HP StorageWorks Fabric OS 6.1.0h release notes 3

New feature summaries
This section lists features and improvements implemented with Fabric OS 6.1.0a. Fabric OS 6.1.0h
continues this support.
Enhanced connectivity with McDATA products
McDATA connectivity enhancements include:
•M-EOS Native Fabric Mode support—HP supports Interop Mode 2 on Fabric OS 6.1.x on the
4/256 SAN Director & DC SAN Director. This allows Directors to participate directly in M-EOS
fabrics running in McDATA Fabric Mode. M-EOS products in the fabric must be running M-EOS
09.07.02 or later.
•M-EOS Open Fabric Mode support—HP supports Interop Mode 3 on Fabric OS 6.1.x with the
4/256 SAN Director & DC SAN Director. This allows Directors to participate directly in M-EOS
fabrics running in Open Fabric Mode. M-EOS products in the fabric must be running M-EOS
09.07.02 or later. Interop Mode 3 scalability limits have also been increased to match those of
Interop Mode 2.
•Traffic Isolation Zones supported in mixed fabrics in Interop Mode 2—Fabric OS 6.1.x allows the
Traffic Isolation Zones capability to be used in fabrics with M-Type products. The M-EOS based
products can also provide analogous capability through the use of Preferred Path configurations.
•Frame Redirection—Fabric OS 6.1.x allows Frame Redirection to be used on FOS products that
are operating in either of the native connectivity modes (Interop Mode 2 or 3). This provides even
greater flexibility and support for environments that are interested in using the powerful Frame
Redirection capability.
Access Gateway
Access Gateway enhancements include:
•Trunking with Access Gateway—Enables frame distribution across a set of available paths linking
Access Gateway to an adjacent switch. The adjacent switch to the Access Gateway has to be an
HP StorageWorks switch running Fabric OS 6.1.x or later. This feature also enhances availability
by enabling seamless fail-over of traffic from a failed N_Port to other ports within a trunk group.
Trunking is an optionally licensed feature.
•Advanced Device Security Policy (ADS)—Extends the DCC policy to a switch module in Access
Gateway mode. DCC policy support enables a user to restrict N_Port logins through an F_Port of
an Access Gateway. The user must provide a list of device Port WWNs for an F_Port in order to
enable those devices to login through that F_Port. This policy is also supported for NPIV connections
on F_Ports.
•16-bit routing enhances interoperability of Access Gateway with Cisco fabrics. This capability
only applies to 8-Gb platforms.
Integrated Routing
This new licensed capability allows ports in a DC Director, 8/40 SAN Switch, or 8/80 SAN Switch
to be configured as EX_Ports supporting Fibre Channel Routing. This eliminates the need to add an
MP Router blade (FR4-18i) or use the 400 MP Router for FCR purposes. Integrated Routing provides
double the bandwidth for each FCR connection (when connected to another 8-Gb-capable port).
4

Traffic Isolation Zones over FCR
This enhancement enables traffic isolation across EX ports and VEX ports. This benefits applications
like Tape Pipelining and Fast Write that traverse VE ports where customers want to control the exact
path and ports that are used.
Port Mirroring
Fabric OS 6.1.x adds support for Port Mirroring to 8-Gb ports. The Port Mirroring feature mirrors
traffic in both directions between a source and destination ID pair to a single mirror port. The user
may connect an FC analyzer to this mirror port to capture all the mirrored traffic and perform
troubleshooting or other analysis.
Buffer credit recovery
Fabric OS 6.1.x implements credit recovery protocol as described in FC-FS standards. This feature is
supported only on E_Ports and allows switches to automatically recover buffer credits that were
accidentally “lost” over time. Buffer credit recovery prevents link performance degradation that can
otherwise occur due to loss of credits over time.
FCIP performance enhancements
Fabric OS 6.1.x increases committed rate tunnel performance (utilization) when compressibility exceeds
2:1. Previous firmware releases capped FC data rates to two times the committed rate of the FCIP
tunnel. As a result, as compression ratio increases beyond 2:1, FC throughput remains constant at
two times the committed rate, and the link utilization decreases. Fabric OS 6.1.x now monitors
compressibility, adjusts to more compressible data, and works to fill the FCIP tunnel to the committed
rate.
In addition, the portcfg fciptunnel command has been modified to include a ‘–bstr’ option.
When creating a tunnel, adding this option to the end of the command string enables the byte streaming
feature on that tunnel.
To enable the byte streaming option:
portcfg fciptunnel ge0 create 0 90000 –f –bstr
To disable the byte streaming option:
portcfg fciptunnel ge0 modify 0 –bstr 1
NOTE:
The Help command has also been updated to include the following line -bstr, which turns on TCP
byte streaming.
Port Fencing
Fabric OS 6.1.x includes new Port Fencing capabilities that can automatically isolate a port that is
behaving outside the bounds of a normal, expected operation. This enhances overall stability of the
fabric in the event of an isolated event that could otherwise cause a major disruption if left unattended.
The Port Fencing capability is included as part of the optionally licensed Fabric Watch feature.
HP StorageWorks Fabric OS 6.1.0h release notes 5

