(page 28) before you upgrade to Fabric OS 6.1.1x or later, and take note of what has changed

so you can assess the impact on your fabric.

All products supported by Fabric OS 6.0.x can be upgraded to Fabric OS 6.2.2e. If applicable,

HP recommends that you upgrade to Fabric OS 6.2.2e as soon as possible to take advantage of

the latest fixes and features.

For more information, see “Firmware upgrades and downgrades” (page 19).

Supersedes

Fabric OS 6.2.2d, released October 2010

New feature descriptions

This section describes new features introduced in Fabric OS 6.2.0a and carried forward with

Fabric OS 6.2.2e.

Virtual Fabrics

• VF is 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. When

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 logical switch is managed as

a completely independent layer 2 FC switch, and can be deployed in independent fabrics

known as logical fabrics.

• VF allows the user to create a special logical switch known as the base switch, which is used

for connectivity to other base switches and also as a backbone fabric for FCR. Individual

logical fabrics can utilize this shared base fabric for connectivity to other switches, providing

efficient use of resources by sharing common ISL and ICL connections among multiple logical

fabrics.

• VF is part of the base Fabric OS and does not require a license. VF 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 by 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 the FCR backbone fabric uses the most efficient route to reach a destination fabric,

preventing the use of an FCIP link when an ISL is available.

• In-band management link over FCIP connections for the 400 MP Router allows a management

station to communicate with a remote 400 MP Router through the GE ports. This allows a

single management station located on the WAN side of the 400 MP Router to communicate

with the management interface on the CP for management tasks such as firmware downloads,

SNMP polling, SNMP traps, troubleshooting, 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 Domain ID (DID) setting.

New feature descriptions 5

NOTE: For information on specific switches and switch firmware supported for interop applications,

see the HP StorageWorks Fabric Interoperability: Merging Fabrics Based on M-series and B-series

Fibre Channel Switches Application Notes.

Security enhancements

• Configurable stateless IPv6 auto-configuration is supported.

• IPsec with IPv6 support provides greater security for management ports and configurable

security policies for IPv4/IPv6 addresses.

• A switch-wide policy requiring HBA authentication requires that the FC-SP bit be set during

Fabric login (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 specify how many days in advance they

should be notified of password expiration.

• An LDAP enhancement adds the ability to provide an alternate UPN to domain authentication.

Port beaconing support

The portBeacon CLI command was added in Fabric OS 6.2.1. It allows individual ports to be

identified by enabling a special LED function. The portBeacon command has the following

characteristics:

• Function: Sets port beaconing mode on or off.

• Syntax: portbeacon -–mode [slot]/port

• Description: Enables or disables port beaconing mode on a specified port. This command

works with 4-Gb (or larger) FC ports, with the exception of the HP StorageWorks SAN Director

6 Port 10-Gb FC ISL Blade (FC10-6).

When beaconing mode is enabled on a port, the port LED flashes amber and green for 2.5

seconds each, in an alternating pattern, and continues until you turn it off. Beaconing mode

is useful if you want to locate a specific port.

Beaconing mode takes over the port LEDs. The normal flashing LED pattern associated with

an active, fault, or disabled port is suppressed, and only the beaconing pattern is displayed.

Other commands are still executable and functional. However, if diagnostic frame-based tests,

such as the portLoopbackTest, are executed, the diagnostic LED pattern is interleaved with the

port beaconing pattern.

• Operands: ––enable turns beaconing mode on; ––disable turns beaconing mode off.

• Examples:

To turn beaconing mode on: switch:admin> portbeacon ––enable 1/0◦

◦ To turn beaconing mode off: switch:admin> portbeacon ––disable 2/1

Diagnostics restrictions

The porttest and spinfab commands are not supported on the following ports in Fabric OS

6.2.1 or later:

• Ports connected to shared-area ports (ports 16–47 on 48-port blades)

• Ports connected to ports with area swapped

• ICLs

• Slave ports in trunk groups

• Long-distance ports

• Ports connected to a logical switch and base switch (Fabric OS 6.2.x only), if VF is enabled

Optionally licensed software

The following are optionally licensed features in Fabric OS 6.2.x:

• Ports on Demand—Allows customers to instantly scale the fabric by provisioning additional

ports via a license key upgrade (applies to select switch models).

