3 Interoperability with other products and functions
This chapter provides information about Compatible XRC interoperability with other products and
functions.
Volume sharing between Compatible XRC and other copy functions
The P9500 supports concurrent operations of Compatible XRC with other copy functions. The
following table indicates whether Compatible XRC volumes can be shared with other copy functions.

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.

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
By using two Compatible XRC pairs in conjunction, you can maintain three copies of data at
multiple secondary sites for disaster recovery purposes. The following 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.

Using Compatible XRC in conjunction with Continuous Access Synchronous
Z
The P9500 supports the use of Compatible XRC in conjunction with Continuous Access Synchronous
Z (Cnt Ac-S Z) to maintain three copies of critical data at your primary and/or secondary sites for
disaster recovery purposes.
Volume functioning as Compatible XRC P-VOL and Cnt Ac-S Z M-VOL
The following shows the configuration in which a volume is functioning as both a Compatible XRC
P-VOL and a Cnt Ac-S Z M-VOL. In this configuration, data is copied from the primary site to the
first secondary site using Cnt Ac-S Z.
