The conﬁgur

ation shown below is an example of a volume which is functioning as both a Siz T-VOL and

aURzP-VOL

.Thisconﬁguration allows you to use URz to provide remote copies of Siz T-VOLs.

Figure 26 Siz and URz: Shared T-VOL/P-VOL

NOTE:

In the conﬁguration shown, you cannot perform the Siz and URz copy operations at the same time. First

you must create and split the Siz pair, then create the URz pair. If you want to re-synchronize the Siz

pair, suspend the URz pair beforehand. You cannot change the URz pair status while the Siz pair is

in V-Split status.

NOTE:

Usually TCz and URz can share the volumes with Siz. However, in some cases, you cannot create Siz

pairs using the volume shared with TCz and URz.