• Extended Fabrics—Provides greater than 10 km of switched fabric connectivity at full bandwidth

over long distances. (Depending on the platform, the distance can be up to 3,000 km.)

• ISL Trunking—Provides the ability to aggregate multiple physical links into one logical link for

enhanced network performance and fault tolerance. It also includes Access Gateway ISL

Trunking on the products that support Access Gateway deployment.

• Advanced Performance Monitoring—Enables performance monitoring of networked storage

resources. This license includes the Top Talkers feature.

• High-Performance Extension over FCIP/FC (formerly known as FC-IP Services)—For the HP

StorageWorks B-series MP Router blade and 400 MP Router, this license key also includes

the FC Fast Write (FCFW) 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 the 400 MP

Router and B-series MP Router blade.

• Fabric Watch—Monitors mission-critical switch operations, and now includes new Port Fencing

capabilities.

• FICON Management Server (also known as CUP)—Enables host control of switches in mainframe

environments.

• ICLs—Provide dedicated high-bandwidth links between two DC SAN Backbone Director or

DC04 SAN Director chassis, without consuming valuable front-end 8-Gb 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—Allows a user to ensure high priority connections and obtain the

network resources necessary for optimum performance, even in congested environments. The

quality of service (QoS) SID/DID Prioritization and Ingress Rate Limiting features are the first

components of this license, and are available on all 8-Gb platforms.

• 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 FCR. This eliminates

the need to add a B-series MP Router blade or use the 400 MP Router for FCR purposes, and

also provides double the bandwidth for each FCR connection (when connected to another

8-Gb-capable port).

• 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 data center infrastructure.

Included licensed software

The Enhanced Group Management license is included with all HP 8-Gb switches. Enhanced Group

Management enables full management of the device in a data center fabric with increased element

management functionality and management task aggregation throughout the environment. This

license is used in conjunction with DCFM application software.

• HP StorageWorks 8/40 SAN Switch (Brocade 5100)

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. The 8/40 switch must also have all ports enabled

in order to support Access Gateway mode. 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”

(page 9) and also by the following B-series switches:

• HP StorageWorks SAN Switch 4/32

• HP StorageWorks SAN Switch 4/32B

• HP StorageWorks SAN Switch 4/64

• HP StorageWorks SAN Director 4/256

• HP StorageWorks SAN Switch 8/80

• HP StorageWorks DC SAN Backbone Director

• HP StorageWorks DC04 SAN Director

• HP StorageWorks 400 Multi-protocol Router

• HP StorageWorks EVA4400 Embedded Switch Module

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 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.

For more information, see the Brocade Access Gateway Administrator's Guide, available on:

http://www.hp.com/go/san

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 switches: 2/12 (ES4300), 2/24 (ES4500), 2/16 (ES3216), 2/32 (ES3232), 2/64

(ED6064), 2/140 (M6140), M4400, Mi10K running EOS 09.07.02 with Brocade Fabric

OS 6.1.0x

• McDATA switches: 2/12 (ES4300), 2/24 (ES4500), 2/16 (ES3216), 2/32 (ES3232), 2/64

(ED6064), 2/140 (M6140), M4400, Mi10K running EOS 09.09.00 or 09.09.03 with

Brocade Fabric OS 6.2.0x, 6.2.1x, and 6.2.2x

MDS 9140, MDS 9124, MDS 9134 running SAN OS 3.2(3) with Brocade Fabric OS 6.2.0x,

6.2.1x, and 6.2.2x

Secure Fabric OS feature not compatible with Fabric OS 6.x and later

Fabric OS 5.3.x is the last Fabric OS version 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.

For environments with SFOS installed on switches that cannot be upgraded to Fabric OS 5.3 or

later version, FC routing can be used to interoperate with Fabric OS 6.2.2e.

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 through 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: Do not configure zoning through a switch operating with Fabric OS 3.x in a fabric that

has products operating with newer versions of Fabric OS.

Prerequisites

Table 1 (page 11) lists the supported Fabric OS firmware versions. HP recommends using the latest

supported firmware 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 (page 11) are the earliest versions supported by HP for connection to switches running

Table notes:

In a fabric with products running older versions of Fabric OS, all zoning and fabric operations

must be performed using interfaces to products running the latest version of Fabric OS. This is

important for Brocade 3xxx series switches that do not support zoning configuration for newer

products.

Other M-EOS models can participate in a fabric with Fabric OS 6.2; however, they cannot be

attached directly to any products running Fabric OS 6.2 via an E_Port. For information about HP

support of interoperable fabrics, see HP StorageWorks Merging Fabrics Based on M-series and

B-series Fibre Channel Switches Application Notes, available at http://www.hp.com.

HP strongly recommends that M-EOS products operate with the most recent version of M-EOS

that supports interoperability. For information about HP support of interoperable fabrics, see HP

StorageWorks Merging Fabrics Based on M-series and B-series Fibre Channel Switches Application

Notes, available at http://www.hp.com.

When routing to an M-EOS edge fabric using frame redirection, the fabric must have a Fabric

OS-based product to configure the frame redirection zone information.

Products operating with Fabric OS versions earlier than 5.3.1b or 6.1.0e cannot participate in

a logical fabric that is using XISLs (in the base fabric).

SANRouters 1620 and 2640 must not be used with XPath or Fabric OS-based routing (FCR) for

connections to the same edge fabric.

These platforms cannot be attached directly to hosts or targets for encryption flows.

Using HP StorageWorks Fabric Manager (FM) 5.5 or earlier with Fabric OS 6.1.1 or later can

result in problems with Zoning, Performance monitoring, SYSLOG configuration, FICON wizards,

IOD Delay, AAA replication, Port enable/disable and other functions. Unless you are using Admin

Domains, HP recommends that you upgrade to HP StorageWorks Data Center Fabric Manager

(DCFM) 10.3.x to use with Fabric OS 6.1.1 or later. If you are using Admin Domains, HP

recommends that you upgrade to DCFM 10.4.x because it includes Admin Domain support,

although some support is limited. For more information, see the Data Center Fabric Manager User

Guide for 10.4.x.

Important notes

This section contains information that you should consider before you use this Fabric OS release.

New OUI Support on B-Series platforms

Overview

The OUI (Organizationally Unique Identifier) value is part of a Fibre Channel WWN that uniquely

identifies the manufacturer of Fibre Channel products. The OUI values assigned to Brocade are

used by Fabric OS to validate certain fabric interoperability support.

The currently assigned OUI/WWN values are nearing exhaustion, necessitating Brocade to use

a new OUI value for WWN assignment. The new OUI value for Brocade is 00:05:33. A WWN

of 10:00:00:05:33:41:5c:c1, for example, demonstrates the usage of the new OUI. WWNs

with the current OUI value are expected to be consumed by mid-2010. Brocade factory shipments

of switches after this time will have WWNs that include the new OUI.

Fabric OS 6.2.2b has been enhanced to recognize the new Brocade OUI value to guarantee

proper functionality. It is important to note that no switch with the new OUI/WWN should be

downgraded to a version of Fabric OS that does not recognize this new OUI. It is also important

to note that specific minimum requirements for recognition of the new OUI will neither be validated

nor enforced by Fabric OS.

