Description
The FR4-18i ships with Fabric OS 6.x. If inserted in a chassis running a version
of firmware that is different than the version currently on the blade, the blade
firmware will be upgraded or downgraded to match the version on the chassis.
The FC4-48 and FC8-48 port blades are not supported to connect to System z
environments via FICON channels or via FCP zLinux on System z. To attach the
4/256 Director or DC Director to the System z environment, use an FC4-16,
FC4-32, FC8-16, or FC8-32 port blade.
When using Quality of Service (QoS) in a fabric with 4-Gb ports or switches,
Fabric OS 6.x or later must be installed on all products to pass QoS information.
E_Ports from the DC Director to other switches must come up after 6.0 is running
on those switches.
Flow-based QoS is not supported on 8-Gb blades in the 4/256 SAN Director.
Any products that are not able to operate with Fabric OS 6.x may not exist in a
fabric with flow-based QoS. Major problems occur if previous generation 2-Gb
products exist in the fabric.
With 8-Gb Director blades, the switch must be disabled to change the backbone
fabric ID.
With routing and dual backbone fabrics, the backbone fabric ID must be changed
to keep the IDs unique.
Ports 16-47 on the FC8-48 blade must not be used as EX_Ports. Only ports 0-15
should be used for FCR on the 48-port blade.
To allow hot code load on an HP 8/40 SAN Switch when using Integrated Routing,
the edge switch connected to the HP 8/40 SAN Switch must be running Fabric
OS 6.1 or later. The HP 8/40 SAN Switch does not support Hot Code Load from
Fabric OS 6.1.0 to 6.1.2b in a dual backbone configuration with a routed
connection to an M-EOS product.
When using the FCS Automatic Distribution feature in Fabric OS 6.0 or later, all
switches in the fabric must be running Fabric OS 6.0 or later. If any switches are
running Fabric OS 5.x or earlier, only manual distribution can be used.
Fabric OS 6.0 or later will only allow FCS automatic distribution when in strict
mode, requiring only switches with Fabric OS 6.0 or later.
Ports 16-47 on the FC8-48 blade must not be used for AG F_Port Trunking
connections. When in Access Gateway mode, the Automatic Port Configuration
policy may not work when attached to M-EOS switches. M-EOS ports should be
set to G_Port to prevent problems with port type discovery.
All switches and Fibre Channel routers, in both edge and backbone fabrics, must
be running Fabric OS 6.1.0a or later to support this feature.
The failover policy must be enabled in all edge fabrics that are part of the traffic
isolation zones for the proper functioning of traffic isolation over FCR.
All switches must operate with Fabric OS 6.1.x or later to support this feature.
