This prevents indices from remaining unallocated if there are no nodes in the cluster for the preferred tier. For example, when {{ilm}} migrates an index to the cold phase, it sets the index `_tier_preference` to `data_cold,data_warm,data_hot`. To remove the data tier preference setting, set the `_tier_preference` value to `null`. This allows the index to allocate to any data node within the cluster. Setting the `_tier_preference` to `null` does not restore the default value. Note that, in the case of managed indices, a [migrate](elasticsearch://reference/elasticsearch/index-lifecycle-actions/ilm-migrate.md) action might apply a new value in its place.
