- SIz must be installed and enabled on the storage system.
- The serial numbers of the P-VOL and the S-VOL must be defined using one of the following methods:
- Use the same serial number for both the P-VOL and S-VOL.
- Use the serial number for the S-VOL, and enter an additional parameter instead of the serial number for the P-VOL.
SIz and TCz both support PPRC, so a failure to meet these requirements can result in a command being run on a TCz pair instead.
