GLYPH<SM590000> Process the CU Priorities and Automatic Mapping: 

– Reset CHPIDs assigned by Automatic Mapping : Selecting this option resets all CHPIDs that were processed by prior availability runs in this session. 

By default, this option is selected. 

– Reset CHPIDs assigned by Manual Mapping : Selecting this option resets CHPIDs that were assigned a CHID in the Manual window. If this option is not selected (it has no check mark), then availability CHIDs for these CHPIDs are not reset. 

By default, this option is not selected. 

– Reset CHPIDs assigned by IOCP (Potential re-cabling) : If some of the CHPIDs are assigned in the IOCP Input file, selecting this option resets the CHPIDs. Selecting this option might require recabling after availability assignments. 

Generally, select this option. 

– Reset CHPIDs assigned by CMT for config files : The CFReport indicates that you are doing an MES/upgrade, and you have channels or CHPIDs (or both) that might have configuration files that are currently associated with them. The MES/upgrade might move some of those channel cards. 

Regardless of whether the channels are moving or not, the CHPID Mapping Tool either assigns CHIDs to the logical CHPID definitions to keep the CHPID definition associated with its current configuration file, or moves the definition to the new location where the channel is moving. 

If you reset the CHPID Mapping Tool assignments, back up the configuration file data before the MES, and restore that data to the new location (the CHID where the affected CHPIDs are assigned) before you use the CHPIDs. 

By default, this option is not selected. 

If no options are selected, availability works only on CHPIDs that do not have CHIDs assigned. 

To give the CHPID Mapping Tool the most choices when you use the availability option, select Reset CHPIDs assigned by IOCP . 

Attention:  If you run Reset CHPIDs assigned by IOCP , it resets any previously mapped CHPID assignments and can result in recabling of the server. 

However, if you select Reset CHPIDs assigned by Automatic Mapping , review the intersects from availability processing carefully to ensure that preserving the prior CHPID-to-CHID relationship does not cause unacceptable availability.
