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

3
DPS is supported outbound from Fabric OS-based switches. M-EOS can provide reciprocal load
balancing using Open Trunking.
4
SCC policies are supported only in conjunction with L2 Fabric Binding.
5
Not supported in Fabric OS 6.0 or later.
6
Mode 3 is qualified only with M-EOS switches.
7
Not on FCR.
8
Supported only locally on the Fabric OS switch.
9
All routers (EX_Ports) must reside in a backbone fabric running in interopmode 0 only. Only edge
fabrics with devices imported to the backbone fabric or other edge fabrics can operate in
interopmode 2 or 3.
10
To support Frame Reduction to an M-EOS edge fabric, there must be at least one Fabric OS
switch in the edge fabric to configure Frame Redirection zones.
11
Only Frame Reduction zones can be configured on Fabric OS platforms and sent to fabrics
operating in McDATA Open Fabric Mode (interopmode 3). M-EOS 9.9 is required to support
Frame Reduction zones in McDATA Open Fabric Mode.
NOTE: FICON Cascaded CUP is qualified on select platforms only.
Firmware upgrades and downgrades
Upgrading to Fabric OS 6.3.2e is allowed only from Fabric OS 6.2.0a or later. The policy to
support one-level migration only, which began with Fabric OS 6.0.0, provides more reliable and
robust migrations. By having fewer major changes in internal databases, configurations, and
subsystems, the system can perform the upgrade more efficiently, ensuring a truly seamless and
nondisruptive process for the fabric. The one-release migration policy also reduces the number of
upgrade-downgrade permutations that must be tested, allowing for thorough testing and verification
of supported migration paths.
If migrating from Fabric OS 6.1.x, HP recommends that you use Fabric OS 6.2.2b or later 6.2.x
release as the migration path to 6.3.2e in order to reduce the risk of exposure to known issues at
earlier 6.2.x levels.
The 2408 FCoE Converged Network Switch does not support nondisruptive Hot Code Loads (HCLs).
As a result, any firmware upgrades are disruptive to the I/O through the switch. Similarly, a code
load of DC SAN Director or DC04 SAN Director with one or more DC SAN 10/24 FCoE blades
disrupts traffic through the blade.
When upgrading a 2408 FCoE Converged Network Switch from Fabric OS 6.1.2_cee1 to 6.3,
verify that the unit has both the FCoE and FC POD licenses installed (default for HP 2408 switches).
Units missing these licenses that are upgraded to Fabric OS 6.3 will lose functionality following a
restart or disabling of ports. When the FC POD license is installed on a unit with Fabric OS
6.1.2_cee1, the licenseShow output will indicate that the license is not applicable on
this platform. This message can be ignored and will not appear once the unit has been
upgraded to Fabric OS 6.3.
If a Fabric OS 6.2 switch is in the Federal Information Processing Standards (FIPS) mode, and has
only LDAP authentication support, and is upgraded to Fabric OS 6.3, login will fail. Therefore, if
the 6.2 switch is in the FIPS mode, you should configure both LDAP and local authentications before
upgrading it to Fabric OS 6.3. When the switch is up, you can log in to the switch and import the
certificate again. If the switch is not in the FIPS mode, you can log in to the switch with LDAP after
upgrading to Fabric OS 6.3, and then import the certificate.
Fabric OS 6.3x does not support concurrent FC Routing (EX_Ports) and Top Talkers features.
Upgrading to Fabric OS 6.3x requires that one of these features be disabled first.
If there are multiple node encryption groups (EGs) in a fabric, complete the firmware download
on one node at a time before downloading on another node.
