Table 7-2 FICON CUP Mode Register Bits
POSC 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).
UAM 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).
ASM 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).
DCAM 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).
ACP 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).
HCP Host control prohibited. When this bit is set on, the host is not allowed to set CUP
parameters. The default setting is 1 (on).
