The node is a Windows 2019 RDS session host using profile disks. I don't want to monitor the user disks (and they raised alarms with no apparent reason), so I deleted them: Manage Nodes -> click the arrow on the left of the node -> select the disks -> delete
Now the node is in warning: "Node status is Warning, C:\Users\xyz Label:User Disk 30231C72 Down."
I manually polled and rediscoverd the node.
This disk is not in "list resources" anymore and its gone from the submenu of the node in Manage Nodes.
How can I get rid of the warning?
