Operational state Definition
in contact This cluster is in contact with its peer over the inter-cluster network.
Rebuilds may be in progress. Subject to other system-wide restrictions, I/O
to all distributed virtual volumes in all synchronous consistency groups is
allowed from the perspective of metro node Witness.
cluster partition This cluster is not in contact with its peer and the Cluster Witness
server has declared that two clusters partitioned. Subject to other system-
wide restrictions, I/O to all distributed virtual volumes in all synchronous
consistency groups (with specific preference rule set) is allowed from the
perspective of metro node Witness.
remote cluster isolated or
dead
This cluster is not in contact with its peer and the Cluster Witness Server
has declared that the remote cluster (the peer) was isolated or dead.
Subject to other system-wide restrictions, I/O to all distributed virtual
volumes in all synchronous consistency groups (with specific preference
rule set) is allowed from the perspective of metro node Witness.
local cluster isolated This cluster is not in contact with its peer and the Cluster Witness Server
has declared that the remote cluster (the peer) is the only proceeding
cluster. This cluster must suspend I/O to all distributed virtual volumes in all
synchronous consistency groups regardless of cluster preference.
cluster state unknown This cluster is not in contact with its peer over the inter-cluster network
and is awaiting guidance from the Cluster Witness Server. I/O to all
distributed volumes in all consistency groups is suspended regardless of
bias.
Management Connectivity state Definition
ok The component is reachable.
not reachable The cluster is not reachable.
server not reachable The server is not reachable.
Diagnostic information Definition
Local cluster-x hasn't yet established connectivity
with the server
The cluster has never connected to Cluster Witness Server.
Remote cluster-x hasn't yet established
connectivity with the server
The cluster has never connected to Cluster Witness Server.
Cluster-x has been out of touch from the server
for X days, Y secs
Cluster Witness Server has not received messages from a
given cluster for longer than 60 seconds.
Cluster witness server has been out of touch for
X days, Y secs
Cluster witness server has been out of touch for X days, Y
secs.
Cluster Witness is not enabled on component-X,
so no diagnostic information is available
Cluster Witness Server or either of the clusters is disabled.
Configure Settings
Use this dialog box to configure the inactivity timeout for your connection to the GUI, or to define the data reload policy when
navigating through provisioning storage object views.
GUI idle timeout
WARNING:
A potential security risk can be exposed by setting idle time to greater than 30 minutes. Therefore, if
you set the idle timeout to greater than 30 minutes, a warning will display on this dialog box.
