HP 4400 HP B-series Fabric OS 7.0.0a Release Notes (5697-0881, June 2011) - Page 36

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. FICON For FICON qualified releases, see the Appendix section "Additional Considerations for FICON Environments" for details and notes on deployment in FICON environments. (This appendix is included only for releases that have completed FICON qualification). FL_Port (Loop) Support • FL_Port is not supported on HP SN8000B 16Gb 32-port Fibre Channel Blade and the HP SN8000B 16Gb 48-port Fibre Channel Blade. • The HP StorageWorks SAN Director 48-port 8Gb FC Blade and HP StorageWorks DC SAN Director 64-port 8Gb 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 8Gb FC Blade and the HP StorageWorks SAN Director 32-port 8Gb FC Blade with no new restrictions. 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 36
