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 t

he 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. Execut

e 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. Execu

te 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 pa

ir (see Figure 33 on page 87).
