New feature descriptions
This section describes the new features that were introduced in Fabric OS 6.2.0a.
Virtual fabrics
•Virtual Fabrics (VF) is a new capability supported on the HP StorageWorks DC SAN Backbone
Director, DC04 SAN Director, HP StorageWorks 8/80 SAN Switch, and HP StorageWorks 8/40
SAN Switch. Once enabled, VF allows the user to divide a single physical chassis or switch into
multiple logical switches by assigning individual ports to a logical switch. Each of these logical
switches is managed as a completely independent layer 2 Fibre Channel switch, and can be de-
ployed in independent fabrics known as logical fabrics.
•VF also allows the user to create a special logical switch known as the base switch, used for
connectivity to other base switches and also as a backbone fabric for Fibre Channel Routing. In-
dividual logical fabrics may utilize this shared base fabric for connectivity to other switches,
4

providing efficient use of resources by sharing common ISL and ICL connections among multiple
logical fabrics.
•The Virtual Fabrics feature is part of the base Fabric OS and does not require a license. Virtual
Fabrics is fully compatible with legacy Brocade products as well as M-Series switches and directors.
FCR and FCIP enhancements
•FCIP (SCSI) Read Tape Pipelining anticipates host read operations and buffers data to reduce
latency from the FCIP WAN.
•LSAN Tagging provides special behavior for designated LSAN zones using either a new speed
tag or enforce tag. The enforce tag allows individual FCRs to be configured only to import devices
in specific LSAN zones, increasing scalability. The speed tag allows designated targets to remain
imported, allowing sensitive hosts to discover targets much faster. This is useful when performing
boot over LSAN operations
•SoTCP Enhancements improve network congestion management in Slow Start Mode and helps
prevent host I/O timeouts.
•Support for Pathinfo over MetaSAN. The Pathinfo command has been enhanced to provide
path information across routed fabrics, which is especially useful when troubleshooting connectivity
problems across routed fabrics.
•FSPF cost in FCR backbone fabric uses the most efficient route to reach a destination fabric, pre-
venting the use of an FCIP link when an ISL is available.
•In-band management link over FCIP connections for the HP StorageWorks 400 Multi-protocol
Router allows a management station to communicate with a remote 400 Multi-protocol Router
through the GE ports. This allows a single management station located on the WAN side of the
400 Multi-protocol Router to communicate with the management interface on the CP for management
tasks such as firmware downloads, snmp polling, snmp traps, trouble shooting, and configuration.
Enhanced Native Connectivity with McDATA products
•Fabric OS 6.2 and M-EOS 9.9 now support Frame Redirection in McDATA Open Fabric Mode
(interopmode 3) fabrics. Frame Redirection zones must be created and activated from Fabric OS
platforms.
•Fabric OS platforms now support EX_Port connections to McDATA Open Fabric Mode Mi10ks
using the 239 DID setting.
Security enhancements
•Configurable stateless IPv6 auto-configuration support.
•IPSec with IPv6 support provides greater security for management ports and configurable security
policies for IPv4/6 addresses.
•A switch-wide policy requiring HBA authentication requires the FC-SP bit to be set in FLOGI. If the
bit is not set, the FLOGI is rejected and the port is disabled.
•A new warning for RADIUS login allows users to configure how many days in advance they should
be notified of password expiration.
•An LDAP enhancement adds the ability to provide an alternate UPN (userPrincipalName) to domain
authentication.
Contact your switch vendor regarding the use of other backup applications.
Optionally licensed software
The following are optionally licensed features in Fabric OS 6.2:
•Ports on Demand allows customers to instantly scale the fabric by provisioning additional ports
via license key upgrade (applies to select models of switches).
HP StorageWorks Fabric OS 6.2.0b release notes 5

•Extended Fabrics provides greater than 10 km of switched fabric connectivity at full bandwidth
over long distances (depending on platform, the distance can be up to 3000 km).
•ISL Trunking provides the ability to aggregate multiple physical links into one logical link for en-
hanced network performance and fault tolerance. This also includes Access Gateway ISL Trunking
on those products that support Access Gateway deployment.
•Advanced Performance Monitoring enables performance monitoring of networked storage resources.
This license includes the TopTalkers feature.
•High Performance Extension over FCIP/FC (formerly known as FC-IP Services) for the HP Storage-
Works B-Series Multi-protocol Router blade and 400 Multi-protocol Router). This license key also
includes the FC-Fastwrite feature and IPsec capabilities.
•Accelerator for FICON license enables unique FICON emulation support for IBM’s Global Mirror
(formerly XRC) application (including Hitachi Data Systems HXRC and EMC’s XRC) as well as
Tape Pipelining for all FICON tape and virtual tape systems to significantly improve XRC and tape
backup/recovery performance over virtually unlimited distance for HP StorageWorks 400 Multi-
protocol Router and B-Series Multi-protocol Router blade.
•Fabric Watch monitors mission-critical switch operations. Fabric Watch now includes new Port
Fencing capabilities.
•The FICON Management Server (also known as CUP or Control Unit Port) enables host-control of
switches in Mainframe environments.
•ICLs, or Inter Chassis Links, provide dedicated high-bandwidth links between two HP StorageWorks
DC SAN Backbone Directors or DC04 SAN Director switch chassis, without consuming valuable
front-end 8G ports. Each DC Backbone Director/DC04 SAN Director must have the ICL license
installed in order to enable the ICL connections. (Available on the DC Backbone Director/DC04
SAN Director only)
•Adaptive Networking provides a rich framework of capability allowing a user to ensure high pri-
ority connections and obtain the network resources necessary for optimum performance, even in
congested environments. The QoS SID/DID Prioritization and Ingress Rate Limiting features are
the first components of this license, and are fully available on all 8G platforms.
•The Integrated Routing license allows ports in an HP StorageWorks DC SAN Backbone Director,
HP StorageWorks DC04 SAN Director, HP StorageWorks 8/80 SAN Switch, or HP StorageWorks
8/40 SAN Switch, to be configured as EX_ports supporting Fibre Channel Routing. This eliminates
the need to add an B-Series Multi-protocol Router blade or use the 400 Multi-protocol Router for
FCR purposes, and also provides double the bandwidth for each FCR connection (when connected
to another 8G-capable port).
•A Server Application Optimization license, introduced with Fabric OS 6.2, when deployed with
Server Adapters, optimizes overall application performance for physical servers and virtual machines
by extending virtual channels to the server infrastructure. Application specific traffic flows can be
configured, prioritized, and optimized throughout the entire data center infrastructure.
Included licensed software
The Enhanced Group Management license is included with all HP 8Gb switches. Enhanced Group
Management enables full management of the device in a datacenter fabric with deeper element
management functionality and greater management task aggregation throughout the environment.
This license is used in conjunction with Data Center Fabric Manager (DCFM) application software.
Temporary license support
Temporary licenses are not currently supported by HP.

IMPORTANT:
Although the HP StorageWorks 4/8 SAN Switch uses the same hardware as the 4/16 SAN Switch,
it does not support Access Gateway. The same applies to the HP StorageWorks 8/8 and 8/24 SAN
Switches. Both use the same hardware, but only the 8/24, which has all ports licensed, has Access
Gateway support. Also, Access Gateway mode is not supported with the Brocade 4-Gb SAN Switch
for HP p-Class BladeSystem (Brocade 4012) if any half-height BladeServers (BL3xp) are configured
in the same sleeve in the p-Class enclosure. For the latest updates, see the HP website:
http://www.hp.com
Access Gateway connectivity is supported by the switches listed in Access Gateway support and also
by the following B-Series switches:
•HP StorageWorks EVA4400 embedded switch module
•HP StorageWorks 8/40 SAN Switch
•HP StorageWorks 8/80 SAN Switch
•HP StorageWorks DC SAN Backbone Director
•HP StorageWorks 4/256 SAN Director
•HP StorageWorks SAN Switch 4/32
•HP StorageWorks SAN Switch 4/32B
•HP StorageWorks SAN Switch 4/64
•HP StorageWorks 400 Multi-Protocol Router
Access Gateway was introduced with Fabric OS 5.2.1b. It allows a switch to operate in agmode ,
which allows simplified connectivity between large numbers of servers and the SAN. Access Gateway
leverages N_Port ID Virtualization (NPIV) to hide the complexity of the servers (both physical and
virtual) attached to it, while allowing easy SAN connectivity. The edge fabric switch provides all fabric
services, while Access Gateway connects to the edge switch by what appears as a host bus adapter
(HBA) connection. This architecture allows the deployment of many additional servers without requiring
a domain and the associated fabric rebuild traffic. Rebuild traffic is prevalent when switches are
powered on, added, or removed from a fabric.
See the Brocade Access Gateway Administrator's Guide, available on http://www.hp.com/go/san
for more information.
Access Gateway support in non-Brocade fabrics
In addition to being supported in Brocade fabrics, Access Gateway is supported for connectivity to
the following:
•McDATA fabrics running EOS 09.00.xx with Brocade Fabric OS 5.2.1b
•McDATA fabrics running EOS 09.02.xx or 09.03.xx with Brocade Fabric OS 5.3.0, 5.3.0a,
5.3.0b, 5.3.0c, 5.3.0d
•McDATA fabrics running EOS 09.06.x with Brocade Fabric OS 5.3.1, 5.3.1a, 6.0.0b, 6.0.1a

•Cisco fabrics running SAN-OS versions 3.0(2a) with Brocade Fabric OS 5.3.1, 5.3.1a, 6.0.0b,
6.0.1a
HP StorageWorks Fabric OS 6.2.0b release notes 11

Secure Fabric OS feature not compatible with Fabric OS 6.x
and later
Fabric OS 5.3.x is the last Fabric OS version which was compatible with SFOS. However, all of the
security features of SFOS have been fully integrated into the base Fabric OS, starting with Fabric OS
5.3.x.
Zoning and fabric operations
When configuring zoning or other fabric-wide settings in a fabric that has products operating with
different versions of Fabric OS, HP recommends that you perform the configuration via an interface
(such as Web Tools) to a product with the most recent version of Fabric OS. Some older versions of
Fabric OS do not fully support newer hardware models, and problems may arise when configuring
settings through these older products.
NOTE:
Never perform a zoning configuration through a switch operating with Fabric OS 3.x in a fabric that
also has products operating with newer versions of Fabric OS.
Prerequisites
Table 1 lists the supported Fabric OS firmware versions. HP recommends using the latest supported
firmware release versions to get the greatest benefit from the SAN.
For a list of retired products, see the HP website:
http://www.hp.com
IMPORTANT:
The Fabric OS versions listed in the Earliest compatible version column in Table 1 are the earliest
versions supported by HP at the time of the Fabric OS 6.2.0b release.

HP StorageWorks Fabric OS 6.2.0b release notes 15

Important notes
This section contains information that you should consider before you use this Fabric OS release.
DCFM compatibility
Fabric OS 6.2 is fully compatible with HP StorageWorks Data Center Fabric Manager (DCFM) 10.1.x
management software. DCFM is a comprehensive SAN management application that enables
end-to-end management of HP B-Series Data Center Fabrics. It is the next-generation product and the
successor to existing B-Series management products, including HP StorageWorks Fabric Manager
(FM) and Enterprise Fabric Connectivity Manager (EFCM).
DCFM is available in two versions: DCFM Professional, an application bundled with B-Series switches
that is ideally suited for small and medium size businesses that need a light weight management
product to manage their smaller fabrics (one physical fabric at a time, up to 1,000 ports); and DCFM
Enterprise, that is designed for enterprise-class customers and showcases unparalleled performance
and scalability (24 physical fabrics, up to 9,000 switch ports). DCFM Enterprise configures and
manages HP StorageWorks DC SAN Backbone Directors, along with other B-Series directors, routers,
and switches. and HBAs. Existing EFCM and FM customers that have active Maintenance and Support
contracts are provided a seamless migration path to DCFM Enterprise.
Fabric OS compatibility
Table 1 on page 12 lists the earliest versions of software supported in this release, that is, the earliest
supported software versions that interoperate. Brocade recommends using the latest software versions
to get the greatest benefit from the SAN.
When using the new Virtual Fabrics feature, it is HP recommends that all switches participating in a
fabric with a logical switch use the latest firmware available for those switches. All switches must be
operating at minimum firmware levels noted in the Fabric OS Interoperability table.

Fabric OS feature compatibility in native connectivity modes
Some Fabric OS features are not fully supported when operating in the native connectivity modes for
deployment with M-EOS-based products. All HP StorageWorks models that are supported by Fabric
OS 6.2.0b support both interopmodes 2 and 3, with the exception of the HP StorageWorks 4/32
SAN Switch.
NOTE:
HP may not support all of these switches in this mode. See “Merging Fabrics based on M-Series and
B-Series FC switches”application note available at http://www.hp.com for specific support in
interopmodes 2 and 3.
Table 5 specifies the support of various Fabric OS features when operating in either interopmode 2
(McDATA Fabric Mode) or interopmode 3 (Open Fabric Mode) with Fabric OS 6.2.0b.

1Only Frame Reduction zones can be configured on Fabric OS platforms and sent to fabrics operating in McDATA Open
Fabric Mode (interopmode 3). M-EOS 9.9 is required to support FR zones in McDATA Open Fabric Mode.
2Requires M-EOS 9.7 or later for redirection between devices attached to Fabric OS switches, M-EOS 9.8 for redirection
between devices attached to M-EOS switches, M-EOS 9.9 for use in McDATA Open Fabric Mode. Supported EOS platforms
include M4400, M4700, M6140, and Mi10K.
3To support Frame Reduction to an edge M-EOS fabric, there must be at least one Fabric OS switch in the edge fabric to
configure Frame Redirection Zones.
4All routers (EX_Ports) must reside in a backbone fabric running in interopmode 0 only. Only edge fabrics with devices imported
to the backbone fabric or other edge fabrics can be operating in IM2 or IM3.
5This feature is available, but not officially tested or supported.
6SCC policies supported only in conjunction with 1.2 Fabric Binding support.
7Allowed only between Fabric OS-based switches.
8DPS is supported outbound from Fabric OS-based switches. M-EOS can provide reciprocal load balancing using OpenTrunking.
9Not supported in Fabric OS 6.0 or later.
10Mode 3 qualified only with M-EOS switches
11Not on FCR.
12Supported only locally within the Fabric OS switch.
13Supported via FC Routing only. All routers in the backbone must be running Fabric OS 6.2.
NOTE:
FICON Cascaded CUP is qualified only on select platforms.
Firmware upgrades and downgrades
Upgrading to Fabric OS 6.2.0b is allowed only from Fabric OS 6.1.0a or later. The policy to support
only one-level migration, which began with Fabric OS 6.0.0, provides more reliable and robust
migrations for customers. By having fewer major changes in internal databases, configurations, and
subsystems, the system is able to perform the upgrade more efficiently, taking less time and ensuring
a truly seamless and non-disruptive process for the fabric. The one-release migration policy also
reduces the large number of upgrade-downgrade permutations that must be tested, allowing for the
thorough test and verification of supported migration paths.
The HP StorageWorks DC04 SAN Director Switch may not be downgraded from Fabric OS 6.2.0a.
All downgrades from Fabric OS 6.2.0a require a restart and are disruptive to traffic. Platforms
supporting Virtual Fabrics must have the feature disabled before downgrading to a version earlier
than 6.2.0a.
To ensure non-disruptive Hot Code Load (HCL), neighbor switches should be operating with Fabric
OS 6.2.0a or later prior to loading Fabric OS 6.2.0b on the following platforms:
•Brocade 4Gb SAN Switch for HP p-Class BladeSystem
•Brocade 4Gb SAN Switch for HP c-Class BladeSystem
•HP StorageWorks SAN Switch 4/32
•HP StorageWorks 4/8 and 4/16 SAN Switches
When upgrading to Fabric OS 6.2.0b from Fabric OS 6.1.0g or earlier, the CPs do not fully
synchronize until both the new active and new standby CPs are running Fabric OS 6.2.0b. This is
normal behavior and the firmware upgrade is still not disruptive.
HP StorageWorks Fabric OS 6.2.0b release notes 19

Fabric OS 6.2.0b does not support concurrent FC Routing (EX_Ports) and TopTalkers features Upgrading
to Fabric OS 6.2.0b requires that one of these features be disabled first.
Firmware upgrade instructions
IMPORTANT:
HP strongly recommends that users upgrade to Fabric OS 6.2.0b as soon as possible. Upgrading to
Fabric OS 6.2.0b is allowed only from Fabric OS 6.1.x. See “Update recommendations”on page
8 for additional guidelines.
NOTE:
With the introduction of Fabric OS 6.1.1, certain features and functions were removed from Web
Tools (resident in the firmware) and migrated to the Data Center Fabric Manager (DCFM) management
application. This has been carried forward to Fabric OS 6.2.x. HP recommends that before upgrading
to Fabric OS 6.2.x or later, if you are not running DCFM on your fabric, you review the “Web Tools
functionality Moved to DCFM”on page 25 and note what has changed in order to assess the impact
to your fabric.
