You must manually disable ports associated with 0xFE and 0xFF using the portDisable command

Otherwise, these ports will disable automatically when FMS is enabled. Refer to
on page 55 for more information.

Enabling FMS mode disables all ports with OxFE and OxFF addresses.
•
If you enable FMS mode, you will get port-disable messages for physical ports with OxFE or OxFF
FICON addresses.
•
You cannot enable FMS mode when physical ports have OxFE or OxFF FICON addresses with live
devices connected.
•
Port swapping and blade swapping cannot be performed on ports where FMS mode is enabled and
ports have either OxFF or OxFE FICON addresses.
Upgrade considerations
Take the CUP offline before performing an upgrade or downgrade operation. The upgrade can disrupt
CUP exchanges, especially for active RMF sessions.
For Fabric OS 7.0 and later, a FICON CUP license is required to enable FMS mode. Consider the
following when using FMS mode and upgrading from Fabric OS v6.4.0 to v7.0 or later:
•
If using Fabric OS v6.4.0 and FMS mode is enabled, but a FICON CUP license was never installed:
‐
You can manage the port connectivity configuration through management applications
such as Brocade Network Advisor and Web Tools.
‐
The In-band Management feature is not enabled.
‐
After a nondisruptive upgrade from Fabric OS v6.4.0 to v7.0.0 or later:
‐
You can manage the port connectivity configuration using management
applications such as Brocade Network Advisor and Web Tools. The Web Tools
mode register is accessible.
‐
To enable In-band Management, you must install a FICON CUP license and
disable and then re-enable FMS mode.
NOTE
A nondisruptive upgrade is not possible for the Brocade DCX 8510 Backbones, so the
nondisruptive upgrade information does not apply.

If using Fabric OS v6.4 and FMS mode is enabled, but a FICON CUP license was installed and
then removed:
‐
You can manage the port connectivity configuration through management applications
such as Brocade Network Advisor and Web Tools. The FICON CUP Mode Register is
accessible through Web Tools.
‐
Inband Management is enabled, providing you do not disable FMS mode, disable and
then re-enable the switch, or power-cycle the switch.
•
After a nondisruptive upgrade from Fabric OS v6.4.0 to v7.0.0 or later, the following events occur:
