Fabric Manager 5.x administrator guide 201
16 FICON and CUP
NOTE: FICON is not supported on HP B-Series Fibre Channel switches. The FICON information in this
document is included for reference only.
FICON is a protocol used between IBM (and compatible) mainframes and storage. FICON is supported
on switches running Fabric OS 4.1.2 and later. FICON Control Unit Port (CUP) is a protocol for managing
FICON directors. CUP is used by IBM mainframe management applications to provide in-band
management for ESCON and FICON.
Host-based management programs manage the switches using the CUP protocol by sending commands to
the emulated Control Device implemented by the Fabric OS. A switch that supports CUP can be controlled
by one or more host-based management programs or by Enterprise Fabric Connectivity Servers (EFC
Servers). The director allows control to be shared between host-based management programs and EFC
Servers.
To monitor a FICON CUP environment in Fabric Manager, you must have the following (all done through
Advanced Web Tools):
• A CUP license installed on a FICON director
• FICON Management Server (FMS) mode enabled on the FICON director
• CUP attributes (FMS Parameters) configured for the FICON director
NOTE: See the HP StorageWorks Fabric OS 5.x administrator guide for information on enabling FMS
mode with Advanced Web Tools. You can also enable FMS mode using the command ficoncupset
fmsmode enable in the CLI. See the HP StorageWorks Fabric OS 5.x diagnostics and system error
messages reference guide for additional CLI information.
This chapter provides information on using Fabric Manager to identify switches with FMS enabled, to
activate current or stored CUP configurations, to monitor link incidents, and to identify port zone conflicts,
switches with insistent domain IDs (IDIDs), and ports that have completed the request node identification
(RNID) exchange.
You can use Fabric Manager in a FICON CUP environment to directors (when FMS mode is enabled on
those directors) for:
• Identifying switches with FMS enabled, next
• Activating the current port connectivity configuration, page 202
• Activating a stored port connectivity configuration, page 203
• Identifying port zone conflicts, page 205
• Identifying switches with insistent domain IDs, page 205
• Identifying ports that have completed the RNID exchange, page 206
• Monitoring link incidents, page 206
Identifying switches with FMS enabled
NOTE: See the HP StorageWorks Fabric OS 5.x administrator guide for information on enabling FMS
mode with Advanced Web Tools. You can also enable FMS mode using the command ficoncupset
fmsmode enable in the CLI. See the HP StorageWorks Fabric OS 5.x command reference guide for
additional CLI information.
