5.3.12 Managing a Metro Mirror session through the GUI
In this scenario we will run through a number of actions against a defined Metro Mirror
session. In this case we will use the previously defined session
ess_mmfofb. This session is
defined as a Metro Mirror Failover / Failback copy type. The nature of this copy type is cyclical
as Figure 5-103 displays.

As shown in Figure 5-104 on page 148, click the hyperlink of the session name. This will open

Figure 5-107 on page 150 shows that the session went into Warning state. This is because
the copy sets are in the process of synchronization and perform an initial full copy.

We can check on the progress of the synchronization via the View Progress command in the
panel. Figure 5-108 shows the progress of the initial full copy process.

Once all volumes are consistent and synchronized the status will change to green as shown
in Figure 5-109.

Now that the volumes of the copy sets are synchronized the next command entered is a
suspend command to begin the failover process. Remember that once the Suspend command
is issued all host I/O is temporarily halted.
Select the Suspend command from the drop-down menu and click the Go button as shown in
Figure 5-110 on page 152.
