You can configure a consistency group of multiple primary and secondary storage systems when using existing TC or TCz pairs.
The consistency group of multiple primary and secondary storage systems consists of a combination of TC and TCz pairs.
- Create CCI configuration definition file A.
- In CCI, split pairs using CCI configuration definition file A created in step 1.
- In CCI, resume pair operation using CCI configuration definition file A without specifying a consistency group.
- In CCI, split pairs using CCI configuration definition file A.
- Create CCI configuration definition file C for a configuration of multiple pairs of storage systems.
- In CCI, register pairs to a consistency group, and resume pair operation using CCI configuration definition file C.
After removing existing TC or TCz pairs, you can use the procedure to register pairs to a new consistency group when creating TC or TCz pairs.
