You can create, update, and copy TC pairs in a consistency group of one primary storage system and one secondary storage system.
Figure notes:
- The TC pair is created in the consistency group specified from CCI.
- I/O requests are received from each application in the open-system server to update data in each volume.
- The
TC copy operation is performed in the consistency group.
For information on creating a TC pair and assigning it to a consistency group using CCI, see the Command Control Interface User and Reference Guide and the Command Control Interface Command Reference.
