In the Local Replication window, select a P-VOL in the TI Primary Volumes tab or a snapshot group in the Snapshot Groups tab.

From the Action menu, select Local Replication > Operate TI Pairs.

In the TI Pairs window, click Create TI Pairs.

You can specify up to 32 P-VOLs using HDvM - SN.

In Use Primary Volumes of Thin Image Pairs, select Yes or No.

For Yes, continue to the next step. For No, complete the following:
