Brocade Fabric OS v7.2.0d Release Notes v1.0

Fabric OS v7.2.0d Release Notes v1.0 Page 5 of 52
Overview
Fabric OS (FOS) v7.2.0d is a patch release based on FOS v7.2.0c. All hardware platforms and features
supported in FOS v7.2.0c are also supported in FOS v7.2.0d.
This release is FICON qualified. Please refer to the Appendix: Additional Considerations for System z (FICON)
Environments section for feature details and notes on deployment in FICON environments.
Due to the impact of defect 491192 and 494570, Brocade recommends all customers planning or using FOS
v7.2.0a, v7.2.0b, and v7.2.0c to upgrade to FOS v7.2.0d.
Note: If customers are already running FOS v7.2.0a, v7.2.0b, or v7.2.0c on their switches, and the
“Custom.index” on the switches are either 0 or 4, they can choose to continue running the same FOS version
because defect 491192 and 494570 do not apply to these switches. To find out the “Custom.index” setting on
a switch, users can run CLI command “configShow |grep Custom”.
