Table 5. cluster summary field descriptions (continued)
Field Description
Operational Status
● degraded - The cluster is not operating as configured
and is not currently transitioning. Examples include:
degraded redundancy level (a director is dead), all exports
switched to write through because of hardware health
problems, suspended virtual volumes, suspended exports,
storage volumes not visible from all directors, meta-volume
not yet processed.
● isolated - The cluster is not communicating with any
other clusters.
● ok - The cluster is functioning normally.
● transitioning - The cluster is reacting to external
events and may not be operating as configured. I/O may
be suspended during the transition period.
● 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out-of-date devices, and so forth.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.
