Table columns and descriptions include:

Column	Description
Partner Tapeplex	The partner tapeplex in the cluster.
Partner VTSS	The secondary or receiving VTSS in the cluster.
CLINK ID	The CLINK ID that has been assigned to the CLINK within the VTSS
Channel ID	The back-end channel interface to which the CLINK is connected.
IPIF ID	The IPIF ID of the CLINK
Cluster	The cluster name if the CLINK is used for replication of VTVs within the tapeplex and is part of a cluster. The VTSS name in the Partner VTSS column indicates the other VTSS that operates in the cluster.
Status	One of the following: Maint: The link has failed or it has been varied into maintenance mode. Offline: The link is offline and unavailable to all hosts and VTSSs. ONLINE: The link is online and available to all hosts and VTSSs. ON-SYNC: Available for synchronous replication. ON-ASYNC: Available for asynchronous replication. P_OFFLINE: The link is pending offline. P_ONLINE: The link is pending online. RECOVERY: The link is being reset following an error or a vary online operation. UNUSABLE: Not available for replication due to hardware errors or assigned-elsewhere conditions. UUI ERR: This is a CLINK defined for electronic export and it has been unable to contact the remote VTCS. There should be messages in the HSC JOBLOG that indicate the reason for the problem. This could include problems with the definitions, the local SMC, or the remote HTTP server on the remote VTCS.
Usage	One of the following: ASSIGNED: Link is assigned to the host in the HOST field but is not currently replicating. This usage occurs when VTCS is starting or terminating link use or is attempting error recovery on the link after a replication failure. FREE: Link is idle (not doing replications). REPLICATING: Link is actively doing replications.
MVS Host	The host that the link is assigned to
Partner VTD	The address of the VTD on the partner VTSS that forms the other end point to the connection. For a cluster link, the MVS address of the VTD is reported. For an electronic export link, this is not possible as there is no access to the other tapeplex configuration. In this case, only the ordinal number of the VTV is reported.
Replication Capability	Indicates the CLINK is available for synchronous or asynchronous replication.
Refreshed	The date and UTC time the data was stored or last updated.

Table columns and descriptions include:

Column	Description
Cluster	The cluster name.
Direction	The direction of the link between the VTSSs, one of the following: -----> or <----- indicates the direction of VTV replication in Uni-Directional Cluster. VTVs can only be replicated from the Sending to the Receiving VTSS. <----> indicates that the VTSSs are configured as a Bi-Directional (Peer-to-Peer) Cluster. VTVs can be replicated from either VTSS to the other.
Partner VTSS	The partner VTSS in the cluster.
Mode	One of the following cluster operating modes: ASYNC-REPLICATE: Both VTSSs in the cluster are online to VTCS. Production workload can go to either VTSS, but for a unidirectional (primary/secondary) cluster, VTVs can only be replicated from the sending VTSS. Synchronous replication is not enabled across the cluster. SYNC-REPLICATE: Both VTSSs in the cluster are online to VTCS. Production workload can go to either VTSS, but for a unidirectional (primary/secondary) cluster, VTVs can only be replicated from the sending VTSS. Synchronous replication is enabled across the cluster. DEGRADED: One of the two VTSSs in a bidirectional peer-to-peer cluster is either offline or quiesced. Production workload can go the remaining online VTSS. VTVs requiring replication, however, are allocated to the remaining VTSS only if no other full-function clusters are available and suitable. In this case, replicate VTVs are migrated immediately with keep and queued for replication when the other VTSS comes online. When the other VTSS comes online, VTCS reconciles the contents of both VTSSs. DEGRADED SECONDARY: The primary is online to VTCS and the secondary is either offline or quiesced. Workload can run on the primary. VTVs requiring replication, however, are allocated to the primary only if no other full-function clusters are available. In this case, replicate VTVs are migrated immediately with keep and are queued for replication, which occurs when the secondary comes online. DEGRADED PRIMARY: The secondary is online to VTCS and the primary is either offline or quiesced. Workload can run on the secondary. VTVs requiring replication, however, are allocated to the secondary only if no other full-function clusters are available. When the primary comes back online, VTCS reconciles the contents of the primary and secondary. NON-OPERATIONAL: No workload is possible on this cluster. CLINKS OFFLINE: All defined CLINKs are offline. No workload is possible on this Cluster. ONLY SECONDARY: The Secondary is online to VTCS and the Primary has no CLINKs online. Workload can run on the Secondary. VTVs requiring replication, however, are allocated to the Secondary only if no other Full Function Clusters are available. ONLY PRIMARY: The Primary is online to VTCS and the Secondary has no CLINKs online. Workload can run on the Primary. VTVs requiring replication, however, are allocated to the Primary only if no other Full Function Clusters are available. In this case, Replicate VTVs are migrated immediately with keep and are queued for replication.
Replication Capability	Indicates the cluster is available for synchronous or asynchronous replication.
Refreshed	The date and UTC time the data was stored or last updated.
