Displaying mode register bit settings The mode register bits are described in Table 93. Table 93 FICON CUP mode register bits POSC UAM ASM DCAM ACP HCP Programmed offline state control. When this bit is set on, the host is prevented from taking the switch offline. The default setting is 1 (on). User alert mode. When this bit is set on, a warning is issued when an action is attempted that will write CUP parameters on the switch. The default setting is 0 (off). Active=saved mode. When this bit is set on, all CUP configuration parameters are persistent, meaning that they will be saved in nonvolatile storage in the initial program load (IPL) file that is applied upon a cold reboot or a power cycle. The default setting is 1 (on). Switch clock alert mode. When this bit is set on, a warning is issued when the date, tsClockServer, or tsTimeZone commands are entered to set the time and date on the switch. The default setting is 0 (off). Alternate control prohibited. Because the Fabric OS CLI, Web Tools, and Fabric Manager are considered to be switch consoles, this bit has no effect on their operation. Attempts to set CUP parameters through SNMP are denied when this bit is set on. The default setting is 1 (on). Host control prohibited. When this bit is set on, the host is not allowed to set CUP parameters. The default setting is 0 (off). The ficoncupshow modereg command displays the mode register bit settings for the switch. A display of 0 indicates that the mode register bit is set to off; 1 indicates that the bit is set to on. The command format is: ficoncupshow modereg [bitname] where bitname is one of the mode register bits described in Table 93. To display all mode register bit settings for the switch: switch:admin> ficoncupshow modereg POSC UAM ASM DCAM ACP HCP 1 0 1 0 1 0 To display the mode register bit HCP for the switch: switch:admin> ficoncupshow modereg HCP HCP 0 Setting mode register bits Use the ficoncupset modereg command to set the FICON CUP mode register bits for the local switch. Consider the following when changing mode register bits: • As required by the CUP protocol, the UAM bit cannot be changed using this command. • All mode register bits except UAM are saved across power on/off cycles; the UAM bit is reset to 0 following a power-on. • Mode register bits can be changed when the switch is offline or online. If the ACP or HCP bits are changed when the switch is online, they will take effect any time between the completion of the current command and the end of the CCW command chain (or the next alternate manager operation). To set the mode register bits: 1. Connect to the switch and log in using an account assigned to the admin role. 2. Issue the following command: ficoncupset modereg [bitname] 0 | 1 434 FICON fabrics
