product. Firmware 08.01.00 applies to the following M-Series Fabric Directors and
Edge Switches:
•HP StorageWorks Director 2/140
•HP StorageWorks Director 2/64
•HP StorageWorks Edge Switch 2/32
•HP StorageWorks Edge Switch 2/24
•HP StorageWorksEdgeSwitch2/16
•HP StorageWorks Edge Switch 2/12

The firmware is available on the following HP web site: http://h18006.www1.hp.com/
storage/saninfrastructure.html.
For more information on upgrading firmware versions, see the appropriate Director
or Edge Switch service manual.
Other documentation
In addition to these release notes, HP provides additional documentation available on the
following HP web site: http://h18006.www1.hp.com/storage/saninfrastructure.html.
Supported configurations
Operation of multiple switches in a fabric topology is subject to certain topology limits.
Consider the impact of these limits when planning the fabric.
NOTE:
For more information about planning the fabric, see the SAN high availability planning
guide.
•Fabric elements—Each fabric element is defined by a unique domain ID that
ranges between 1 and 31; therefore, the theoretical limit of interconnected
Directors in a single fabric is 31. The supported limit of interconnected switches
inasinglefabricis24.Becausethisnumberissubjecttochange,contactyour
HP-authorized service representative for the current number of interconnected
switches supported in a single fabric.
•Inhomogeneous fabric—To determine if interoperability is supported for a
product, or if restrictions apply, see the product publications or contact your
HP-authorized service representative.
2

•Number of interswitch links (ISLs)—The maximum supported number of ISLs is
75% of installed ports for the Director 2/64, and 50% of installed ports for the
Director 2/140. The maximum supported number of ISLs for Edge Switches is all
available switch ports. For redundancy, at least two ISLs should connect any two
Edge Switch or Director-class fabric elements. Because this number is subject to
change, contact your HP-authorized service representative for the current number
of ISLs supported per Director or Edge Switch.
•Hop count—The Fibre Channel theoretical limit of ISL connections traversed (hop
count) in a single path through a fabric is seven. The maximum supported hop
count in a single path through a fabric is three. Because this number is subject to
change, contact your HP-authorized service representative for the current hop
count supported by a single fabric path.
The hop count is equal to the number of ISL connections traversed in a single
path, not the total number of ISL connections between devices.
Cable requirements
NOTE:
Optical cables for Director and Edge Switch products must be ordered separately.
For cables measuring up to 500 meters (1 Gb/s) or 300 meters (2 Gb/s), use multi-mode
Fibre Channel cables. For longer cables, use single-mode Fibre Channel cables.
Multi-mode optical cables are connected to short-wave optical transceiver modules in
a switch. Single-mode optical cables are connected to long-wave optical transceiver
modules in a switch. Multi-mode cables should use 50/125 optical fibers, and
single-mode cables typically use 9/125 optical fibers for distances up to 10 km.
Verify that connectors interfacing with the Director or Edge Switch products use LC duplex
connectors with a PC finish. In addition, the connector at the opposite end of the cable
must be of either LC or SC type, depending on the requirements of the connected device.

product.
Minor code enhancements and fixes in firmware 08.01.00
This release of firmware 08.01.00 incorporates some minor code enhancements and
fixes,andisnotamandatoryupgrade,thoughHPrecommendsthatallDirectorsand
Edge Switches be upgraded to this version of firmware.
Advanced Fabric Diagnostics enhancements
The following enhancements have been made to Advanced Fabric Diagnostics features:
Director and Edge Switch release notes 3

