Paircreate dialog box to the storage system.
When the initial copy operations to create the L2 pairs starts, the Pair Operation window shows
the new pairs with COPY(PD) status and the progress (%) of the initial copy operations.
To split an L2 pair, you must first split the L1 pair (L1 status = PSUS). The reverse and quick restore
pairresync operations cannot be used for L2 pairs.
on page 70 shows the relationship between
the L1 pair status and the availability of Business Copy pair operations on the associated L2 pairs.

Note*1:
You can only resynchronize L2 pairs in Normal Copy or Quick Resync mode. Note that you
cannot perform backward resynchronization (that is, Reverse Copy or Quick Restore).
Note*2:
In order to split L2 pairs, you need to change the status of the L1 pair to PSUS at first.
on page 71 shows the relationship between the L2 pair status and the availability of pair
operations on the associated L1 pairs. (CMD RJT = command rejected.) If you delete an L1 pair that
contains an L2 pair, the L2 pair becomes the L1 pair.
