You can assign ShadowImage for Mainframe volumes to TCz pairs, and you can assign TCz volumes to SIz pairs.
The following table shows the supported configurations.

TCz volume |

P-VOL |
Yes |
Yes |
|
S-VOL |
Yes |
No |
Note the following when sharing TCz volumes with SIz volumes.
- L1 and L2 SIz pairs can be shared with TCz volumes. Both node and leaf S-VOLs are considered secondary volumes by TCz.
- When using PPRC, the Split status cannot be distinguished from the V-Split status. If you share an SIz S-VOL with a TCz P-VOL, either use the PPRC command to perform the Steady Split operation, or use CCI to confirm the pair statuses. Perform the Steady Split operation using the CSUSPEND parameters (specify the serial number of the PRIM as MPS00).