LDAP
FOS 6.1 includes enhancements to LDAP allowing Active Directory server roles to be mapped to the
various switch roles.
Parameter added for slotshow command
An optional –m parameter has been added for the slotshow command, to display Model Names
for each blade installed in a DC SAN Director or 4/256 SAN Director chassis.
Scripting
Many automatic page breaks in CLI output for commands have been removed to better facilitate
scripting.
Notification of duplicate WWN entry
A RASLOG entry will occur when a switch detects a duplicate WWN has logged in.
Update recommendations
All products supported by Fabric OS 6.0.x can be upgraded to Fabric OS 6.1.0h. If applicable, HP
recommends that users upgrade to Fabric OS 6.1.0h as soon as possible in order to take advantage
of the latest fixes and features.
Upgrading to Fabric OS 6.1.0h is allowed only from Fabric OS 6.0.0b and later. This 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-destructive process for the fabric. The new one-release migration
policy also reduces the large number of upgrade/downgrade permutations that must be tested.
Only products based on 4-Gb and 8-Gb-capable ASICs are supported by Fabric OS 6.1.0h. Older
products that use 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 6.1, as well as for routing.
For information on how to access the latest Fabric OS 6.1.0h firmware, see Firmware upgrade
instructions, page 13.

Access Gateway support
Access Gateway mode is supported on the following HP products only:
•Brocade 4-Gb SAN Switch for HP p-Class BladeSystem (Brocade 4012)
•Brocade 4-Gb SAN Switch for HP c-Class BladeSystem (Brocade 4024)
•HP StorageWorks 4/16 SAN Switch (Brocade 200E)
•HP StorageWorks 8/24 SAN Switch (Brocade 300)
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. 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 within the p-Class enclosure.
Access Gateway connectivity is supported by the above referenced switches 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 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 initially introduced with Fabric OS 5.2.1b. It allows a switch to operate in a
special agmode to simplify 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
the 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 that is prevalent when switches
are powered on, or added, or removed from a fabric.
See the Brocade Access Gateway Administrator's Guide available on the HP website: 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

Secure Fabric OS (SFOS) feature not compatible with Fabric
OS 6.x and later
The last Fabric OS version compatible with SFOS is Fabric OS 5.3.x. However, all of the security
features of SFOS have been fully integrated into the base Fabric OS, beginning with Fabric OS 5.3.x
and later.
Fabric Manager compatibility
Fabric OS 6.1.0h is compatible with Fabric Manager version 5.5.0. HP recommends upgrading to
Fabric Manager 5.5.0 before upgrading to Fabric OS 6.1.0h as down-level Fabric Manager software

DescriptionTopic
•All switches and Fibre Channel Routers both in edge and backbone fabrics
must be running Fabric OS 6.1.0 in order to support this feature.
•It is essential to have “fail-over” policy enabled in all edge fabrics that are part
of the Traffic Isolation Zones, in order for the proper functioning of Traffic
Isolation over FCR.

•Port Fencing is only supported on E_Port and F_Port classes. Port Fencing is
available with the optional Fabric Watch license.
•When the port fencing feature is enabled for ITW or CRC errors, the first set
of errors detected on an active link that meet the custom high threshold level
set by the user (or the default threshold level) is always ignored to account for
expected link transition errors. The port is disabled only upon detection of a
second set of errors, that is, the next time the user-set threshold level (or default
threshold level) is reached. This prevents a port from being disabled due to
normal link transition behaviors.
•The default settings for Port Fencing reflect very low thresholds, which may
cause fence ports to experience errors. HP recommends increasing these
threshold values for use in production environments. Different platforms may
require different threshold settings for optimum behavior.
Port Fencing
Proper behavior of Port Mirroring functionality requires that the entire frame path
must contain either only 8-Gb ASICs or only 4-Gb ASICs. If a frame path contains
a mix of 8-Gb and 4-Gb ASICs, this functionality will not work as intended.
Port Mirroring
With the release of Fabric OS 6.1.x, the Web Tools and Zoning licenses are now
included in the base firmware. If a licenseshow command is executed, it shows
the Web Tools and Zoning licenses as Unknown license1 and Unknown
license2. This does not indicate a problem All the functionality provided by the
licenses in the past firmware releases will be present with 6.1.x.

Additional Fabric OS 6.1.x enhancements
Additional Fabric OS 6.1.x enhancements include:
•Provides new Fabric OS commands to rename an alias, a zone, and a zone configuration:
•Zone –copy—Copies the zone object to a new zone object.
•Zoneobjectrename—Renames the zone object.
•Detects a corrupted zone configuration [under /etc/fabos/zone*] and handles it gracefully
instead of rebooting. The switch also logs the error in RASLOG.
•Adds a new command that provides both the WWN (world wide name) and serial number of the
switch. Adds an –sn option to display the serial number. For example, wwn –sn returns both the
WWN and serial number data.
•Provides additional information on a faulty port in Fabric Watch to aid in troubleshooting.
•Enables use of passive FTP to download firmware.
•Enables the user to specify a quality password policy that prevents selecting passwords with con-
secutive, identical characters.
•Uses multiple NTP servers with the tsclockserver command for redundancy. For example, if
one site NTP server fails (DR scenario), there is a backup that can be reached by the switches.
16

•Logs a RASLog message when a 2.x switch joins the fabric.
•HA failover and user notification occurs on the 4/256 SAN Director when there is a failed Ethernet
chip (oscillator chip).
