FICON support
The HP StorageWorks DC04 SAN Director is not supported for FICON Cascading in interopmode
2 or 3 for use in mixed fabrics with M-EOS platforms.
NOTE:
For information about specific versions of Fabric OS support for FICON, see the B-series FICON
Connectivity Stream.
Other important notes and recommendations
This section contains additional information that you should consider before you use this Fabric OS
release.
Virtual Fabrics
•
On VF-capable platforms, the VF feature must be enabled after upgrading to Fabric OS 6.2.x in
order to utilize the related capabilities, including Logical Switches and Logical Fabrics.
•
When creating Logical Fabrics that include switches that are not VF-capable, it is possible to have
two Logical Switches with different FIDs in the same fabric. Be sure to verify that the FIDs match
for all switches in the same Logical Fabric.
•
The aptpolicy can be configured per logical switch. The Administrator Guide indicates it is a
chassis-level setting.
•
In order to support non-disruptive Hot Code Load on an HP StorageWorks 8/40 SAN Switch with
VF enabled, the total zoning DB size for the entire chassis should not exceed 1 MB.
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.
