default is not configured before upgrading to Fabric OS 7.0.0c, then after upgrading to
7.0.0c, 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 7.0.0c, the CEE start up
configuration dcf.conf file is incompatible with the FCoE provisioning changes implemented
in Fabric OS 7.0.0x. 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 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, 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.
For switches having different OUI indices from the eight assigned to Brocade WWNs can
differ in more than three bytes. In this case, after normal merge and a rename according to
the described logic, login group names can be the same for WWNs differing only in OUIs.
The merge logic would drop one of the Login Groups to satisfy the requirement to keep the
Login Group Name unique in the fabric wide 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 24-10 GbE w/8-8 Gbps FC Base FCoE Switch does not support non-disruptive
hot code loads (HCL). Upgrading the HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE Switch
to Fabric OS 7.0.0c or downgrading from Fabric OS 7.0.0c 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 an v6.4.x to Fabric OS 7.0.0a or later is disruptive to
any traffic through the HP DC SAN Director 10/24 FCOE Blades.
