HP 4400 HP B-series Fabric OS 7.0.0a Release Notes (5697-0881, June 2011) - Page 34

Fabric OS 7.0.0a. After the upgrade to Fabric OS 7.0.0a, all FCoE edge ports must be provisioned with the new model before any FIP FLOGIs take place. • 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 active HP DC SAN Director 10/24 FCOE Blade results in the new standby CP not coming up. • When operating in Converged Mode, tagged traffic on the native VLAN of the switch interface is processed normally. The host should be configured not to send VLAN tagged traffic on the switch's native VLAN. • When operating in Converged Mode, tagged frames coming with a VLAN tag equal to the configured native VLAN are dropped. • The Converged Network Adapter (CNA) may lose connectivity to the HP 2408 24-10 GbE w/88 Gbps FC Base FCoE Switch/HP DC SAN Director 10/24 FCOE Blade if the CNA interface is toggled repeatedly over time. This issue is related to the CNA and rebooting the CNA restores connectivity. • The HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE Switch and HP DC SAN Director 10/24 FCOE Blade support only one CEE map on all interfaces connected to CNAs. HP does not recommend CEE map for use with non-FCoE traffic. HP recommends QoS commands for interfaces carrying non-FCoE traffic. • Before upgrading to Fabric OS 7.0.0a, if the CEE map default value already exists, the same default value is preserved after upgrading to Fabric OS 7.0.0a. However, if the CEE map default is not configured before upgrading to Fabric OS 7.0.0a, then after upgrading to v7.0.0a, the following CEE map default is created automatically: • 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 7.0.0a, the CEE start up configuration dcf.conf file is incompatible with the FCoE provisioning changes implemented in 7.0.0a. Users can save the dcf.conf file as a backup and apply it once the firmware upgrade is completed to get the HP StorageWorks DC SAN Backbone Director Switches and HP StorageWorks DC04 SAN Director Switches, to the same startup configuration as in the older release. • 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 Fibre Channel 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, irrespective 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, while assigning the WWNs to HP 2408 FCoE Switches, HP StorageWorks DC SAN Backbone Director Switches and HP StorageWorks DC04 SAN Director Switches, would make only the last three bytes as different for any two HP 2408 FCoE Switches, HP StorageWorks DC SAN Backbone Director Switches or HP StorageWorks DC04 SAN Director Switches. Considering this assignment method, the merge logic would rename 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. 34
