HP B-series Fabric OS 7.0.2d Release Notes (5697-2822, August 2013--includes all 7.0.x versions)

FCR and Integrated Routing
• With routing and dual backbone fabrics, the backbone fabric ID must be changed to keep
the IDs unique.
• When using FC Routing in a backbone to edge configuration with an Mi10K in the edge
fabric, users may experience slow throughput for hosts attached to the Mi10K. Users may
encounter this following a bounced IFL connection between the backbone and edge fabric.
This slowdown can be resolved by disabling/enabling the Mi10K ports for the hosts that are
impacted.
• Mi10K Directors operating with firmware earlier than M-EOSn 9.9.5 may experience repeated
system faults when attached as an FCR edge switch to an HP 1606 SAN Extension Switch EX
Port. To avoid this, ensure that the Mi10K is operating with M-EOSn 9.9.5 or later when in
an edge fabric that is attached to an HP 1606 SAN Extension Switch FCR Backbone.
• VEX edge to VEX edge device sharing is not supported.
• To allow Hot Code Load on HP 8/40 Base 24-ports Enabled SAN Switch when using Integrated
Routing, the edge switch connected to the HP 8/40 Base 24-ports Enabled SAN Switch must
be running Fabric OS 6.1 or later code.
Forward Error Correction (FEC)
Although the FEC capability is generally supported on the 16 Gb capable FC ports when operating
at either 10 Gb or 16 Gb speed, it is not supported when using active DWDM links. Therefore,
FEC must be disabled on 16 Gb capable ports when using active DWDM links. Use the
portCfgFec command to disable FEC. 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
34) 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 Gbps 32-port FC Blade, HP SN8000B 16 Gbps
48-port FC Blade, the HP SN6000B 16 Gbps FC Switch, and the HP SN3000B 16 Gbps FC
switch.
• The HP StorageWorks SAN Director 48-port 8 Gbps FC Blade and HP StorageWorks DC
SAN Director 64-port 8 Gbps 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 when attached to ports on the HP StorageWorks SAN
Director 16-port 8 Gbps FC Blade and the HP StorageWorks SAN Director 32-port 8 Gbps
FC Blade with no new restrictions.