•Port Fencing—Building on E_port or ISL Fencing introduced in firmware
07.xx.xx, Port Fencing policies have been enhanced to include F_ports to block
malfunctioning devices attached to M-Series Directors and Edge Switches. Users
can configure policies to detect ports that are violating security rules, as well as
link-level problems, such as a port that repeatedly exits the active-link state.
If a user-defined threshold is reached, the port is automatically blocked, and
the user is notified. Users can unblock ports manually to allow the ISL or
node to recover when the source of the problem is identified. Malfunctions in
connected hardware or Denial of Service (DoS) attacks can cause devices to
attempt repeated log-ins, which in extreme cases can impact fabric operations
adversely. Port Fencing can detect many of these conditions and prevent adverse
consequences.
Port Fencing is disabled by default. However, when enabled, default threshold
values are established for the different types of policies if the user has not
configured them manually. In most cases, the default policies provide a
reasonable level of protection, but further refinement may be necessary to
accommodate specificSANbehavior.
During planned maintenance or service operations, HP recommends disabling
appropriate policies to prevent fencing of ports from expected behavior.
New CLI commands support this enhancement. See the config.fenc-
ing.setParams command under CLI enhancements.
•Fibre Channel TraceRoute—Provides the ability to send a Fibre Channel
frame through the fabric and view its route to the destination and return to
the source. TraceRoute aids customers in troubleshooting device connectivity
problems by providing a map of routes through the fabric. See the
show.fabric.traceRoute command under CLI enhancements.
•Embedded Port Log—CLI Enhancements enable users to specify trigger points
that will start and stop events from being written to the Embedded Port Log.
These triggers consist of a data pattern and offset into the Fibre Channel frame.
CLI enhancements
The following commands and command parameters have been added to the CLI:
•config.fencing.setParams—Supported with new commands.
•config.fencing.showTypeTable—Supported with new types.
•config.switch—Commands added to the config.switch branch allow you
to enable/disable the API Interface, Web Interface, and Safe Zoning, and
commands to configure the FSPF cost of ISLs on the switch.config.switch
and the state of zoning request state change notifications (RSCNs).
•show.switch—Command added shows the IP address of the application that
is managing the switch/director and the method for computing the FSPF cost
for ISLs.
•config.snmp—Commands added to the config.snmp branch allow you
toconfigure a USM user entry in the User table, configure an entry in the
Security-to-Group table, configure v1 through v3 community strings, associate
4

and disassociate USM configuration values for trap recipients, configure entries
and set views to the Access table, and enable/disable SNMPv3.
•show.snmp—Commands that display the switch SNMP configuration,
Access table values, Target table values, users configured in the USM table,
Security-to-Group table, and values for the configured VACM views.
•show.epFrameLog.nowrap—Allows users to view the contents of the
nonwrapping portion of the Fabric Log.
•config.security.ssl—Includes commands to enable/disable SSL for the
Web Interface and API Interface.
•config.syslog—Commands added that configure and remove a syslog
server at a given index, enable/disable syslog, enable syslog support for a
specificlog,anddisplaysyslogconfiguration.
•show.port.opticHealth—Displays the overall optic health for all ports that
support enhanced digital diagnostics.
•show.port.opticData—Displays the overall optic health, enhanced digital
diagnostic data, and thresholds for a specified port.
•show.epFrameLog—Commands are available to set/disable trigger values
for the Embedded Port Frame Log and to display the current Embedded Port
Log settings.
•show.fabric.traceRoute—Shows the route between two nodes in a fabric.
HAFM Basic
The Embedded Web Server (EWS) management application has been redesigned to
ensure more consistency with the HA-Fabric Manager (HAFM) interface. Now called
HAFM Basic, this interface is manages products in a small SAN, while HAFM is
manages products in larger SANs.
HAFM Basic provides configuration support for Port Fencing policies, and enables you to
back up configuration settings to an XML file and then restore them by uploading the file.
Predictive optics monitoring
Through HAFM, HAFM Basic, and the CLI, users can monitor the health of the Fibre
Channel optics installed in Edge Switch and Director products. Optics identified as
degraded are flagged and can be replaced during a scheduled maintenance time,
preventing an unplanned outage. This diagnostic can reduce unplanned outages that
could have adverse effects on a fabric.
This feature allows manufacturer-defined limits for a digital diagnostic measurement to
be read from the installed optics and stored. Actual digital diagnostic measurements
are monitored periodically on optics and compared with the stored manufacturer
measurements to determine the overall health of the optics. When any of the digital
diagnostic measurements exceeds a threshold, an event is posted with the date/time,
port number, measurement that exceeded the threshold, and the threshold value that
was exceeded. Measurements include: temperature, voltage, current, transceiver power,
and receiver power.
Director and Edge Switch release notes 5

