3DPS is supported outbound from Fabric OS-based switches. M-EOS can provide reciprocal load balancing using Open Trunking. 4SCC policies are supported only in conjunction with L2 Fabric Binding. 5Not supported in Fabric OS 6.0 or later. 6Mode 3 is qualified only with M-EOS switches. 7Not on FCR. 8Supported only locally on the Fabric OS switch. 9All 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. 10To 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. 11Only 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 6.3.2d 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 6.3.2d 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 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 HP B-series Fabric OS 6.3.2d Release Notes 21

Firmware upgrades and downgrades
Upgrading to Fabric OS 6.3.2d 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 6.3.2d 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 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
