HP A7533A - Brocade 4Gb SAN Switch Base Release Note page 13

Secure Fabric OS feature not compatible with Fabric OS 6.x
and later
Fabric OS 5.3.x is the last Fabric OS version compatible with Secure Fabric OS (SFOS). However,
all of the security features of SFOS have been fully integrated into the base Fabric OS, starting with
Fabric OS 5.3.x.
Zoning and fabric operations
When configuring zoning or other fabric-wide settings in a fabric that has products operating with
different versions of Fabric OS, HP recommends that you perform the configuration through an interface
(such as WebTools) to a product with the most recent version of Fabric OS. Some older versions of
Fabric OS do not fully support newer hardware models, and problems may arise when configuring
settings through these older products.
NOTE:
Do not configure zoning through a switch operating with Fabric OS 3.x in a fabric that has products
operating with later versions of Fabric OS.
Prerequisites
Table 1 lists the supported Fabric OS firmware versions. HP recommends using the latest supported
firmware versions to get the greatest benefit from the SAN.

IMPORTANT:
The Fabric OS versions listed in the Earliest compatible version column in
versions supported by HP for connection to switches running Fabric OS 6.3.0c at the time of the Fabric
OS 6.3.0c release.
