Figure 70 Delete Pair Window
The Delete Pair window displays the following:
•
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.
◦ Volume: Only the specified pair(s) will be released. If pairs are selected 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 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 disaster recovery.
If the following two conditions are satisfied and you select Apply, a warning message will be
displayed and processing cannot be continued:
◦ The Preview list contains two or more pairs belonging to the same mirror.
◦ The Range column displays Group for at least one of the above pairs.
