CDF Functions Description
CDF/NCP Discrepancy - - - - - - - - - - - - - - - - - - - - - ,
A discrepancy between the CDF and the NCP generation may be the cause
of NCP problems. When updating the CDF, make sure the corresponding
change is reflected in the NCP generation, if applicable.
The CDF function allows the user to create, display, verify, and modify the con-
figuration data file (CDF) located on the MOSS disk.
The CDF contains the machine configuration, and can be:
• Manually updated from the keyboard (when authorized).
• Easily retrieved by an application running in a MOSS environment, such as
diagnostics, IPLs, MOSS applications.
• Selectively displayed.
The available CDF functions are:
• Display/update
• Create
• Upgrade
• Verify.
Each time there is a hardware change, the CDF must be updated to reflect this
change.
What Can You Do, According to MOSS State
• Global hardware sensing:
The create, upgrade, and verify functions allow performing a global hard-
ware sensing. This corresponds to hardware changes performed while no
control program is running (MOSS alone state on both CCUs).
Create
The create function is available only to the CE (3745 in maintenance
mode). The MOSS must be in the MOSS alone state on both CCUs.
At the end of the hardware sensing, all the information previously
entered manually is lost and set to the initial default value (as for the
first create).
Upgrade
The upgrade function is available tb the CE and the customer. The
MOSS must be in the MOSS alone state.
When the function has completed, the information previously entered
manually is kept (manual fields are not updated). Use the
display/update function to check and update the manual information as
required. For example, if you added a channel adapter, manually enter
the NSC address and the other required CA information.
Verify
The verify function is available only to the CE (3745 in maintenance
mode). The MOSS must be in the MOSS
alon~
state on both CCUs.
