mirrors
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.

group to specify
Task
Creates the destination asyn-
chronous mirror group and
remote copies (virtual disks).
Creates a source asynchron-
ous mirror group that includes
the specified virtual disks.
Source
Create an asynchronous
mirror group pair.
Deletes the destination asyn-
chronous mirror group. Its vir-
tual disks are retained or dis-
carded (deleted) as reques-
ted.
Deletes the source asynchron-
ous mirror group. Its virtual
disks are retained.

Adds a corresponding remote

Adds a source virtual disk to
the source asynchronous mir-

Add virtual disks to an
