You can assign ShadowImage volumes to TC pairs, and you can assign TC volumes to SI pairs.
The following table shows the supported configurations.

Note the following when sharing TC volumes with SI volumes.
- L1 and L2 SI pairs can be shared with TC volumes. Both node and leaf S-VOLs are considered secondary volumes by TC.
- SI is recommended for in-system copy operations. However, if SI is not installed, TC can be used to copy within the same storage system. This configuration requires at least one fibre channel or iSCSI cable loop.
