HP B-series Fabric OS 6.3.2e Release Notes (5697-1816, March 2012) - includes all 6.3.2x versions

Integrated routing
• To allow HCL on an 8/40 SAN Switch when using Integrated Routing, the edge switch
connected to the 8/40 SAN Switch must be running Fabric OS 6.1 or later.
• Integrated Routing and Top Talkers cannot run concurrently in Fabric OS 6.3.x. To use
Integrated Routing, be sure to disable Top Talkers before configuring EX_Ports.
FC FastWrite
When an FC FastWrite Initiator is moved to a port that does not have FC FastWrite enabled, I/O
will recover and revert to the slow path route (non-FC FastWrite). This is a change from Fabric OS
6.2.x.
Native connectivity
Fabric OS-based platforms operating in interopmode 2 or 3 should never be deployed in a fabric
without at least one M-series switch. Fabric OS switches in interopmode 3 (McDATA Open Fabric
Mode) do not support configuration of zoning without an M-series switch in the fabric. When
migrating from M-series to B-series switches, all B-series switches should be configured to
interopmode 0 (Brocade Native mode) after the last M-series switch has been removed from the
fabric.
M-EOSc switches may exhibit a behavior where they block all attached devices with a reason
indication of Blocked Temporarily, Internal. This can occur when you power cycle the
M-series switch while it was participating in a fabric with Frame Redirection zoning, a capability
used for Fabric OS-based application or encryption services. If the switch is still participating in
the fabric with Frame Redirection, issue the cfgsave command from a Brocade Fabric OS-based
switch with the Frame Redirection zone in its defined zone database. If the M-EOS switch is no
longer attached to the fabric with Frame Redirection zoning, issue the
Config.Zoning.deleteSplZoneSet command via the CLI to the M-EOS switch.
FCS Automatic Distribution
• When using the FCS Automatic Distribution feature in Fabric OS 6.0 or later, all switches in
the fabric must be running Fabric OS 6.0 or later. If any switches are running Fabric OS 5.x
or earlier, only manual distribution can be used.
• Fabric OS 6.0 or later allows FCS Automatic Distribution only when in strict mode, requiring
only switches with Fabric OS 6.0 or later.
FCAP
• Due to limitations with the certificates, FCAP authentication cannot be supported on user-defined
logical switches. FCAP will continue to function with existing certificates for non-VF and the
default logical switch of VF-enabled switches. Note that authutil is not restricted from other
logical switches at this time, so it can still be enabled on unsupported LS.
• The pkicert (1.06) utility may cause evm errors, so each new switch should be isolated from
the fabric in non-VF mode to install new certificates.
• For FIPS mode, certificates must be installed before FIPS activation.
FICON
NOTE: For information about specific versions of Fabric OS support for FICON, see the B-series
FICON Connectivity Stream.
