HP StorageWorks HA-Fabric Manager Release Notes, V08.08.00 (AA-RUR6H-TE, December 2005)

• If Switch Binding is activated using the Element Manager with an F-Port logged
in to the McDATA 4G b SAN Switch tha t is not in the Switch Binding membership
list (for example, an administrator command has not logged out the unwanted
port), Fabric Binding cannot be activated using HAFM.
Minor code enhancements and fixes in M-Series firmware 08.01.00
The release of fir
mware 08.01.00 incorporates some m inor code enhancements and
fixes, and is not a mandatory upgrade, though HP recommends that all Directors and
Edge Switches be upgraded to this version of firmw are.
McDATA 4Gb SAN Switch Element Manager support
Provides support for launching the McDATA 4Gb SAN Switch Element Manager through
HAFM. Firmware 5.2.2.15.00 is the minimum version of firmware required for HAFM
Element Manager support.
Advanced Fab
ric Diagnostics enhancements
The followin
g enhancements have been made to Advanced Fabric Diagnostics features
(requires fir
mware 08.01.00 or later; not supp orted by McDATA 4Gb SAN Switch):
• 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 a nd Edge Switches. Users
can configure policies to detect ports that are violating security rules, as well as
link-lev
el problems, s uch 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 ma nually to a llow the ISL or
node to re
cover 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 o perations
adversely. Port Fencing can detect many of these conditions and prevent adverse
conseq
uences.
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 p olicies provide a
reasonable level of protection, but further refinement may be necessary to
accom
modate specificSANbehavior.
During planned maintenance or ser vice operations, HP recommends disabling
appropriate policies to p revent fencing of por ts from expected behavior.
New CLI commands support this enhancement.
• Embe
dded Port Log—CLI Enhancements enable users to specify trigger p oints
that
will star t a nd stop events from being written to the Embedded Port Log.
The
se triggers consist of a data p at tern and offset into the Fibre Channel frame.
