In the list on the Pair Operations pane, verify that the pair was split successfully. If the pair was
split, the pair status is PSUS.
NOTE:
To restore a pair that has already been split, use the Pairresync command (see

•
S-VOL Write: Specifies whether hosts can write data to the secondary data volume. The default
is Disable (that is, do not permit).
• Disable: Hosts cannot write data to the secondary data volume while the pair is split.
• Enable: Hosts can write data to the secondary data volume while the pair is split. This option
is available only when the selected volume is a primary data volume.
•
Range: Split range. If you select two or more pairs in the same consistency group, the default is
LU. Otherwise, the default is Group.
• LU: Only the specified pairs are split.
NOTE:
If you select pairs with PAIR status and pairs with other than PAIR status in the same consistency
group, an unexpected suspension might occur during the pair operations (Pairsplit-r, Pairsplit-S,
and Pairresync) under heavy I/O load conditions. You can estimate whether the I/O load is
heavy or not from the host I/O frequency. The suspend pair operations should be performed
under light I/O load conditions.
• Group: All pairs in the same consistency groups as the selected pairs are split.
NOTE:
If the following conditions are satisfied and you click Apply, a warning message appears and
processing cannot continue:
• The Preset list contains two or more pairs belonging to the same consistency group.
• The Range column displays Group for at least one of the above pairs.
To continue processing, do one of the following:
• Ensure that the Range column displays LU for all pairs in the same consistency group.
• In the Preset list, select all but one pair in the same consistency group, right click the selected
pairs, and select Delete.
•
Suspend Mode: Specifies how to deal with update data that was not copied to the secondary
data volume.
• Flush: When splitting the pair, update data is copied to the secondary data volume. This
is the default.
