HP 4400 HP StorageWorks Fabric OS 6.4.0c Release Notes (5697-0703, September 2 - Page 29

• The Fabric Provided MAC Address (FPMA) and Fibre Channel Identifier (FCID) assigned to a VN_Port cannot be associated with any 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 Organizationally Unique Identifiers (OUI) of 00051E or 000533 (phased in beginning in April 2010) are being used by Brocade while assigning the WWNs to 2408 FCoE Converged Network Switches, DC SAN Backbone Directors, and DC04 SAN Directors, which would make only the last three bytes different for any two 2408 FCoE Converged Network Switches, DC SAN Backbone Directors, or DC04 SAN Directors. Considering this assignment method, the merge logic would rename the login group by including the last three bytes of the WWN in the login group name, so that they are unique in the merged configuration. • For switches having different OUI indexes from the eight assigned to Brocade (for example, 00051E and 006069), WWNs can differ in more than three bytes. In this case, after a normal merge and a rename, per the logic described above, 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 fosconfig -enable ethsw command before powering on a DC SAN Director Switch 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. • Upgrading firmware on the 2408 FCoE Converged Network Switch to Fabric OS 6.4.x, or downgrading from Fabric OS 6.4.x, disrupts the FC traffic through the switch. • For HP StorageWorks DC SAN or DC04 SAN Directors with one or more SAN Director Switch 10/24 FCoE blades installed, downgrading or upgrading the Fabric OS 6.4 firmware to another version disrupts traffic through the blades. HA Failover of CP blades in either of these directors disrupts traffic through the 10/24 FCoE blades. • Connecting a 2408 FCoE Converged Network Switch to an FCR-capable switch with fcrbcast config enabled will cause a storm of broadcast traffic, resulting in termination of iswitchd. • When rebooting a DC SAN director or DC04 SAN director with DC SAN 10/24 FCoE blade, Qlogic CNA and LSAN zoning, the switch becomes unresponsive for a period of time. This is due to the CNA sending excessive MS queries to the switch. • A DC SAN 10/24 FCoE blade installed in the highest numbered slot of a DC SAN director or DC04 SAN director does not send out FIP unsolicited advertisements. Therefore, it does not support FCoE functionality when installed in this slot. • The 2408 FCoE Converged Network Switch and DC SAN 10/24 FCoE blade can handle 169 small FCoE frames in bursts. If you are using the 2408 FCoE Converged Network Switch or DC SAN 10/24 FCoE blade, and you delete a large number of v-ports with HCM, some of the v-ports may not appear to be deleted. To correct this, disable and re-enable FCoE with the following CLI commands: switch:admin>fcoe --disable switch:admin>fcoe --enable Virtual Fabrics • On VF-capable platforms, the VF feature (initially supported with Fabric OS 6.2.0a) must be enabled in order to utilize the related capabilities, including logical switches and logical fabrics.
