CAUTION:

When you share an SIz S-VOL with a URz S-VOL as shown in Figure 3.8, the write operation

to the URz P-VOL takes time. Especially, when the SIz pair is in the V-Split status, the write operation to the

URz P-VOL may takes extra time according to the time for copying process of the SIz pair.

In addition, note that if the journal volume size is small, the URz pair may be suspended by failure because

of the shortage of the capacity of its journal volume.
