FOS Upgrade and Downgrade Special Considerations The DCX/DCX-4S units running any FOS v6.4.x can be non-disruptively upgraded to FOS v7.0.1. This upgrade is non-disruptive to FC traffic only. When loading FOS v7.0.1 to a DCX chassis with FCOE10-24 blades with Brocade Network Advisor v11.1.1/11.1.1a, there is no warning flagging FCoE traffic disruption. The DCX/DCX-4S units running FOS v6.4.1_fcoe1 can be non-disruptively upgraded to FOS v7.0.1. This upgrade is non-disruptive to both FCoE traffic through FCOE10-24 blades and FC traffic. Non-disruptive upgrade to FOS v7.0.1 on 8G switches is allowed from FOSv6.4.1a or later. Disruptive upgrades to Fabric OS 7.0.1 are allowed and supported from FOS 6.3 (up to a two-level migration) using the optional ―-s‖ parameter with the firmwaredownload command. If there are multiple node EGs (encryption groups) in a fabric, please complete firmwaredownload on one node at a time before downloading on another node. The Brocade 8000 does not support non-disruptive hot code loads (HCL). Upgrading the Brocade 8000 to FOS v7.0 .1 will be disruptive to the I/O through the switch. FC FastWrite , EX_Ports, and TCP byte streaming on FR4-18i must be disabled prior to upgrading to FOS v7.0.1. Failure to do so will cause the upgrade to be blocked. Upgrading a switch currently operating in interopmode 2 or 3 to FOS v7.0.1 is disruptive. The interopmode must be changed to 0 prior to upgrading to FOS v7.0.1, as interopmodes 2 and 3 are not supported on FOS v7.0.1. Changing the interopmode is an offline operation.
