Manually transfer operations from the data center system to the backup
system
1. Create a snapshot of the secondary volume, use a snapshot history snapshot, or delete the replication set.
2. Map the snapshot or the secondary volume, depending on the option that you choose in step 1, to hosts.
Restore operations to the data center system
1. If the old primary volume still exists on the data center system, delete it. The volume cannot be used as the target—a new
“secondary” volume will be created and deleting it will free up available space.
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 32.
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.
