Blocking target paths
You can block writing to the paths on the target that contain the copy of the replication set data. This keeps the data from
being changed outside of Storage Mirroring processing. To block the replication set data paths on the target, right-click the
connection on the right pane of the Management Console and select
Block Target Path(s). To unblock the paths, right-clikc
the connection and deselect Block Target Path(s).
Disconnecting a connection
To disconnect a Storage Mirroring connection, right-click the connection on the right pane of the Management Console and
select
Disconnect. The source and target will be disconnected.
NOTE: 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.
Do not block your target paths if you are using Full-Server Failover because system state data will not be able
to be written to the target.
NOTE: If a connection is disconnected and the target is monitoring the source for failover, you will be prompted if you
would like to continue monitoring for a failure. If you select
Yes, the Storage Mirroring connection will be
disconnected, but the target will continue monitoring the source. To make modifications to the failure
monitoring, you will need to use the Failover Control Center. If you select
No, the Storage Mirroring
connection will be disconnected, and the source will no longer be monitored for failure by the target.
If a connection is disconnected while large amounts of data still remain in queue, the Management Console may
become unresponsive while the data is being flushed. The Management Console will respond when all of the
data has been flushed from the queue.
