 [[action-destructive-requires-name]]
 // tag::action-destructive-requires-name-tag[]
 `action.destructive_requires_name` {ess-icon}::
+(<<dynamic-cluster-setting,Dynamic>>)
 When set to `true`, you must specify the index name to <<indices-delete-index,delete an index>>. It is not possible to delete all indices with `_all` or use wildcards.

 [[cluster-indices-close-enable]]
 // tag::cluster-indices-close-enable-tag[]
 `cluster.indices.close.enable` {ess-icon}::
+(<<dynamic-cluster-setting,Dynamic>>)
 Enables <<indices-open-close,opening of closed indices>> in {es}. You might enable this setting temporarily to change the analyzer configuration for an existing index. We strongly recommend leaving this set to `false` (the default) otherwise.

 IMPORTANT: Closed indices are a data loss risk because they are not included when you make cluster configuration changes, such as scaling to a different capacity, failover, and many other operations. Additionally, closed indices can lead to inaccurate disk space counts.

 // tag::reindex-remote-whitelist[]
 `reindex.remote.whitelist` {ess-icon}::
+(<<static-cluster-setting,Static>>)
 Specifies the hosts that can be <<reindex-from-remote,reindexed from remotely>>. Expects a YAML array of `host:port` strings. Consists of a comma-delimited list of `host:port` entries. Defaults to `["\*.io:*", "\*.com:*"]`.
