HP StorageWorks Fabric OS 5.3.2c release notes (5697-0150, October 2009)

CAUTION:
If the 4/256 SAN Director integrates the FC4-48 Blade or any new software features in Fabric OS
5.2.0a (such as FCR trunking) you cannot downgrade to a Fabric OS version earlier than Fabric OS
5.2.0a. If you want to do so, you must (a) remove these features, (b) physically remove the FC4–48
Blade, and then (c) downgrade the firmware.
• For any other new software features or increased scalability limits supported by Fabric OS 5.3.x,
the downgrade will be disruptive and will require a cold reboot.
• A Fabric OS 5.3.x configuration file cannot be used on the same switch after the switch has been
downgraded to firmware version 5.1.x or 5.2.x.
• When you downgrade to Fabric OS 5.0.x, you must also remove additional 5.1.x features and
any installed B-series MP Router blades.

DescriptionTopic
Starting with Fabric OS version 5.3.0, you can use the ipfilter command to
block unauthorized Telnet access. The option to disable Telnet using the configure
command is no longer available.
Use the following command to create a policy to block Telnet access to any station:
ipfilter --create blockTelnet -type ipv4 ipfilter --addrule
blockTelnet -sip any -dp 23 -proto tcp -act deny ipfilter --
activate blockTelnet
Use the following command to restore default policies for IPv4: ipfilter
--activate default_ipv4 --
See the Fabric OS 5.3.0 command reference guide for more information on the
ipfilter command.

PKI certification
With release 5.2.0 and later, the Switch Connection Control high integrity
requirement for cascading FICON is available in the standard base Fabric OS. End
users can now deploy new cascade FICON Directors without purchasing a separate
Secure Fabric OS license.
To add a new FICON Director into existing cascaded configurations already running
Secured Fabric OS, HP recommends that users continue to deploy Secure Fabric OS
on the new FICON Director instead of migrating to FOS ACL configuration.
NOTE:
The FC4-48 port Blade is not supported to connect to System z environments
via FICON channels or via FCP zLinux on System z. To attach the Director to
the System z environment, use an FC4-16 or FC4-32 Fibre Channel port Blade.
