2. Create a peer connection between the backup system and the data center system, if necessary.
3. Create a replication set using the backup system’s volume or snapshot as the primary volume and the data center system as the
secondary system.
4. Replicate the volume from the backup system to the data center system.
Prepare the backup system for disaster recovery after the replication
is complete
1. Delete the replication set.
2. Delete the volume on the backup system. The volume cannot be used as the target of a replication and deleting it will free up space.
3. Create a replication set using the data center system’s volume as the primary volume and the backup system as the secondary
system.
4. Replicate the volume from the data center system to the backup system.
Viewing replications
The Replications topic shows a tabular view of information about peer connections, replication sets, and snapshot history of local
snapshots associated with a selected replication set. For more information about replication, see About replicating virtual volumes on page
31.
Peer Connections table
The Peer Connections table shows the following information. By default, the table shows 10 entries at a time.
• Name. Shows the specified peer connection name.
• Status. Shows the status of the peer connection:
○ Online—The systems have a valid connection.
○ Offline—No connection is available to the remote system.
•
Health. Shows the health of the component:
OK, Fault, or Unknown.
• Type. Shows the type of host ports being used for the peer connection: FC or iSCSI.
• Local Ports. Shows the IDs of host ports in the local system.
• Remote Ports. Shows the IDs of host ports in the remote system.
To see more information about a peer connection, hover the cursor over the peer connection in the table. The Peer Connections panel
that appears contains the following information:
NOTE: If the health is not OK, the health reason and recommended action are shown to help you resolve problems.
Table 25. Peer Connections
Panel Information displayed
Peer Connections Name, serial number, connection type, connection status, local host port name and IP address, remote host port
name and IP address, health
Replication Sets table
The Replication Sets table shows the following information. By default, the table shows 10 entries at a time.
NOTE:
If you change the time zone of the secondary system in a replication set whose primary and secondary systems
are in different time zones, you must restart the system to enable management interfaces to show proper time values
for replication operations.
• Name. Shows the replication set name.
• Primary Volume. Shows the primary volume name. For replication sets that use volume groups, the primary volume name is volume-
group-name.* where .* signifies that the replication set contains more than one volume. If the volume is on the local system, the
icon appears.
