By default, for pair split, the maximum multiple copy processing for each pair is set to 48. However, if you disable the Quick/Steady Split Multiplexing local replica option, the multiplicity can be changed to 1. Disable the Quick/Steady Split Multiplexing option if you prioritize host I/O. You can use CCI to modify the local replica options.
You can use one of the following methods to split pairs.
- paircreate –split -fq normal
- When copy of all differential data completes, the pairs are split.
- paircreate –split -fq quick
- Pairs are split immediately after pair split is specified. Use this method if you want to read or write data of the S-VOL immediately after pair split is specified. Remaining differential data is copied to the S-VOL in background after the split.
- paircreate –g <group> -m grp [CTG ID]
- Split all pairs in a consistency group at one time. For details, see the Command Control Interface User and Reference Guide.
