M-VOL that time stamp is enabled, at the same time.

Using Two XRC for Mainframe Pairs in Conjunction
By using two XRC for Mainframe pairs in conjunction, you can maintain three copies of data between
secondary sites for disaster recovery purposes.
The following figure shows the configuration in which two XRC for Mainframe operations are performed.
In this configuration, data is copied from the primary site to the first secondary site using XRC for
Mainframe, and then it is copied from the first secondary site to the second one using XRC for
Mainframe.
