Table 5. cluster summary field descriptions (continued)
Field Description
● If no meta-volume has been configured, operational status
is transitioning.
● unknown - The metro node encountered a problem
determining the operational status of the cluster. This
may indicate a degraded state, since it usually means
that at least one of the directors is not responding or is
communicating abnormally.
Health State
● critical failure - The cluster is not functioning and
may have failed completely. This may indicate a complete
loss of back-end connectivity.
● degraded - The cluster is not functioning at an optimal
level. This may indicate non-functioning remote virtual
volumes, unhealthy devices or storage volumes, suspended
devices, conflicting director count configuration values,
out-of-date devices, and so forth.
● ok - The cluster is functioning normally.
● unknown - The metro node cannot determine the cluster's
health state, or the state is invalid.
● major failure - The cluster is failing and some
functionality may be degraded or unavailable. This may
indicate complete loss of back-end connectivity.
● minor failure - The cluster is functioning, but some
functionality may be degraded. This may indicate one or
more unreachable storage volumes.
Islands:
Island ID
ID of the island. For current release, always 1.
Clusters
Names of clusters belonging to the island. For current release,
always cluster-1 or cluster-2.
