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 sta

tus 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,thedefaultisGroup. Also, if the pair status is SMPL, Range is set to LU.Ifthe

pair status is Deleting or Suspending, Range is set to Group.

•LU:Onlythespeciﬁed 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.
