7. Execute the YKQUERY command on the Cnt Ac-J Z copy group between the primary site and
the remote site to confirm that the following conditions exist:
•
The number of Cnt Ac-J Z pairs is equal to the number of Cnt Ac-S Z copy pairs and is
also equal to the number of delta resync pairs to be created.
•
The copy pair status is DUPLEX.
•
The copy direction is from the primary site to the remote site.
8. On the Cnt Ac-J Z copy group for the delta resync function, execute the delta resync pair
creation command (the YKMAKE command with the HOLD parameter specified).
9. Monitor the Cnt Ac-J Z copy group for the delta resync function (by executing the YKEWAIT
command with the GOTO(HOLD) parameter specified) until all pairs have entered the HOLD
status.
For the action to be taken if the YKEWAIT command abnormally terminates, see “Actions to
be Taken When the Delta Resync Function Cannot be Set Up or Operated Successfully”
(page 445)
.
10. Set up a delta resync control path between storage systems by using Remote Web Console.
Copy pair status transitions for Delta Resync pairs
Figure 88 (page 213) shows copy pair status transitions for delta resync pairs.
If YKRESYNC DELTAJNL is executed for a copy pair in the HOLD status, such a copy pair first
changes to the PENDING status just as when YKRESYNC ALLJNL is executed, and then changes
to the DUPLEX status.
