HP A7533A - Brocade 4Gb SAN Switch Base Release Note page 20

Virtual Fabrics
Logical Fabric using LISLs (XISLs in base Fabric)
*
Indicates that the feature is available, but not officially tested or supported.
1
Requires M-EOS 9.7 or later for redirection between devices attached to Fabric OS switches, M-EOS
9.8 for redirection between devices attached to M-EOS switches, M-EOS 9.9 for use in McDATA
Open Fabric Mode. Supported EOS platforms include M4400, M4700, M6140, and Mi10K.
2
Allowed only between Fabric OS-based switches.
3
DPS is supported outbound from Fabric OS-based switches. M-EOS can provide reciprocal load
balancing using Open Trunking.
4
SCC policies supported only in conjunction with L2 Fabric Binding support.
5
Not supported in Fabric OS 6.0 or later.
6
Mode 3 qualified only with M-EOS switches
7
Not on FCR.
8
Supported only locally within 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 be operating in IM2
or IM3.
10
To support Frame Reduction to an edge M-EOS 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 FR zones in
McDATA Open Fabric Mode.
12
Supported through FCR only. All routers in the backbone must be running Fabric OS 6.2.x.
NOTE:
FICON Cascaded CUP is qualified only on select platforms.
Firmware upgrades and downgrades
Upgrading to Fabric OS 6.2.1 is allowed only from Fabric OS 6.1.0a or later. The policy to support
only one-level migration, which began with Fabric OS 6.0.0, provides more reliable and robust
migrations for customers. By having fewer major changes in internal databases, configurations, and
subsystems, the system is able to perform the upgrade more efficiently, ensuring a truly seamless and
nondisruptive process for the fabric. The one-release migration policy also reduces the large number
of upgrade-downgrade permutations that must be tested, allowing for the thorough test and verification
of supported migration paths.
The DC04 SAN Director cannot be downgraded to a release earlier than Fabric OS 6.2.0a.
All downgrades from Fabric OS 6.2.0a require a restart and are disruptive to traffic. Platforms
supporting VF must have the feature disabled before downgrading to a release earlier than 6.2.0a.
When downgrading from FOS 6.2.x to 6.1.x, configuration parameters such as switch name in
FOS 6.2 are not persisted.
