NOTE:

The URz pair needs to be in Hold status to form the delta resync operation when the failure occurs.

However, the URz pair status may be changed to Hlde for example when the cache memory or shared

memory error occurs in TCz Synchronous secondary site, or when no journal cannot be obtained in TCz

Synchronous secondary site because of the failure in the master journal volume or occurrence of the

pinned track. If the status of the URz pair for delta resync operation changes to Hlde, follow the steps in

“Restoring a Pair of Data Volumes” on page 165 and change the pair status to Hold again.

Switching the Master Journal Group of URz

When a failure occurs on the primary site in Figure 7 on page 42 (3DC multi-target conﬁguration), the

URz pair for delta resync operation can use the journal group in TCz Synchronous secondary site as the

master journal group. To switch the master journal group, ﬁrst change TCz Synchronous secondary site to

the primary site by using Business Continuity Manager, then perform the delta resync operation on the

primary data volume of the URz pair in Hold status. The following ﬁgure shows an example.
