Transition
Indications
If the operational status is not OK, this field lists the reasons why.
Transition
Progress
Displays the progress of the transition, if available.
Health Indicates the health of the cluster. See metro node cluster status.
Health
Indications
Lists the reasons for the unhealthy state.
Operational
Status
Indicates how the cluster is functioning. See metro node cluster status.
To view version details for the cluster, click Version Details at the bottom of the window.
Metro node Witness status
The metro node Witness status view shows the following information:
Name The name of the component. For a metro node cluster, this is the name of the cluster in the metro node
Metro configuration. For the metro node Witness server this is server.
Private IP
Address
Private IP address of the Cluster Witness Server VM used for cluster witness-specific traffic.
Public IP Address Public IP address of the Cluster Witness Server VM used as an endpoint of the IPsec tunnel.
Admin State Identifies whether metro node Witness is enabled or disabled. The Admin states are defined in the
following table.
Operational state Operational state of the corresponding component. The Operational states are defined in one of the
following tables.
Management
Connectivity
Reachability of the specified Witness component over the IP management network from the management
server where the CLI command is run. The Management Connectivity states are defined in one of the
following tables.
Diagnostic
information
String generated based on the analysis of the data and status information reported by the corresponding
component. The diagnostic information is defined in one of the following tables.
Admin state Definition
Enabled Metro node Witness functionality is enabled on this component.
Disabled Metro node Witness functionality is disabled on this component.
Inconsistent All Cluster Witness components are reachable over the management network but
some components report their administrative state as disabled while others report it
as enabled. This is a rare state which may result failure during enabling or disabling.
Unknown This component is not reachable and its administrative state cannot be determined.
Operational state Definition
For Cluster Witness server:
clusters in contact Both clusters are in contact with each other over the inter-cluster network.
cluster partition The clusters are partitioned from each other over the inter-cluster network,
and the Cluster Witness server can still talk to each cluster.
cluster unreachable One cluster has either failed or become isolated (that is, partitioned from its
peer cluster and disconnected from the Cluster Witness server).
unknown Cluster Witness server does not know the states of one or both of the
clusters and needs to learn them before it can start making decisions. The
Cluster Witness server assumes this state upon startup.
For metro node clusters:
