If this option is not selected (it has no  check mark), then availability CHIDs for these CHPIDs are not reset.  – 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.  – 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.  By default, this option is selected.  By default, this option is not selected.  Generally, select this option.  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.
