When splitting a pair using the pairsplit command, you can specify settings for read/write access control for the P-VOL and S-VOL in consistency groups after the pairsplit operation.
These settings are specified using CCI. The CCI settings for TC are optional.
The following tables show the effects of the settings on read and write access.