Impact of products with the new OUI to existing fabrics/environments

In most situations, a switch that uses the new OUI can be seamlessly added to an existing fabric,

even if the other switches in that fabric are not using Fabric OS versions that are aware of the new

FC Routing scalability 15

OUI value. However, there are some exceptions and limitations to consider before adding a switch

utilizing the new OUI to an existing fabric or environment.

• Fabrics with encryption products: If an HP StorageWorks encryption switch or blade using the

new OUI is added to an edge fabric of a Fibre Channel routed fabric, Frame Redirection

capability could be impacted across the FCR backbone, thus impacting the encryption

functionality. Therefore, the FC routers in the FCR backbone fabric will need to be upgraded

to a firmware version that supports the new OUI.

• Interopmode 2 and 3 fabrics: In an interopmode 2 or 3 fabric with VE ports, the switches on

both ends of the VE link must run a firmware version that supports the new OUI, or the VE

ports may not function correctly, resulting in unpredictable behavior.

DCFM compatibility

Fabric OS 6.2.2e is fully compatible with DCFM 10.1.x, 10.3.x, and 10.4.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).

Starting with DCFM 10.3.0, DCFM is available in three versions:

• DCFM Professional—Bundled with B-series switches, it is ideally suited for small- and

medium-sized businesses that need a lightweight management product to manage their smaller

fabrics (one physical fabric at a time, up to 1,000 ports).

• DCFM Professional Plus—Designed for medium-sized businesses or departmental storage

networks, it features support for up to 4 fabrics and 2,560 ports.

• DCFM Enterprise—Designed for enterprise-class customers, it showcases unparalleled

performance and scalability (24 physical fabrics, up to 9,000 switch ports). This is the only

version of DCFM that supports the HP StorageWorks DC SAN Backbone Director and FICON.

DCFM Enterprise configures and manages DC SAN Backbone Directors, along with other

B-series directors, routers, switches, and HBAs. Existing EFCM and FM customers that have

active Maintenance and Support contracts are provided a seamless migration path to DCFM

Enterprise.

EFCM and FM compatibility

With the introduction of DCFM, both EFCM and FM have been put into sustaining mode. Significant

compatibility issues exist between FM and Fabric OS 6.1.1 and later, including (but not limited

to) compromised functionality in the zoning dialog and performance graphs, port

enabling/disabling, and FICON wizard. HP strongly recommends that customers migrate from

these products to DCFM Enterprise.

Fabric OS compatibility

(page 11) lists the earliest versions of software supported in this release, that is, the earliest supported

software versions that interoperate. HP recommends using the latest software versions to get the

greatest benefit from the SAN.

When using the new VF feature, 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 the minimum firmware levels noted in the Fabric OS Interoperability table.

When using either the HP StorageWorks Encryption SAN Switch or the HP StorageWorks DC

Switch Encryption FC Blade, switches attached to hosts and targets, or switches that are part of

the encryption flow, must operate with the following minimum levels:

• 2-Gb platforms must operate with Fabric OS 5.3.2b or later.

• 4-Gb and 8-Gb platforms must operate with Fabric OS 6.1.0h, 6.1.2a, or later.

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 supported by Fabric

OS 6.2.2e support both interopmodes 2 and 3, with the exception of the 4/32 SAN Switch.

NOTE: HP may not support all of these switches in this mode. For information about support in

interopmodes 2 and 3, see the HP StorageWorks Fabric Interoperability: Merging Fabrics Based

on M-series and B-series Fibre Channel Switches Application Notes, available at http://

www.hp.com.

Table 5 (page 17) specifies the support of Fabric OS features when operating in either interopmode

2 (McDATA Fabric Mode) or interopmode 3 (Open Fabric Mode) with Fabric OS 6.2.2e.

Allowed only between Fabric OS-based switches.

DPS is supported outbound from Fabric OS-based switches. M-EOS can provide reciprocal load

balancing using Open Trunking.

