HP StorageWorks Storage Mirroring for Linux User's Guide (T2558-96317, June 2009)

6 - 2
 All To One—This option replicates data from the source to a single volume on the target.
The pre-defined path is /source_name/replication_set_name/volume_name. If you are
replicating from multiple volumes on the source, each volume would be replicated to the
same volume on the target.
 One To One—This option replicates data from the source to the same directory structure
on the target. For example, /var/data and /usr/files on the source will be replicated to
/var/data/ and /usr/files, respectively, on the target.
 Custom Location—If the predefined options do not store the data in a location that is
appropriate for your network operations, you can specify your own custom location where
the replicated files will be sent. Click the target path and edit it, selecting the appropriate
location.
 Start Mirror on Connection—Mirroring can be initiated immediately when the connection is
established. If mirroring is not configured to start automatically, you must start it manually
after the connection is established.
 Start Replication on Connection—Replication can be initiated immediately when the
connection is established. If replication is not configured to start automatically, you must start
it manually after the connection is established. If you disable this option, you will need to
perform a mirror prior to beginning replication to guarantee integrity.
3. If desired, you can configure mirror settings before establishing your connection. Select the
Mirroring tab on the Connection Manager.
 Full Mirror—All files in the replication set will be sent from the source to the target.
 Difference Mirror—Only those files that are different based size or date and time (depending
on files or block devices) will be sent from the source to the target.
 Only send data if the source’s date is newer than the target’s date—Only those
files that are newer on the source are sent to the target.
WARNING: Data integrity cannot be guaranteed without a mirror being performed. This option
is recommended for the initial connection.
NOTE: If you are using a database application, do not use the newer option unless
you know for certain you need it. With database applications, it is critical that
all files, not just some of them that might be newer, get mirrored.
