The asynchronous mirror decision table
When using an asynchronous mirror group pair, some actions and properties require that you
specify either the source or destination. See the following tables: Creating and deleting, Adding
and deleting virtual disks, Editing (setting) properties, and Controlling.
Creating and deleting
Result on destination async mirror
group
Result on source async mirror
group
Async mirror group to
specify
Task
Creates the destination
asynchronous mirror group and
remote copies (virtual disks).
Creates a source asynchronous
mirror group that includes the
specified virtual disks.
SourceCreate an asynchronous
mirror group pair.
Deletes the destination
asynchronous mirror group. Its
virtual disks are retained or
discarded (deleted) as requested.
Deletes the source asynchronous
mirror group. Its virtual disks are
retained.
