Figure 85 Delete Pair Window
The Delete Pair window displays the following settings:
•
Range: Allows you to specify the release range. The default is Volume if two or more pairs in
the same mirror are selected. The default is Group if not. Also, if the pair status is Simplex,
Range is set to Volume. If the pair status is Deleting or Suspending, Range is set to Group.
◦
Volume: Only the specified pair(s) will be released.
NOTE:
If you select pairs with Duplex status and other than Duplex status in the same
mirror, an unexpected suspension may occur during the pair operations (Suspend Pair,
Delete(release) Pair, and Resume Pair) 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 mirror(s) as the selected pair(s) will be released.
CAUTION:
Do not use this option when releasing pairs at the secondary storage system
during a disaster recovery.
