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

using portCfgFec command. Failure to disable FEC on active DWDM links may result in link
failure during port bring up.
FICON
For FICON qualified releases, see “Additional considerations for FICON environments” (page 36)
for details and notes on deployment in FICON environments. (This section is included only for
releases that have completed FICON qualification).
FL_Port (Loop) Support
• FL_Port is not supported on HP SN8000B 16 Gb 32-port FC Blade, HP StoreFabric SN6500B
16Gb FC Switch, HP SN8000B 16 Gb 48-port FC Blade, the HP SN6000B 16 Gb FC Switch,
and the HP SN3000B 16 Gb FC switch.
• The HP SAN Director 48-port 8 Gb FC Blade and HP DC SAN Director 64-port 8 Gb FC
Blade support attachment of loop devices.
Virtual Fabrics must be enabled on the chassis and loop devices and may be attached only
to ports on a 48-port or 64-port blade assigned to a non-Default Logical Switch operating
with the default 10-bit addressing mode. They may not be in the default Logical Switch.
• A maximum of 144 ports may be used for connectivity to loop devices in a single logical
switch within a chassis in 10-bit dynamic area mode on HP DC04 SAN Director Switch.
• A maximum of 112 ports may be used for connectivity to loop devices in a single logical
switch within a chassis in 10-bit dynamic area mode on HP DC SAN Backbone Director
Switch.
• Loop devices continue to be supported with no new restrictions, when attached to ports on
the HP SAN Director 16-port 8 Gb FC Blade and the HP SAN Director 32-port 8 Gb FC Blade.
ICLs on HP DC SAN Backbone Director Switch /HP DC04 SAN Director Switch
• If an HP DC SAN Backbone Director Switch with an 8-link ICL license is connected to an HP
DC SAN Backbone Director Switch with a 16-link license, the HP DC SAN Backbone Director
Switch with the 16-link license reports enc_out errors. The errors are harmless, but continue
to increment. These errors are not reported if an HP DC SAN Backbone Director Switch with
a 16-link license is connected to an HP DC04 SAN Director Switch with only 8-link ICL ports.
• If ICL ports are disabled on only one side of an ICL link, the enabled side may see enc_out
errors.
Native Connectivity (M-EOS interoperability)
• A switch running Fabric OS 7.0.0 or later cannot form E_Port connectivity with any M-EOS
platform.
• A switch running Fabric OS 7.1.0 or later does not support EX port configuration in
Interopmode 2 or Interopmode 3.
• Device sharing between switches running Fabric OS 7.1.0 or later and McDATA fabrics is
allowed via Integrated Routing platforms using Fabric OS v7.0.x (or earlier) firmware.
Port Initialization
Users may observe that a port is in “Port Throttled” state when an F_Port is being initialized. This
is mostly an informational message that is shown in switchshow output indicating systematic
initialization of F_Ports.
However, a port may remain in “Port Throttled” state for an extended period of time and may
never come online if it fails to negotiate speed successfully with the neighboring port. Users are
