HP XP Continuous Access Software - Manual (Page 162)

To monitor the progress of deleting pairs, click Refresh to update the information in the list, or use the
Pairdisplay pane (see Displaying detailed information about a pair of data volumes ) to monitor the
detailed status of each pair.
NOTE:
To restore a pair that was deleted from the secondary array, delete the pair from the primary array, and
restore the pair using the appropriate initial copy option.
NOTE:
If a pair is deleted, the deletion might take effect on the secondary data volume later than it takes
effect on the primary data volume. Therefore, an error might occur if you reference a pair's status or
manipulate a pair immediately after RAID Manager XP deletes the pair. If such an error occurs, check
the secondary data volume's status and retry referencing the pair status or manipulating the pair.
NOTE:
After the status of a primary data volume changes to SMPL, the secondary data volume may remain with
the status of PSUS or PSUE in the secondary subsystem. Please select the secondary data volume and
delete the pair.

•
Range: Delete range. If you select two or more pairs in the same consistency group, the default is
LU. Otherwise, the default is Group. Also, if the pair status is SMPL, Range is set to LU. If the
pair status is Deleting or Suspending, Range is set to Group.
• LU: Only the specified pairs are deleted.
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 frequency of host I/Os. The pair operations should be performed under
light I/O load conditions.
• Group: All pairs in the same consistency groups as the selected pairs are deleted.
CAUTION:
Do not use this option when deleting pairs at the secondary array during disaster recovery.