This feature is supported on all products except the Edge Switch 2/16 and Edge Switch
2/32. Predictive Optics Monitoring is not supported on the fiber port module (FPM) or
the firstrevisionoftheuniversalportmodule(UPM)ontheDirector2/64orDirector
2/140.
Support for this feature in the Edge Switch and Director management applications is
as follows:
•CLI—Includes a new command to display overall optic health for ports that
support enhanced digital diagnostics, and a command that displays the overall
optic health, enhanced digital diagnostic data, and thresholds for a specificport.
•HAFM—Displays events for ports that exceed threshold values.
•HAFM Basic—The Port List page includes a Health Status column that displays the
status of the installed optical transceiver (Normal, Warning, Alarm, or No Info).
Clicking the status in the column displays the health status, port type, and port
number. If the port has a digital diagnostics (DD) enabled optical transceiver,
product firmware displays reported temperature, voltage, current, transceiver
power, and receiver power. Optical transceivers also provide vendor-specific
threshold values.
Interswitch Link (ISL) cost configuration
ISL Cost Configuration gives users more control over how FSPF routing is determined for
aswitch
. Cost is a metric assigned to ISLs by the product’s Path Selection functionality to
determine the shortest path (or the path that takes the least amount of time for trafficto
travel) to a destination. A path with a lower cost is considered faster than a path with a
higher cost. Configuration is provided in HAFM Basic and CLI.
ISL Cost Configuration gives advanced users more control over their fabric configuration.
It allows them to establish all ISLs with equal cost factors, causing the switch not to
account for link speed when assigning flows to ISLs.
•CLI—The config.switch.islFSPFCost command configures the FSPF cost
of ISLs on the switch. When the islFSPFCostState command is set to ignore,
each ISL has the same FSPF cost; the actual FSPF cost is ignored. When set to
port, each ISL has a default cost, which depends on the speed of the port.
•HAFM Basic—Includes an ISL FSPF Cost Configuration field on the Switch
Parameterspagethatallowsuserstoconfigure FSPF cost of ISLs on the switch
By Port Speed or Ignore Port Speed.
•By Port Speed—When selected, the FSPF cost for each port depends on the
speed of the port. In this case, the cost is inversely proportional to the bit rate
of the ISL. The higher the bit rate, the lower the cost. The speed of the ISL is a
factor in determining the shortest path.
•Ignore Port Speed—When selected, every ISL on the switch has the same
FSPF cost. The number of hops is the primary factor in determining the
shortest path; the speed of the ISL is not considered.

Open Trunking with FMS
Open Trunking Load Balancing is now qualified in FICON environments where FICON
flows are rerouted, without encountering out-of-order frames.
Safe Zoning mode
When this mode is enabled through the CLI or HAFM Basic, zone merges are prohibited
if zone sets from different fabrics do not match, and the default zone (available in
Homogeneous Fabric mode only) cannot be activated. This prevents fabric merge
problems when zones are removed accidentally or when new unzoned devices are
added to the fabric when the default zone is enabled.
The following CLI and HAFM Basic enhancements support this mode:
•CLI—New config.switch.safeZoning command
•HAFM Basic—A Safe Zoning Mode check box on the Security menu
Security enhancements
The following enhancements have been made to Security features:
•Firmware 08.01.00 supports SSL connection for HTTP sessions managing
switches with HAFM Basic, as well as HAFM management sessions. This ensures
that all data transmitted between the switch and these management interfaces
is secure and encrypted. SSL complements the SSH support added to firmware
07.xx.xx for CLI management.
•Support for standard syslog logging functions. You can configure a central
logging service for all log events. Each log can be configured separately for
distribution to the syslog.
•The SNMP interface can be configured to operate in version 3 mode, and
support for authentication is provided. SNMPv3 provides additional security for
you to authenticate any management sessions on your M-Series Fibre Channel
switches. Consider the following:
•Theaut
hentication/privacy password (key) configured for an SNMPv3 user
on a switch is not localized. Therefore, the authentication/privacy password
configured in the SNMP management application must be a non-localized
password in ASCII format.
• Before enabling SNMPv3, ensure that all desired community strings are
configured for SNMPv3 access. If the community strings are not configured
for SNMPv3, then SNMP access will be lost.
QSA Rev 2 and RFCN support
With firmware 08.xx and later, standards-based support for the revision 2 of Query
Security Attributes (QSA) and new remote fabric change notifications (RFCNs) is
available.
Director and Edge Switch release notes 7

Previous QSA support provided a simple query facility in the switch for determining
the status of security attributes enforced on the switch. QSA Rev 2 allows a device to
register to receive RFCNs, so that it can be notified when a security change is made on
the switch or fabric. The registered device can then use QSA to query for the current
security attributes.
Performance enhancements
Firmware 08.01.00 provides significant improvements in nameserver response in
large fabric configurations. When a new zone set configuration is activated or a new
switch is added to the fabric, delays in nameserver responses are dramatically
reduced. This ensures prompt responses to nameserver queries are sent immediately
after applyingconfiguration or zoning modifications.
