The following preparations are required for the storage systems in a TrueCopy pair relationship.
- CCI must be LAN-attached to the primary system and the secondary system. For details, see the Command Control Interface User and Reference Guide.
- The primary and secondary systems must be set up for TrueCopy operations. For details, see Shared memory requirements.
- Make sure that the storage system is configured to report sense information by connecting storage system and host. It is required to connect the host to both the primary and secondary systems. If dedicated host cannot be connected to secondary system, connect secondary system and host at primary site.
- Install the data path between the primary and secondary systems. Distribute data paths between different storage clusters and extenders or switches to provide maximum flexibility and availability. The remote paths between the primary and secondary systems must be different than the remote paths between the host and secondary system. For details, see Data path requirements and configurations.
