Topic Description
HP StorageWorks
B-Series MP Router Blade
(FR4-18i)
The FR4-18i shi
ps with Fabric OS 6.x. If inserted into a chassis running a version
of firmware that is different than the revision level currently on the blade, the
blade firmware will be upgraded or downgraded to match the firmware revision
on the c hassis.
FICON support
The FC4-48 Director port blade is not supported to connect to System z
environments via FICON channels or via FCP zLinux on System z. To attach the
4/256 SAN Director to the System z environment, use an FC4-16 or FC4-32
Director blade.
Flow-Based QoS
Prioritization
• When using Quality of Servi ce (QoS) in a fabric with 4Gb ports or switches,
Fabric OS 6.x or later must be installed on all products in order to pass QoS
info.
• Any products that a re not capable of operating with Fabric OS 6.x may not
existinfabricwithFlowbasedQoS.
• If trunks are used, there should be at least two flows per priority going
through the trunk. Otherwise, bandwidth allocation might not be prioritized
proportionally.
Top Talkers
When mul
tiple F_Ports come up, the F_Port flow information displayed might not
be accur
ate. This will be resolved in a subsequent release.
Traffi cIsolation
When confi guring a TI zone with failover disabled, user needs to make sure that
the E-ports of the TI zone are corresponding to valid paths (use topologyshow
via the CLI to verify this), otherwise, routing might be missing for ports in tha t
TI zone.
Fibre Channel Router
(FCR) backbone Fabric
ID change
If there i s more than one backbone, then the backbone fabric ID must be changed
on all but one backbone in order to keep the IDs unique.
Fabric Configuration
Server (FCS) switch
Automatic Distribution

using the FCS Automatic Distribution feature in Fabric OS 6.x, all
switches in the fabric must be running a Fabric OS 6.x or later. If any switches
