Figure 21 (page 67) through Figure 24 (page 69) show the various URz/SIz configurations which
share volumes.
• URz/SIz configurations which share the URz primary data volume and SIz S-VOL
Figure 21 (page 67) shows an example of a URz primary data volume which is also functioning
as a SIz S-VOL. This configuration allows you to use SIz for on-site data backup in case of a
URz failure, and to use URz to provide remote backup of the SIz S-VOL in case of a SIz failure.

• URz/SIz configurations which share the URz secondary data volume and SIz P-VOL
“Shared URz Secondary Data Volume and SIz S-VOL” (page 68) shows an example of a URz
secondary data volume which is also functioning as a SIz S-VOL. This configuration allows
you to use SIz to provide multiple backup copies of a single URz primary data volume.