SCC policies supported only in conjunction with L2 Fabric Binding support.

Not supported in Fabric OS 6.0 or later.

Mode 3 qualified only with M-EOS switches.

Not on FCR.

Supported only locally within the Fabric OS switch.

All 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 operate in IM 2

or IM 3.

To support Frame Redirection to an edge M-EOS fabric, there must be at least one Fabric OS

switch in the edge fabric to configure Frame Redirection Zones.

Only Frame Redirection 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.

Supported through FCR only. All routers in the backbone must be running Fabric OS 6.2.x.

NOTE: FICON Cascaded CUP is qualified only on select platforms.

Firmware upgrades and downgrades

Upgrading to Fabric OS 6.2.2e 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, ensuring

a truly seamless and nondisruptive 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 DC04 SAN Director cannot be downgraded to a release earlier than Fabric OS 6.2.0a.

All downgrades from Fabric OS 6.2.x to Fabric OS 6.1.x require a restart and are disruptive to

traffic. Platforms supporting VF must have the feature disabled before downgrading to a release

earlier than 6.2.0a. When downgrading from Fabric OS 6.2.x to 6.1, configuration parameters

(such as the switch name) are not persisted in Fabric OS 6.2.

To ensure nondisruptive Hot Code Load (HCL), neighbor switches should be operating with Fabric

OS 6.2.0a or later before loading Fabric OS 6.2.2e 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 6.2.2e 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 this new version. This is

normal behavior and the firmware upgrade is not disruptive.

Fabric OS 6.2.2e does not support concurrent FC Routing (EX_Ports) and Top Talkers features.

Before upgrading to this version, you must disable one of these features.

Only products based on 4-Gb and 8-Gb-capable ASICs are supported by Fabric OS 6.2.2e. Older

products using previous generation 2-Gb ASICs will remain on the 5.x code stream. Fabric OS

5.x is fully compatible in fabrics running Fabric OS 6.2.x and for routing.

For routed SANs with M-EOS switches in an edge fabric, upgrades to Fabric OS 6.2.2e are

nondisruptive if all EX_Ports to M-EOS edge fabrics are attached to 4/256 SAN Directors with an

MP Router blade (FR4-18i).

Fabric OS feature compatibility in native connectivity modes 19

The HP StorageWorks DC SAN Director with HP StorageWorks DC Switch Encryption FC Blade

and the HP StorageWorks Encryption SAN Switch cannot be downgraded to a version earlier

than Fabric OS 6.2.0b.

After upgrading the Encryption SAN Switch and the DC SAN Director with DC Switch Encryption

FC Blade to Fabric OS 6.2.2e, you cannot downgrade them to a version earlier than Fabric OS

6.2.0d if HP SKM key vault is configured. Doing so will result in the loss of encryption services in

HP SKM environments.

If there are multiple node EGs in a fabric, complete the firmware download on one node at a time

before downloading on another node.

On the HP StorageWorks 8/8 and 8/24 SAN Switches and the Brocade 8Gb SAN Switch for

HP BladeSystem c-Class, do not use the -n option to downgrade from Fabric OS 6.2.2e to a

version earlier than 6.2.x. Using the -n option can cause the firmware versions to get out of sync,

resulting in rolling kernel panics. The switch will not recover and you will need to return it to your

supplier for repair via RMA. Switches using Integrated Routing and Fabric OS 6.2.2e cannot be

upgraded to Fabric OS 6.3.x versions earlier than 6.3.0d.

Firmware upgrade instructions

IMPORTANT: HP recommends that users upgrade to Fabric OS 6.2.2e as soon as possible.

Upgrading to Fabric OS 6.2.2e is allowed only from Fabric OS 6.1.x. For guidelines, see

(page 4).

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. If you are not running

DCFM on your fabric, HP recommends that before upgrading to Fabric OS 6.2.x or later, you

review (page 28) and note what has changed in order to assess the impact to your fabric.
