Notes:
1. An S-VOL of Compatible XRC cannot be used as an Compatible XRC P-VOL within the same Compatible XRC
session, but it can be used as an Compatible XRC P-VOL in another Compatible XRC session.
2. When the Compatible XRC P-VOL and the BC Z S-VOL are the same volume, you cannot use the Reverse Copy or
Quick Restore commands of BC Z.
Using two Compatible XRC pairs in conjunction
You can use two Compatible XRC pairs in conjunction to maintain three copies of data at multiple
secondary sites for disaster recovery purposes. The following figure shows the configuration in
which two Compatible XRC operations are performed. Data is copied from the primary site to the
first secondary site using Compatible XRC, and then the same data is copied from the first secondary
site to the second secondary site using Compatible XRC.
