18 The following switch parameters being read or modified can cause the FICON CUP Busy error: • Mode Register • Port Names (also called Port Address Name) • PDCM and Port Connectivity Attributes • Switch enable/disable • Switch name change To display the control device state 1. Click a FICON-enabled switch from the Fabric Tree. 2. Launch the Switch Admin module as described on page 3-3. 3. Click the FICON CUP tab. The FICON CUP tabbed page displays, with the FICON Management Server subtabbed page in front (see Figure 18-1 on page 18-3). All attributes on this tab are read-only until FMS Mode is enabled. The control device state is displayed as neutral or switched in the Control Device Allegiance field. If FMS mode is enabled, and the control device state is unavailable, the FICON CUP Busy Error is displayed. Click Reset Allegiance in the error message to reset the control device state to its correct state (see Figure 18-2). Configuring CUP Port Connectivity In the Port Connectivity subpanel (shown in Figure 18-3 on page 18-9), you can manage the configuration files and active configuration. All CUP configuration files and the active configuration are listed in a table. The active configuration is listed as "Active Configuration*" and the description in the table is "Current active configuration on switch." The other special configuration file is the IPL. Any other files displayed are user-defined configurations and are stored on the switch. You can create, activate, copy, or delete saved CUP port connectivity configurations; however, you can only edit or copy a configuration while it is active.You can also activate, edit, or copy the IPL configuration. You must have FMS mode enabled before you can make any changes to the configurations. Click Refresh to get the latest configuration file list from the switch. When creating a new configuration or editing an existing configuration, keep in mind that Web Tools port name input is restricted to printable ASCII characters. Therefore, when Web Tools displays a port name, if there are characters beyond printable ASCII characters (which would have been created by the Host Program), those characters are displayed as dots (.). When initially installed, a switch allows any port to dynamically communicate with any other port. Two connectivity attributes are defined to restrict this any-to-any capability for external ports: Block and Prohibit. Block is a port connectivity attribute that prevents all communication through a port. Prohibit is the port connectivity attribute that prohibits or allows dynamic communication between ports when a port is not blocked. Each port has a vector specifying its Prohibit attribute with respect to each of the other ports in the switch. This attribute is always set symmetrically in that a pair of ports is either prohibited or allowed to communicate dynamically. Web Tools Administrator's Guide Publication Number: 53-0000194-01 18-7
