FMS mode and FICON CUP
3
FMS mode and FICON OxFE or OxFF ports
OxFE and OxFF are assigned to the CUP and cannot be associated with any physical port with FMS
mode enabled. Therefore, note the following when using FMS mode:
• You must manually disable ports associated with 0xFE and 0xFF using the portDisable
command to before you can enable FMS mode, but only if there is an active device connected
to these ports. Otherwise, these ports will disable automatically when FMS is enabled. Refer to
“Disabling ports 0xFE and 0xFF” on page 38 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 to v7.0 or later:
• If using Fabric OS v6.4 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 the Brocade Network Advisor and Web Tools.
- The Inband 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 programs
such as the Brocade Network Advisor and Web Tools. The Web Tools mode register is
accessible.
 To enable Inband Management, you must install a FICON CUP license and disable,
then re-enable FMS mode.
NOTE
The preceding information does not apply to the Brocade DCX-8510 models as a
nondisruptive upgrade is not possible.
• If using Fabric OS v6.4 and FMS mode is enabled, but a FICON CUP license was installed, then
removed:
- You can manage port connectivity through management applications such as the 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, then
re-enable the switch, or power-cycle the switch.
