HP B-series Fabric OS 7.1.1a Release Notes (5697-3023, November 2013 - includes all 7.1.1x versions)

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 StorageWorks SAN Director 48-port 8 Gb FC Blade and HP StorageWorks 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 StorageWorks 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 StorageWorks DC SAN Backbone
Director Switch.
• Loop devices continue to be supported with no new restrictions, when attached to ports on
the HP StorageWorks SAN Director 16-port 8 Gb FC Blade and the HP StorageWorks SAN
Director 32-port 8 Gb FC Blade.
ICLs on HP StorageWorks DC SAN Backbone Director Switch /HP StorageWorks DC04 SAN
Director Switch
• If an HP StorageWorks DC SAN Backbone Director Switch with an 8-link ICL license is
connected to an HP StorageWorks DC SAN Backbone Director Switch with a 16-link license,
the HP StorageWorks 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 StorageWorks DC SAN Backbone Director Switch with a 16-link license is
connected to an HP StorageWorks 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
advised to check the speed setting of the neighboring switch port to determine the cause of the
speed negotiation failure.
Example output:
74 9 10 36ed40 id N8 In_Sync FC Disabled (Port Throttled)
