Mode register bit settings
3
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.
When the POSC bit=1, the FICON host is allowed to set the switch offline. The bit is set to 1 by
default. If you do not want to allow the host to have permission to set the switch offline, the bit
should be turned off. The state of this bit cannot be changed by the FICON host; it can only be
changed through the command line.
For more information on this command and an example of command output, refer to the Fabric OS
Command Reference Manual.
To display the mode register bit HCP for the switch, enter the ficonCupShow command as shown in
the following example:
switch:admin> ficoncupshow modereg HCP
FICON file access facility
The FICON file access facility (FAF) stores configuration files. This includes the initial program load
(IPL) and other configuration files. The Fabric OS saves the IPL and all other configuration files on
the switch. A maximum of 16 configuration files, including the IPL file, are supported.
You can upload the configuration files saved on the switch to a management workstation using the
configUpload command. Data uploaded using the configUpload command also contains the IPL file
that was current at the time the command was executed.
Refer to the Fabric OS Administrator’s Guide for more information on the configUpload process.
Configuration files uploaded
When you execute the configUpload command, all the files saved in the file access facility are
uploaded to a management workstation (there is a section in the uploaded configuration file
labeled [FICU SAVED FILES] where the files are stored in an encoded format).
Configuration files downloaded with Active=Saved mode enabled
The contents of existing files saved on the switch, which are also present in the “FICON_CUP”
section, are overwritten.
The files in the [FICU SAVED FILES] section of the configuration file, which are not currently on the
switch, are saved on the switch.
The IPL will not be replaced because Active=Saved mode is enabled. A warning message is
displayed in the event log to warn users that the IPL will not be overwritten.
HCP Host control prohibited. When this bit is set on, the host is not allowed to set CUP parameters.
The default setting is 0 (off).
POSC Programmed offline state control. If the bit is set (=1), the command from the host will set the
switch offline. If the bit is off (=0), the command from the host will be rejected and the switch will
not go 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).
