274 Administering FICON fabrics
Using FICON CUP
Host-based management programs manage switches using CUP protocol by sending commands to an
emulated control device in Fabric OS. A switch that supports CUP can be controlled by one or more
host-based management programs.
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. Refer
to ” Configuring a high-integrity fabric ” on page 270 for more information.
If Advanced Zoning is in use, refer to ” Zoning and PDCM considerations ” on page 279.
Setup summary
To set up FICON CUP, perform the following tasks
in order
:
1. Install Fabric OS v4.4.0 or later on an HP StorageWorks switch.
2. For SAN Director 2/128 only : Use the
portDisable
command to disable (block) port 126.
For 4/256 SAN Director only : Use the
portDisable
command to disable (block) ports 254 and
255.
Port 126 (Core Switch 2/64) and 254 and 255 (4/256 SAN Director) are not supported in a CUP
environment. After
fmsmode
has been successfully enabled, these two ports remain disabled and
cannot be used either as an F_Port or an E_Port. Because these ports are not available after enabling
fmsmode
, you should first move any fiber connected to either of them to another free port.
If you have a B-Series MP Router blade in your 4/256 SAN Director, then sixteen virtual ports are
disabled when you enable
fmsmode
.
3. Install a CUP license on the switch. Refer to ” Adding and removing FICON CUP licenses ” on
page 279.
4. Enable FICON management server mode (
fmsmode
) on the switch. Refer to ” Enabling and disabling
FICON management server mode ” on page 275.
After completing the setup, you can configure CUP attributes (FMS parameters). Refer to ” Setting mode
register bits ” on page 278.
NOTE: After a nondisruptive firmware download from pre-5.2.x firmware to 5.2.x firmware (or
higher), you must disable fmsmode and reenable it, so that FICON channels will query updated
FICON parameters for CUP. See ” Enabling and disabling FICON management server mode ” on
page 275.
