view detailed information about the error, right-click the error code, and select Error Detail.
An error message appears providing detailed information about the error.
10. 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
Restoring a pair of data volumes ).

•
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.
