In the following example, the SIz T-VOL in Split status is also functioning as a URz primary data
volume. This configuration allows URz to make a remote backup copy of the SIz T-VOL.

Figure 24 SIz T-VOL in Split Status Functioning as URz Primary Data Volume
If a failure occurs and the SIz S-VOL is damaged in Figure 24 on page 84, take the following steps
to copy data from the URz secondary data volume to the SIz S-VOL so that data can be restored
to the SIz S-VOL:
1. Execute the Business Continuity Manager YKDELETE command on the SIz pair to release the
pair (see Figure 25 on page 85).
2. Execute the Business Continuity Manager YKSUSPND REVERSE command on the URz pair to
suspend the pair. After that, execute the YKRESYNC REVERSE command to reverse the copy
direction and re-establish the pair (see Figure 26 on page 85).
3. Execute the Business Continuity Manager YKSUSPND FORWARD command on the URz pair to
suspend the pair. After that, execute the YKRESYNC FORWARD command to change the copy
direction to the original direction and re-establish the pair (see Figure 27 on page 85).
4. Execute the Business Continuity Manager YKSUSPND command on the URz pair to suspend the
pair (see Figure 28 on page 86).
5. Execute the Business Continuity Manager YKMAKE command on the SIz pair to perform copying
in the reverse direction (see Figure 29 on page 86).
6. Execute the Business Continuity Manager YKDELETE command on the SIz pair to release the
pair (see Figure 30 on page 86).
7. Execute the Business Continuity Manager YKMAKE command on the SIz pair to perform copying
in the original direction (see Figure 25 on page 85).
8. Execute the Business Continuity Manager YKSUSPND command on the SIz pair to put the pair
in Split status (see Figure 32 on page 87).
9. Execute the Business Continuity Manager YKRESYNC command on the URz pair to resynchronize
the pair (see Figure 33 on page 87).
