Description

Item

Specify the release range. The default is Volume if two or more pairs in the same mirror are
selected. The default is Mirror 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 Mirror.

Range

Volume: Only the specified pair(s) is released.

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 frequency of host I/Os. The pair operations should be performed
under light I/O load conditions.

Mirror: All pairs in the same mirror(s) as the selected pair(s) are released.

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 click Apply, a warning message appears
and processing cannot be continued:

The Preview list contains two or more pairs belonging to the same mirror.

The Range column shows Mirror for at least one of the above pairs.

To be able to continue processing, do either of the following:

Ensure that the Range column shows Volume for all pairs in the same mirror.
