When you register the split time, the split type will be Quick Split.

4.

Perform the pair create operation.

5.

Perform the pair split operation on the SIz pairs that are created for At-Time Split function.

The At-Time Split option is enabled, and data in all S-VOLs in the same CTG is created in the
corresponding T-VOLs at the time when the pairsplit request is received by the storage system.

CAUTION:

On executing the At-Time Split function:

Change the status of pairs in the same CTG according to the copy group.

If you are going to execute the At-Time Split function successively, before you execute the
function for the second time, verify that status of all the pairs in the same CTG is changed to
the status which is specified by the YKEWAIT command. For detailed information about the
YKEWAIT command, see the HP XP for Business Continuity Manager Software Messages.

If you do not follow the above mentioned caution, the data in the S-VOL when the Split operation
is performed by the At-Time Split function may not be copied to the T-VOL.
