Virtual Fabrics Yes Yes Logical Fabric using LISLs (XISLs in Base Fabric) No No * 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 OpenTrunking. 4 SCC policies supported only in conjunction with 1.2 Fabric Binding support. 5 Not supported in Fabric OS 6.0 and 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 may be operating in IM2 or IM3. 10 To support Frame Reduction to an edge M-EOS fabric, thee must be at least one Fabric OS switch in the edge fabric to configure Frame Redirection Zones. 11 Only Frame Reduction Zones may 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 via FC Routing only. All routers in the backbone must be running Fabric OS 6.2. NOTE: FICON Cascaded CUP is qualified only on select platforms. Firmware upgrades and downgrades Upgrading to Fabric OS 6.2.0a is allowed only from Fabric OS 6.1.0a or later. The policy to support only one-level migration, which began with FOS 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, taking less time and ensuring a truly seamless and non-disruptive 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 HP StorageWorks DC04 SAN Director Switch may not be downgraded from Fabric OS 6.2.0a. All downgrades from Fabric OS 6.2.0a require a restart and are disruptive to traffic. Platforms supporting Virtual Fabrics must have the feature disabled before downgrading to a version earlier than 6.2.0a. 18

Firmware upgrades and downgrades
Upgrading to Fabric OS 6.2.0a is allowed only from Fabric OS 6.1.0a or later. The policy to support
only one-level migration, which began with FOS 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, taking less time and ensuring a truly
seamless and non-disruptive 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 HP StorageWorks DC04 SAN Director Switch may not be downgraded from Fabric OS 6.2.0a.
All downgrades from Fabric OS 6.2.0a require a restart and are disruptive to traffic. Platforms
supporting Virtual Fabrics must have the feature disabled before downgrading to a version earlier
than 6.2.0a.
