• 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 7.0.0a or downgrading from v7.0.0a 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. • Connecting HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE 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 and LSAN zoning, the switch becomes very unresponsive for a period of time. This is due to the CNA sending excessive MS queries to the switch. • The HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE Switch and HP DC SAN Director 10/24 FCOE Blade can handle 169 small FCoE frames in bursts. If you are using the HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE Switch or HP DC SAN Director 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 slot/port • switch:admin>fcoe --enable slot/port • When an HP DC SAN Director 10/24 FCOE Blade is powered off during configuration replay, the interface specific configuration does not get applied. Later when the HP DC SAN Director 10/24 FCOE Blade is powered on, all physical interfaces come up with default configurations. The user can execute the copy startup-config running-config command to apply the new configuration after powering on the HP DC SAN Director 10/24 FCOE Blade. • When IGMP Snooping is disabled on a VLAN, all configured IGMP groups are removed from that VLAN. You must reconfigure the IGMP groups after enabling the IGMP snooping on that VLAN. IMPORTANT: When upgrading from Fabric OS 6.3.x or 6.4.x to 7.0.0a or later, the CEE start up configuration dcf.conf file is incompatible with the FCoE provisioning changes implemented in 7.0.0a and later releases. Users can save the dcf.conf file as a backup and apply it once the firmware upgrade is completed to get the DCX/DCX-4S to the same startup configuration as in the older release.

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

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 7.0.0a or downgrading from v7.0.0a is disruptive to the I/O through the switch.
•
Upgrading firmware on an HP StorageWorks DC SAN Backbone Director Switch or HP Storage-
Works 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.
•
Connecting HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE 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 and
LSAN zoning, the switch becomes very unresponsive for a period of time. This is due to the CNA
sending excessive MS queries to the switch.
