The Preview list shows changes that have been made in the window. Changes appear in the Preview
list before they are applied to the storage systems. If you are sure that the information in the Preview
is correct, click Apply to send the changes to the storage system.
Preview list
When the Preview list shows the changes that have been made, you can only perform the same type
of operation that you have been doing and cannot perform most of the other operations (you can
only view detailed information about journal groups even when the Preview list displays changes).
For example, if you are trying to delete journal groups and the Preview list shows the journal groups
that you want to delete, you are unable to perform any other operations; for example, you are unable
to split mirrors and restore mirrors.
