HP StorageWorks Fabric OS 5.X Administrator Guide (AA-RVHWB-TE, September 2005)

112 Administering FICON fabrics
A mode register controls the behavior of the switch with respect to CUP itself, and with respect to the
behavior of other management interfaces.
FICON Management Server mode (fmsmode) must be enabled on the switch to enable CUP management
features. When this mode is enabled, Fabric OS prevents local switch commands from interfering with
host-based management commands by initiating serialized access to switch parameters.
If more than one switch is to be used in the FICON CUP fabric, Secure Fabric OS must be installed. See
”Configuring a high-integrity fabric” on page 109 for more information.
If HP Advanced Zoning is in use, see ”Zoning and PDCM considerations” on page 116.
Setup summary
To set up FICON CUP, perform the following actions in the order stated:
1. Install Fabric OS 4.4.0 or later on an HP StorageWorks switch.
2. For the SAN Director 2/128 only, use the portDisable command to disable (block) port 126.
Port 126 is not supported in a CUP environment. After fmsmode has been successfully enabled, port
126 remains disabled. It cannot be used either as an F_Port or an E_Port. Because port 126 is not
available after enabling fmsmode, first move any fiber connected to port 126 to another free port.
3. Install a CUP license on the switch. See ”Maintaining licensed features” on page 26.
4. Enable FICON management server mode (fmsmode) on the switch. See ”Enabling and disabling FMS
mode” on page 112.
After completing the setup, you can configure CUP attributes (FMS parameters). See ”Setting mode
register bits” on page 114.
Enabling and disabling FMS mode
To enable fmsmode:
1. Connect to the switch and log in as admin.
2. Issue ficoncupset fmsmode enable.
To disable fmsmode:
1. Connect to the switch and log in as admin.
2. Issue ficoncupset fmsmode disable.
The fmsmode setting can be changed whether the switch is offline or online. If fmsmode is changed while
the switch is online, a device reset is performed for the control device and an RSCN is generated with PID
0xDDFE00 (where 0xDD is the domain ID of the switch).
When FMS mode is on, the Fabric OS CLI commands listed here return a switch busy response if they
are issued when the host-based management tool is performing a write operation. This serialization
prevents interference from local switch commands when a host-based management program is being
used to administer the switch.
