Licensing behavior When operating a switch with Fabric OS 6.2.x, some licenses may be displayed as Unknown. This is due to changes in licensing requirements for some features that no longer require a license key and may still be installed on a switch. Frame Redirection In Fabric OS 6.2.x, Frame Redirection zoning is not allowed with Default Zoning (all access in IM0 and default zone in IM2). This was allowed in previous releases. There is no software enforcement to block the upgrade. Adaptive networking/flow-based QoS prioritization • When using QoS in a fabric with 4G ports or switches, Fabric OS 6.0 or later must be installed on all products in order to pass QoS info. E_Ports from the HP StorageWorks DC SAN Backbone Director or HP StorageWorks DC04 SAN Director to other switches must come up after 6.0 is running on those switches. • Flow-based QoS is not supported on FC8 blades in the HP StorageWorks 4/256 SAN Director • Any products that are not capable of operating with Fabric OS 6.0 cannot exist in a fabric with Flow-based QoS. Major problems occur if previous generation 2G products exist in the fabric. • For the HP StorageWorks SAN Switch 4/32 and SAN Switch 4/32B, if all of the ports are E_Ports and the switch is upgraded to Fabric OS 6.2.x, the buffers on the E_Ports are changed to utilize the QoS model. If the switch is rebooted, 28 of 32 ports will come up in QoS mode; the last four ports will come up in buffer-limited mode. Workarounds include disabling long distance configuration for these ports or explicitly disabling QoS on other ports, freeing up buffers for the last four ports. Fibre Channel Routing All FCR switches must be running Fabric OS 6.2.x in order to support M-EOS 239 Domain Mode on the Mi10K FCR backbone fabric ID changes • With 8Gb 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. Traffic isolation over FCR • All switches and Fibre Channel Routers, both in edge and backbone fabrics, must be running Fabric OS 6.1.0 or later in order to support this feature. • In order for Traffic Isolation over FCR to function properly, the associated TI zones in each fabric (edge and backbone) need to have failover enabled.

Licensing behavior
When operating a switch with Fabric OS 6.2.x, some licenses may be displayed as
Unknown
. This
is due to changes in licensing requirements for some features that no longer require a license key and
may still be installed on a switch.
Frame Redirection
In Fabric OS 6.2.x, Frame Redirection zoning is not allowed with Default Zoning (
all access
in
IM0 and default zone in IM2). This was allowed in previous releases. There is no software enforcement
to block the upgrade.
Adaptive networking/flow-based QoS prioritization
•
When using QoS in a fabric with 4G ports or switches, Fabric OS 6.0 or later must be installed
on all products in order to pass QoS info. E_Ports from the HP StorageWorks DC SAN Backbone
Director or HP StorageWorks DC04 SAN Director to other switches must come up after 6.0 is
running on those switches.
•
Flow-based QoS is not supported on FC8 blades in the HP StorageWorks 4/256 SAN Director
•
Any products that are not capable of operating with Fabric OS 6.0 cannot exist in a fabric with
Flow-based QoS. Major problems occur if previous generation 2G products exist in the fabric.
•
For the HP StorageWorks SAN Switch 4/32 and SAN Switch 4/32B, if all of the ports are E_Ports
and the switch is upgraded to Fabric OS 6.2.x, the buffers on the E_Ports are changed to utilize
the QoS model. If the switch is rebooted, 28 of 32 ports will come up in QoS mode; the last four
ports will come up in buffer-limited mode. Workarounds include disabling long distance configur-
ation for these ports or explicitly disabling QoS on other ports, freeing up buffers for the last four
ports.
Fibre Channel Routing
All FCR switches must be running Fabric OS 6.2.x in order to support M-EOS 239 Domain Mode on
the Mi10K
FCR backbone fabric ID changes
•
With 8Gb 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.
Traffic isolation over FCR
•
All switches and Fibre Channel Routers, both in edge and backbone fabrics, must be running
Fabric OS 6.1.0 or later in order to support this feature.
•
In order for Traffic Isolation over FCR to function properly, the associated TI zones in each fabric
(edge and backbone) need to have failover enabled.
Integrated routing
•
To allow Hot Code Load on an HP StorageWorks 8/40 SAN Switch when using Integrated
Routing, the edge switch connected to the 8/40 SAN Switch must be running Fabric OS 6.1 or
later.
