Table 10 describes the host pair status reporting for SIz, URz volumes, and SIz/URz shared volumes; and
SI390 volumes, Universal Replicator for z/OS volumes, and ShadowImage and Universal Replicator for
z/OS shared volumes. Table 11 lists the currency of the data on shared SI390/URz volumes based on the
SI390 and URz pair status.
The configuration shown in the following figure is an example of a volume that is functioning as both an
SI390 S-VOL and a TC390 M-VOL. With this configuration, you can:
• Use SI390 to provide on-site backup copies of TC390 M-VOLs.
• Use TC390 to provide remote backup copies of SI390 S-VOLs.
