Hello
On my company we have 3 data nodes connected on a master node
I need to define a lifecycle policy
But to do so I need to define which node is hot, warm, and cold
my question: can I define a node with several types? hot And warm?
Thank you

It doesn't make sense to have a node that is both hot and warm. What's your reasoning behind wanting to do that?

Hello @Kwiskas
The Index Lifecycle Policy phases do not require hot, warm and cold zones in the cluster ([documentation](https://www.elastic.co/guide/en/elasticsearch/reference/master/ilm-index-lifecycle.html#ilm-index-lifecycle)).
The phases are more linked to the lifecycle of the index.
It is possible to force the allocation / migration of the indices to a specific group of nodes when the index lifecycle reaches a specific phase using the [allocate action](https://www.elastic.co/guide/en/elasticsearch/reference/master/ilm-allocate.html), but it is optional.
The phases have a fixed order (hot ❯ warm ❯ cold ❯ delete) and the actions within each of them have a fixed order too ([see this list](https://www.elastic.co/guide/en/elasticsearch/reference/master/ilm-index-lifecycle.html#ilm-phase-actions)) and they're optional.
Let us know if you have any doubt.

Hello Luca
Thank you for your reply
My question comes from that when I try to define the index lifecycle policy on kibana, it gets me an error:
No node attributes configured in elasticsearch.yml
You can't control shard allocation without node attributes.
This is because i have not defined yet on my nodes which one is the hot and which one is the warm
what I wanted to know is can I define both of my 2 nodes as hot AND warm so I dont have to use only one actively and the other one not.

Hello @Kwiskas
The message:
```auto
No node attributes configured in elasticsearch.yml
You can't control shard allocation without node attributes.
Learn about shard allocation
```
Is just a warning. You can proceed further.

Oh. Thank you; I didn't knew it was a warning. This can be closed.
