-wide FCoE Login Management
Configuration. The merge logic is designed to modify the Login Group Name during merge
when Login group names in participating configurations conflict with each other. The current
OUI being used by Brocade, assigns the WWNs to HP 2408 FCoE Switches, HP StorageWorks
DC SAN Backbone Director Switches and HP StorageWorks DC04 SAN Director Switches.
However, only the last three bytes are different for any two HP 2408 FCoE Switches, HP
StorageWorks DC SAN Backbone Director Switches or HP StorageWorks DC04 SAN Director
Switches. As compared to the OUI assignment method, the merge logic renames the login
group by including the last three bytes of WWN in the login group name, so that they are
unique in the merged configuration.
• Ethernet switch services must be explicitly enabled using the command fosconfig –enable
ethsw before powering on an HP DC SAN Director 10/24 FCOE Blade. Failure to do so
causes the blade to be faulted (fault 9). Users can enable ethsw after upgrading firmware
without FC traffic interruption.
• The HP 2408 FCoE Converged Network Switch does not support non-disruptive hot code
loads (HCL). Upgrading the HP 2408 24-10 GbE w/8-8 Gb FC Base FCoE Switch to Fabric
OS 7.0.1 or later or downgrading from Fabric OS 7.0.1 or later is disruptive to the I/O
through the switch.
• Upgrading firmware on an HP StorageWorks DC SAN Backbone Director Switch or HP
StorageWorks DC04 SAN Director Switch with one or more HP DC SAN Director 10/24
FCOE Blades from Fabric OS 6.3.x and 6.4.x to Fabric OS 7.0.0a or later is disruptive to
any traffic through the HP DC SAN Director 10/24 FCOE Blades.
• Connecting HP 2408 FCoE Converged Network Switch to an FCR-capable switch with
fcrbcast config enabled causes a storm of broadcast traffic resulting in termination of
iswitchd.
• When rebooting an HP StorageWorks DC SAN Backbone Director Switch or HP StorageWorks
DC04 SAN Director Switch with an HP DC SAN Director 10/24 FCOE Blade, Qlogic CNA
