Replication addresses
If any remote port addresses are associated with this volume, when you select the Replication Addresses component,
the Replication Addresses table shows:
• Connected Ports.
• For a remote primary or secondary volume, this field shows the IDs of up to two hosts ports in the local system
that are connected to the remote system. If two ports are connected but only one is shown, this indicates that a
problem is preventing half the available bandwidth from being used.
• For a local primary or secondary volume, this field shows N/A.
• Remote Address. The address of each host port in the remote system through which the volume is accessible.
Replication images
If any replication images exist for this volume, when you select the Replication Images component, the Replication
Images table shows information about each image. For the selected image, the Replication Images table shows:
• Image Serial Number. Replication image serial number.
• Image Name. User-defined name assigned to the primary replication image.
• Snapshot Serial Number. Replication snapshot serial number associated with the image. The replication snapshot
is associated with the replication volume specified in the request.
• Snapshot Name. Replication snapshot name associated with the image. For a secondary replication image, this
value is not filled in until the replication is completed.
• Creation Date/Time. Date and time when the replication image was created on the replication volume.
