available must be equal to or greater than the on-disc size of the sparse
file.
If you are mirroring and replicating multiple mount points, your directory
mapping must not create a cycle or loop. For example, if you have the c:
volume mounted at d:\c and the d: volume mounted at c:\d, this is a
circular configuration. If you create and connect a replication set for either
c:\d or d:\c, there will be a circular configuration and mirroring will never
complete.
● 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.
Warning:
Data integrity cannot be guaranteed without a mirror being performed.
This option is recommended for the initial connection.
● 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.
● Block Target Path(s) on Connection—You can block writing to the data
located in the target paths. This keeps the data from being changed outside
of Storage Mirroring Recover processing. If you are going to use failover, any
target paths that are blocked will automatically be unblocked during the
failover process so that users can modify data on the target after failover.
During a restoration, the paths are automatically blocked again. If you failover
and failback without performing a restoration, the target paths will remain
unblocked. You can manually block or unblock the target paths by right-
clicking on a connection.
3. If desired, you can configure mirror settings before establishing your connection.
Select the Mirroring tab on the Connection Manager.
