Mixed just means the node is partially full. It has nothing to do with the health of a node. Down/Drained/*(where the node name is followed by a *)/unavailable are all bad states. You will see compound states as well such as DOWN+DRAIN or IDLE+DRAIN or ALLOCATED+DRAIN. They indicate exactly what they are. Namely the IDLE+DRAIN means that the node has been DRAINED and is IDLE. ALLOCATED+DRAIN means the node is set to drain but is currently fully allocated. MIXED+DRAIN means the node is draining but is currently partially allocated.
Hope this helps. Generally states that are in a problematic state will have their Reason field filled with something.

Hello, if a node is in a MIXED state, is it possible that there are "good" and "bad" states mixed? I mean, if a node is MIXED when it is partly allocated, this is OK. But is it possible that a node is, for example, partly DOWN or partly DRAINED, or partly in some other state that is not normal? I maintain a script in a monitoring system which checks whether a node is available to SLURM, and it consideres IDLE and ALLOCATED states as "good". I am going to add a MIXED state also, but I don't wont to miss a problem in the way I described.
