HP B-series Fabric OS 7.1.0c Release Notes (5697-2892, October 2013 - includes all 7.1.0x versions)

• 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 DC SAN Backbone Director Switch or HP 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 DC SAN Backbone Director Switch or HP DC04 SAN Director Switch
with an HP DC SAN Director 10/24 FCOE Blade, Qlogic CNA and LSAN zoning, the switch
is unresponsive for some time. This is due to the CNA sending excessive MS queries to the
switch.
• The HP 2408 FCoE Converged Network 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 FCoE Converged
Network 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. When the HP DC SAN
Director 10/24 FCOE Blade is powered on again, 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 startup
configuration dcf.conf file is incompatible with the FCoE provisioning changes implemented in
Fabric OS 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.
FCR and Integrated Routing
• With routing and dual backbone fabrics, the backbone fabric ID must be changed to keep
the IDs unique.
• VEX edge to VEX edge device sharing is not supported.
• To allow Hot Code Load on HP 8/40 Base SAN Switch when using Integrated Routing, the
edge switch connected to the HP 8/40 Switch must be running Fabric OS 6.1 or later code.
Forward Error Correction (FEC)
Although FEC capability is generally supported on Condor3 (16 Gb/s-capable FC) ports when
operating at either 10 Gb/s or 16 Gb/s speed, it is not supported when using active DWDM
links. Therefore, FEC must be disabled on the Condor3 ports when using active DWDM links by
